Building China's Robust
Smart Grid Initiatives
Integrated Data Backbone Network Project
(Phase Ⅲ) for SGCC
Background
State Grid Corporation of China (SGCC) is a
stateowned and the largest electric utilities company
in the world. SGCC provides secure, reliable electric
power support for Chinese social and economic
development, which affects national energy safety
and economic lifelines. SGCC currently operates its
business in 26 provinces, autonomous regions, and
municipalities—more than 88% of Chinese territory.
SGCC has become a leading industry player in terms
of gird construction by consistently building highly
reliable, secure and IT-enabled networks.
Key Challenges
With the rapid expansion of the Chinese economy,
SGCC faced new challenges as its network grew
both in aspects of scale and complexity. These
challenges included the following:
• Like other electric power utilities , SGCC
had become more reliant on information
systems for a variety of applications, such as
Office Automation(OA), Enterprise Resource
4
Planning(ERP), Call Center and Video Conference.
These applications must be transmitted more reliably
and effi ciently with differentiated Quality of
Service, so that SGCC could substantially enhance
their management capabilities and improve decisionmaking effi ciency.
• Major events (such as the Beijing Olympic
Games) and emergencies (for example, the
Wenchuan earthquake and 2008 winter storms)
demanded a more robust network that could quickly
heal itself to ensure services being connected, even
when some network nodes or links became faulty.
Solution
The integrated data network mainly bears SCADA,
office automation, communications, and video
services. These services all have high requirements
for network security and QoS. In response, Huawei
offered a solution that used Multi-Protocol Label
Switching Virtual Private Network (MPLS VPN)
technology to isolate service systems and to improve
network security. In addition, Huawei's VPN QoS
technology provided differentiated QoS for different

SGCC's integrated data network mainly bears
SCADA, office automation, communications, and
video services. These services all have high
requirements for network security and QoS. In
response, Huawei offered a solution that used
Multi-Protocol Label Switching Virtual Private
Network (MPLS VPN) technology to isolate service
systems and to improve network security. >>
VPN services, ensuring that video (such as video conference and video surveillance), IP telephony, and
data services could run securely and reliably.
In SGCC's original integrated data backbone network, national, regional, and provincial networks were
single-linked. If one link was faulty, all the other links could not function properly. Given this situation,
Huawei's solution changed the original single-link topology to a mesh/partial-mesh network topology that
prevents Single Point of Failure (SPOF) and implements redundancy protection for any links. Furthermore,
Huawei's solution used a series of fast protection switching technologies, including Bi-directional
Forwarding Detection (BFD), VPN Fast Re-Route (FRR), and IP Fast Re-Route (IP FRR), to ensure service
continuity. When a network fault occurs, services will complete protection switching within 200 ms, before
service systems can sense the fault. These technologies have laid a solid foundation for the secure operation
of SGCC's services.
SGCC selected Huawei's solution for three primary reasons:
• Huawei's rich experiences in IP network construction and maintenance:
Huawei, as a leading Information and Communications Technology (ICT) solutions provider, has
constructed more than 130 national backbone networks and more than 700 Metropolitan Area Networks
(MANs) for worldwide telecom carriers and broadcasting organizations. In China, Huawei has participated
in China Mobile's IP bearer network project, China Unicom's IP bearer network project and SGCC's power
Dispatch Data Network (DDN) backbone project.
• Industry-leading network reliability technologies:
Huawei's VPN FRR and IP FRR technologies each provide end-to-end network protection within 200 ms,
which has been validated on live networks.
• Large scale deployed routers:
Huawei has shipped more than one million routers to customers world-wide. Offering reliability, stability
and high-performance features, these field-proven routers have helped global customers reduce Operation
and Maintenance (O&M) costs.
Customer Benefits
• Capability of carrying more services
The unified IP network carries multiple services which are isolated logically and treated as differentiated
services. This IP network reduces SGCC's network investment and enhances its ITenabled management
capabilities.
• Enhanced self-healing capabilities
Upon SGCC's network optimization, its network fault rate decreases by 20 percent, and the number of key
network disconnections falls by more than 30 percent.

Huawei IPv6 Facilitates
SGCC's Smart Grid
Development
SGCC's Trial Project of Next Generation
Internet Technologies
Background
SGCC was founded on December 29, 2002. The
company's core services focus on grid development
and operation, and provisioning of secure, costeffective, eco-friendly, and sustainable power
supply. SGCC's services cover 26 provinces across
the country (accounting for 88% of China's total
territory), providing services for 1.1 billion people.
SGCC has over 1.86 million employees. As the
world's largest public sector enterprise, the company
ranked 7th in the Fortune 500 in 2012.
Next-generation Internet plays a key role in smart
grid development and operation. SGCC is making
tremendous efforts to develop next-generation
Internet to:
• Improve the capabilities of providing, bearing,
and supporting services.
• Enhance system security.
• Enable unified management and control.
6
Key Challenges
The data communications network, serving as
one of SGCC's key infrastructures, supports
power generation, transmission, transformation,
distribution, and usage. The network is like SGCC's
nervous system. SGCC needed next-generation
Internet technologies to leapfrog to smart-grid
development. However, the development faced the
following challenges:
• Smart grid needed IPv6 to support the
concurrent access of a large number of smart
terminals.
The smart grid has a large number of terminals.
In addition to communications terminals and
computers used in traditional grids, smart grids also
have dedicated instruments, such as smart meters,
interactive terminals, and grid control devices.
Hundreds of millions of smart grid terminals are
added each year. IPv4 technologies are no longer
One Net: Connect Everyone,
Connect as One
able to meet service requirements due to the limited IP address space. Moving
towards IPv6 would be essential for SGCC to support massive increases in
terminal access.
• Network restructuring must not impact service continuity or system
reliability.
The communications network supports all service nodes and plays an important
role in ensuring the secure, reliable, and stable operation of the smart grid.
Therefore, the network restructuring has high requirements on performance,
speed, security, and reliability.
The communications network's topology depends on the smart grid. The
network has diverse communications methods, devices, interfaces, and
forwarding modes. The transformation must not impact network services.
Solution
SGCC highly appraised the advancement and maturity of Huawei's solution,
electing to use Huawei's NE40E high-end routers to upgrade the existing IPv4
MPLS data network. The new network supports IPv6 access and bears IPv6
services. SGCC launched trial projects in its branches in Shanxi, Ningxia,
Qinhai, Liaoning, and Jiangsu provinces. The projects upgraded the substation
LANs, application platforms, platform LANs, and access networks to support
IPv6 services.
• Huawei has rich experience in IPv6 evolution:
• Solutions: Huawei provides the end-to-end IPv6 network evolution solution.
• Technologies: Huawei supports diverse IPv4-to-IPv6 transformation
technologies.
• Devices: International authorities have certified that Huawei's devices,
boards, and ports fully support IPv6 services.
• Services: Huawei provides professional-grade IPv6 services enabling SGCC
to complete smooth IPv4-to-IPv6 evolution.
• Huawei's NE40E series router has the following features:
• Uses reliable technologies at the network, service, and device layers to allow
service switchover within 200 ms. These cutting-edge technologies provide
end-to-end security protection for SGCC's network.
• Employs Huawei-developed network processors. Each slot has a maximum
routing capacity of 2 Tbit/s. These high-end routers have the industry-leading
port density and significantly improve network scalability.
• Provides port-oriented five-level QOS to enable QoS for diverse services and

to ensure the stable operation of key services.
• Follows the industry trend of eco-friendly grid
design and adopts energy-saving components for
the routing platform. The power consumption
of each GE port is less than 1 W, which is 30%
lower than the industry average.
Customer Benefits
SGCC chose Huawei as its partner to implement
next-generation Internet technologies and
upgrade the smart grid's communications
network. This choice brings SGCC the following
benefits:
• Smooth evolution in trial projects: SGCC's
backbone network and pilot branch LANs now
fully support IPv6 services.
• Higher network reliability: SGCC now has
the industry-leading basic network platform,
laying a solid foundation for SGCC's smart grid
development.
• F u t u r e - p r o o f n e t w o r k d e s i g n : T h e

In Electric Power
Construction of a
Reliable Optical Network
for the World's Largest
Hydroelectric Enterprise
China Three Gorges Project Corporation (CTGPC)
Fiber Ring Communication Network Project
Background
China Yangtze Three Gorges Project (TGP), as one
of the biggest hydropower-complex project in the
world, ranks as the key project for improvement and
development of Yangtze River.
The China Three Gorges Project Corporation
(CTGPC) was founded in 1993 with registered
capital of CNY111.598 billion and about 14,000
employees. As part of the initiative to build the
Three Gorges Project and develop the Yangtze River,
CTGPC was authorized to develop the hydroelectric
resources in the main river and tributaries of the
upper reaches of the Yangtze River and to build four
massive hydropower plants.The four hydropower
plants will have a total installation capacityof 385
MW and will produce 175.3 TWh of electricity per
year, making the Three Gorges Project the world's
largest hydroelectric project.
8
Key Challenges
In 2003, CTGPC constructed an optical network
for communications services with synchronous
digital hierarchy (SDH) devices. As communications
services of the Three Gorges project continuously
increased over time, the existing bandwidth and
operating mode were insuffi cient to meet present
and future service requirements. In fact, some
devices were no longer even manufactured and spare
parts were unavailable. The original optical network
was in a precarious state.
• Network reliability
Mission Critical services (power dispatching,
emergency command, office automation (OA),
telephone dispatch, and video surveillance
services, etc.) in the Three Gorges project had high
requirements for communication network reliabitlity.
Any incidents, such as device faults, fi ber cuts, and

Huawei provided an optical
network solution for China Three
Gorges Project Corporation
(CTGPC), which guaranteed

hydroelectric services. Besides,
the easy and unified management
system reduced the operating
costs. >>
network management system breakdowns would put the operation of key
services at great risk. So the solution providers had to take all these threats
into consideration.
• Network integration
The geographic environment in Three Gorges was so complicated to lay the
fiber in some place. Some nodes were not suitable for laying out fibers.
Services were supposed to be connected through the optical network and
microwave. To improve operation and maintenance (O&M) efficiency and to
enable quick troubleshooting, the optical network and microwave had to be
seamlessly integrated.
Solution
After a thorough analysis of customer's service requirements and existing fiber
resources, Huawei offered a transmission network solution with following
outstanding benefits:
• Comprehensive network protection strategies
This project planned to construct two fiber ring networks. To prevent services
from being interrupted by several fiber cuts, Huawei's solution used the
automatically switched optical network (ASON) technology to implement
services as permanent 1+1 protection mechanism at the diamond level.
Huawei's solution used a device-level protection mechanism by way of 1+1
hot backup for core components in OSN devices, such as the cross–connection
board, main control unit, and power supply unit. When one board was faulty,
the backup board would immediately take over services to prevent the device
breakdown.
Huawei's solution deployed one U2000 (a network management system) at
the pivotal center and cascaded dispatch center. To improve network security,
VERITAS (a third-party software) was configured to monitor the network
management system and application services in real-time. In this way, a
geographic hot backup was deployed to improve system reliability.
• Seamless integration of the optical network and microwave
Huawei's microwave equipment was embedded with the switching matrix,
and could be integrated with the optical network
to form a mixed networking of wireless and wired
networks. In addition, U2000 is an integrated
network management system. It is able to manage
the transmission network, access network and
datacom devices simultaneously to export endto-end fault analysis reports. These reports will
help quickly locate the faulty nodes, reduce
management blind spots among conventional
network management systems, and further
improve O&M efficiency.
Customer Benefits
• Highly reliable transmission network,
to guarantee the stable operation of core
hydroelectric services
This project comprehensively and considerably
improves the robustness of the network in terms
of device, service, and network-level reliability. In
particular, this project concentrates on developing
CTGPC's advantages and leveraging its abundant
fiber resources to construct an ASON network to
guarantee stable operation of its key services.
• Unifed network management for wired and
wireless networks to save customer's OPEX,
expanding the transmission network
Huawei owns an integrated management system
for wired and wireless (microwave) networks.
This project takes full advantage of this system
to connect the original isolated network "islands"
and achieves fast end-to-end service deployment
and centralized network protection. This system
also enables the CTGPC to conduct precision
management and O&M of wired and wireless
networks simultaneously.
• Proven new technologies, to set a model
for the power generation industry
As the world's largest hydroelectric project, the
Three Gorges project successfully applies ASON
technology to its communications network to
improve network reliability. The success of this
project stands a model for other power generation
enterprises seeking to construct bearer networks.

Shandong Electric Power
Optical Transport Network (OTN) Solution
Upgrades the Backbone Network for
Shandong Electric Power
Background
Shandong Electric Power Corporation (Shandong
Electric Power) is a wholly-owned subsidiary of
the State Grid Corporation of China (SGCC). The
number of 550 kV/220 substations has been growing
at an average of 20 percent every year. By 2015,
Shandong Electric Power will have constructed a
smart grid connecting 17 cities, in which main grids
use 500 kV and municipal grids use 200 kV.
Key Challenges
Shandong Electric Power faced the following
challenges when trying to construct a reliable,
nextgeneration and high-bandwidth network.
• High network security and stability requirements
associated with smart grids:
Important critical applications such as the relay
protection have extremely strict security standards
10
and require comprehensive protection strategies. The
new IP and Storage Area Network (SAN) services
are emerging on a large scale and establishing new
requirements for communication networks.
• Comprehensive protection strategies to
support complex networks:
The Shangdong provincial backbone network
connects 17 provincial and municipal electric power
centers and 19 substations. The provincial center
is the central node. Three 10 Gbit/s channels are
deployed for each municipal center connected to
the provincial center. All municipal services are
aggregated and backed up in the provincial center.
As a result, the entire mesh network is very complex,
and protection policy plays a key role.
• Evolution from SDH/PDH to IP and SAN
services:
The power company's communications network is
transforming from early 2 Mbit/s services (SDH/

network, and fix network faults for many network
exceptions. The devices support up to 6.4 Tbit/
s non-blocking, centralized cross-connection
capabilities. These devices enable intelligent
cross-grooming between optical wavelengths and
electric granules of GE/ ODU1 (2.5 G)/ODU2
(10 G). At the time of development, Huawei was
the unique provider that could enable flexible
grooming between optical wavelength and electric
granules from ODU0 (2.5 G) to ODUk (k can be 1,
2, or 3).
• Field-proven, mature products:
Huawei holds 80 percent of key patents of OTN.
Huawei has led development and promotion
OTN standards for the last 10 years, and its
OTN products are used by 40 of world's top 50
telecommunication carriers. By Q1 2012, Huawei
had shipped more than 140,000 sets of OTN
devices, and secured more than 80 percent of the
worldwide OTN market share.
Solution
Customer Benefits
Huawei proposed a solution for a robust smart grid that integrated
nextgeneration Optical Transport Network (OTN) and Automatically Switched
Optical Network (ASON) technologies to construct the backbone network.
Huawei's solution had the following three key features:
• Comprehensive protection strategies:
Huawei's solution combined OTN and ASON mechanisms to protect both
optical and electric layers. The ASON-based protection strategy efficiently
protected the communications network from fiber cuts and other man-made
damage, ensuring a more secure and reliable electric power service operation.
The entire network used Huawei OptiX OSN8800/OSN6800 that supports
ASON technology at both electrical and optical layers. Huawei also deployed
Reconfigurable Optical Add/Drop Multiplexers (ROADMs) for complex
nodes and ASON grooming for electrical layers. Huawei OSN8800 devices'
large cross-connection capabilities reduced the space required in equipment
rooms. The OSN8800 supports a maximum of 80 channels, with each channel
supporting data transmission at 10 to 100 Gbit/s.
• Industry-leading grooming capabilities for small-granularity services:
Huawei OTN devices are intelligent Wavelength-Division Multiplexing
(WDM) products that automatically enable switching protection, adjust the
In 2011, Shandong Electric Power began to

Securing Electric Power
Grid Operations
Substation Secondary System Security
Protection Project for GPG
Background
Guangdong Power Grid Corporation (GPG) is
the largest provincial power grid in China, has a
registered capital of CNY48 billion. It directly
manages 36 municipality-level and 79 county-level
power supply utilities.
Key Challenges
The second network security construction of GPG
contains horizontal and vertical links:
Horizontally, the system is divided by production
control area and information management area. The
production control area contains security zone I and
security zone II; information management area contains
servers farm zone (security zone III) and office zone
(security zone IV).
Vertically, the provincial-level dispatch center,
municipality-level dispatch center, and countylevel dispatch center conduct communication
through power dispatching data network and power
enterprise data network.
• Network security
Horizontally, real-time zone I services were core
12
services for GPG with the highest security grade.
However, there was no security network border
between realtime zones I and II. This loophole put
real-time zone I services in danger.
Vertically, data transmission between upper-level
and lower-level networks was frequent; however, the
original network system did not provide effective
measures to safeguard network security. Once an
internal user was attacked by the Internet or used
files that contained viruses or Trojan horses, the
security hazard would rapidly spread across the
network, resulting in large-scale security threats.
• Emergency handling capabilities
As GPG's grid architecture and operating mode
became increasingly complex, faults at any site in
the electric power system would threat GPG grid's
operations. Especially when the fault happened
in high level grid, it would spread throughout the
gird and outage would happen if the fault was not
resolved quickly.
• Network scalability
GPG intended to invest CNY125 billion in the
electric power grid construction in 2010.
Substation quantities (220 kV or more), transformed

In order to solve the security problem of Guangdong Power Grid
Corporation (GPG), Huawei deployed security gateways with

power volume and overall link length were,
respectively, 1.97 times, 2.1 times and 1.96
times higher than those in 2005. GPG's rapid
development set very high requirements for
expansion of the information system and devices.
Solution
Huawei deployed security gateways with diverse
performance capabilities to achieve a risk control
on dispatch data networks and substations.
Horizontally, Huawei deployed USG5000s
in redundant back-up mode on the network
borders between security zones I and II to
isolate transmission of production and nonproduction data. In this way, non-production data
transmission would not affect the transmission of
production and control data.
Vertically, Huawei deployed USG5000s between
upper-level and lower-level networks (in
redundancy backup) to encrypt transmission data
using a 128-bit Virtual Private Network (VPN)
algorithm. Furthermore, Huawei constructed
internal authentication centers to authenticate user
access from lower-level networks to upper-level
networks, preventing malicious intrusions (such as
wiretapping) into the dispatch data network.
Huawei's solution incorporates the following three
key features:
• Isolated data transmission and access
authentication to reduce security risks
Huawei's solution deployed hardware firewalls
between safety zones I and II to strictly control user
access. These firewalls are centrally managed to
improve access control policy efficiency and prevent
unauthorized or illegal access.
Huawei also deployed firewalls within the
information management section, between provincial-level and municipalitylevel dispatch centers, and between municipality-level dispatch centers and
substations. This kept upper-level and lower-level data transmission isolated
to prevent large-scale network security threats.
• Link and two-node clusters redundancy to minimize service interruptions
In Huawei's solution, dual links (in redundancy back-up) are used to connect
the control zone and non-control zone in GPG's dispatch center. Huawei also
deployed one firewall on each link. The two firewalls synchronize traffic and
communication data between each other in order to back up. These measures
effectively decreased the network fault rate and improved network reliability.
The Mean Time Between Failures (MTBF) for these firewalls is up to 500,000
hours, and the protection switching time is less than 0.1s, ensuring service
operation reliability and stability.
• Highly scalable design to help facilitate the strategic goals of GPG
Currently, GPG has constructed the following different voltage substations:
23*500 kV, 200*220 kV and 1,400*110 kV substations. By 2011, GPG would
double the number of the following substations over the next five years:
50*500 kV, 400*220 kV and 2,000 kV substations.
Customer Benefits
• Achieve zero security accident, assisting GPG to fulfill requirements
of No.5 regulation of National Power Supervisory Committee
It’s been two years since the deployment of Huawei equipments. In the past
two years, the regional Power Bureaus and Substations of GPG achieved zero
information security accident, zero information system operation accident and
zero crucial data leakage accident, assisting GPG in satisfying regulations of
the National Power Supervisory Committee.
• Set up solid foundation for the substation digitalization of GPG
planned in the nation’s eleventh five year plan
With its high performance and scalability, Huawei USG series gateway
can achieve smooth expansion of GPG network, both in port number and
performance, greatly reduce the expenses caused by security network
upgrades, avoid the risks of business breakdown caused by bringing new
equipments into network, and significantly reduce the cost inputting in the
substation digitalization of GPG.

Building a Multiservice
Unified Communications
Platform
Distribution Automation, AMI, and
FTTH Project for Beijing Electric Power
Corporation
Background
Established in 1985, Beijing Electric Power
Corporation (BEPC) is a provincial subsidiary of the
State Grid Corporation of China (SGCC). It provides
services to 4.8 million customers in Beijing and
surrounding areas, covering nearly 17,000 square
kilometers.
Key Challenges
Over recent years, BEPC has been striving to
build a Smart Grid, and it urgently needed to
add related systems, particularly distribution
automation and smart metering. The distribution
automation system demands stringent requirements
for network reliability and latency, while the smart
metering system calls for high network reliability,
wide network coverage, and multiservice support.
Services include real-time power consumption
14
data collection, tariff control, telecontrol, abnormal
power consumption analysis, electricity quality
analysis, smart meter archive management, and data
submission to the marketing service management
system, among many others.
However, BEPC's existing systems had faced the
following challenges:
Conventional wireless public networks (GPRS/
CDMA) were not reliable enough. They failed to
meet requirements for high network bandwidth,
wide network coverage, and high network reliability.
As China is enthusiastically encouraging “fournetwork convergence” (smart grid, data, video, and
voice networks), BEPC found it difficult to respond
to this national advocacy because its existing
networks could not support Gigabit Ethernet (GE),
Fast Ethernet (FE), Voice over IP (VoIP), WiFi, and Radio Frequency (RF) video interfaces
simultaneously. As a result, BEPC's networks failed

xPassive Optical Network (xPON) solution
to roll out distribution automation and
Advanced Metering Infrastructure (AMI),
as well as Fiber-To-The-Home (FTTH)
services. The solution deployment had

to meet the convergence towards future networks.
Solution
In response to BEPC's challenges and requirements, Huawei offered a fieldproven xPON solution, which provides the all-service interfaces that BEPC
needs and helps the organization embrace the Internet of Things (IoT) era by
building a connected home network.
Using a reliable, secure local optical network, this xPON solution makes it
possible to transmit collected data securely, efficiently, and all these happen in
real time. This solution also provides various service interfaces (such as RS232,
RS485, GE, and FE) for the user side, accommodating present and future service
demands.
For the Zhonghong and Jianbang residential areas in Beijing, Huawei helped
BEPC deploy several Optical Line Terminals (OLTs) inside the 10 kV power
distribution room, where the OLTs upload data to the control center. Each OLT
provides 16 to 32 Passive Optical Network (PON) ports. Optical fiber composite
low voltage cable (OPLC) is routed out from these PON ports, to optical splitters,
and then to Optical Network Units (ONUs), namely, the Huawei MA5621/
MA5621A, which are deployed in the power distribution cabinet located in the
residential building. The ONUs were then connected to the meters on each floor
of the building through RS485 cables to collect metering information in real
time.
To support FTTH services, BEPC also deployed other types of OLTs inside the
power distribution room. Each OLT provides 32 to 48 PON ports. OPLCs are
routed out from these PON ports to optical splitters, to the Optical Distribution
15
In Electric Power
Frame (ODF), and then to the household power distribution box. The
flat-drop cable is routed out from the household power distribution box
to the in-home ONU, offering a variety of broadband services, including
Internet access, telephony, and television services.
This solution has many compelling features, such as:
• Dedicated electric power terminals feature high security, easy
scalability, and easy maintenance.
• Industrial-grade ONUs use a sealed casting aluminum shell to
protect against water, dust, and corrosion. They can operate normally at
temperatures of as high as 85°C. In addition, these ONUs support 6 kV
surge protection for both user-side ports and power supplies.
• The ONUs provide two uplink ports that use Small Form-factor
Pluggable (SFP) optical modules. The two uplink ports can auto-adapt
to work in an Ethernet Passive Optical Network (EPON), Gigabit
Passive Optical Network (GPON), or GE mode to meet different site
requirements.
• The solution employs a full series of OLTs that adopt a unified
platform and implement redundancy protection for key components
• Huawei's full series of OLTs are well suited for diverse scenarios
requiring small, medium, and large capacities. Unlike similar products
from other vendors, Huawei's OLTs adopt a 1+1 redundancy design for
both main control boards and power supplies, the first-of-its-kind in the
industry.
• The OLTs support GPON, EPON, 10 G GPON, and 10 G EPON
simultaneously and allow a smooth bandwidth evolution to 10 Gbit/s.
• By using unified software and hardware platforms, all OLT service
boards are fully compatible with each other, significantly reducing the
16
One Net: Connect Everyone,
Connect as One
number of required spare parts.
• The solution provides a comprehensive protection mechanism to ensure network
security and service continuity.
• Huawei's xPON solution supports Type B/C/D protection as well as hand-inhand protection. Huawei is also the first vendor to use dual-uplink (hot backup)
technology, in which dual ONU uplinks are connected to the upstream devices.
This dual-uplink design eliminates the need for link switchover and ensures
service continuity.
• The OLTs use Bidirectional Forwarding Detection (BFD) technology in the
upstream direction and work with routers and switches to provide redundancy
protection for uplinks, ensuring network protection.
Customer Benefits
Huawei's xPON solution has brought many benefits to BEPC, including the
following:
• BEPC has optimized its power consumption data collection system into an
IP-based one, signifying a further step towards the IoT era. This new IP-based
system streamlines data collection, facilitates metering, and offers a two-way
communication platform to remotely manage power consumption, enabling
automated smart grid marketing and enhancing marketing and service capabilities.
• With xPON FTTH, BEPC can gradually implement “four-network
convergence,” so users can experience bundled, top-notch triple-play services.
• Huawei's xPON solution uses an efficient Network Management System (NMS)
that does not require a large number of maintenance personnel. As a result, BEPC
can easily manage and maintain the entire network.

SGCC Electrifies Its
Dispatching System with
Huawei's Servers
Background
Founded in December 2002, State Grid Corporation
of China (SGCC) is the largest state-owned electric
utilities company in the world. SGCC serves 1.1
billion people in 26 provinces, autonomous regions,
and municipalities in China, which equals to 88% of
the country's territory.
Key Challenges
The power grid system is a critical part of the
national infrastructure, and its stable operation
is closely linked to people's livelihood and the
economic health of the country. The power grid
dispatching system is the "nerve center" of the
entire power grid system, which ensures the secure,
reliable, and economical operation of the power grid.
SGCC used a system called D5000 as the platform
for the dispatching automation system. D5000 is
a complex system that consists of servers, storage
devices, network devices, operating systems,
databases, middleware, and application software.
D5000 provides a wide assortment of key services,
including Supervisory Control and Data Acquisition
(SCADA), Energy Management System (EMS),
Operations Planning and Scheduling (OPS), Security
20
Checking System (SCS), Operator Management
System (OMS), and Dispatcher Training Simulator
(DTS).
SGCC used an x86 server cluster to replace
traditional midrange computer systems in the D5000
system to provide computing capabilities required
by all SGCC key services. As the foundation of the
D5000 system, the x86 server faced the following
challenges:
Security and compatibility: SGCC concentrated on
the security of servers that are the most fundamental
computing platform. Since 2010, x86 servers
running the secure Linux operating system provided
the infrastructure platform for the power grid
dispatching automation system. The Linux operating
system was customized according to characteristics
of the power grid industry. In this way, the server
that functions as the computing platform must be
highly compatible to run the customized Linux
operating system.
Reliability: The server and storage device reliability
directly affects the proper running of the key service
systems such as the SCADA and EMS systems
and the stable operation of the entire power grid.
All dispatching automation devices must meet the
reliability requirements of the Chinese government,

service. >>
which specifies that the average annual availability rate must be more than
99.99%, and the mean time between failures (MTBF) must be greater than
25,000 hours.
Performance: The power grid dispatching automation system is a realtime processing system. The frontend communication server installed in
the dispatching center needed to process a large amount of telemetry and
telecommand data reported by the SCADA system. Additionally, the server
runs key service systems (for example, EMS) which computed and analyzed
the collected telemetry and telecommand data, to deliver remote control
and commissioning instructions to substations. For example, according to
the industry specifications released by the Chinese government, work status
changes of substations must be reported to the dispatching center within 1s.
In addition, the dispatching center must respond to dispatch tasks of higher
priorities within 2s. For large-sized power grids, midrange computers were
commonly used to meet computing requirements of dispatching tasks.
Solution
After analyzing SGCC's special requirements for IT devices, Huawei enhanced
its cooperation with industry partners such as Beijing Sifang Automation Co.
Ltd and Nanjing Nari-Relays Electric Co., LTD and set up special workgroups
for clarifying customer requirements and designing solutions. After thoroughly
analyzing the customers' requirements on D5000, Huawei proposed a system
consisting of the RH2485 V2 4-socket server, E6000 blade server, and S5600T
storage devices, and conducted technical tests in accordance with SGCC's
requirements.
• RH2485 V2 4-socket server
A variety of online service systems (such as the SCADA and EMS) were
deployed on Huawei RH2485 V2 servers. Multiple RH2485 V2 servers were
deployed in cluster mode to provide computing capabilities for D5000. An
RH2485 V2 is 2U high and supports a maximum of four Intel E5-4600 CPUs
and 1.5 TB memory, which provides high-performance and highly reliable
computing capabilities for upper-layer service applications.
• E6000 blade server
Offline service applications, for example, DTS, were deployed on Huawei
E6000 blade servers. Each E6000 blade server provides space for 10 server
blades in an 8U subrack. One subrack supported a maximum of 40 CPUs,
which provides strong computing capabilities
for DTS. In addition, the Huawei E6000 blade
server also supports both GE and FC switching
modules, which simplifies the system architecture
and provides an integrated computing and network
solution that satisfies DTS requirements.
As for the "x86 server + Linux operating system"
infrastructure platform, Huawei servers can be
adjusted and optimized based on customers'
requirements, which greatly enhances the platform
compatibility and ensures security of upper-layer
service applications.
Customer Benefits
Huawei servers and storage devices have been
widely used for the D5000 dispatching systems
at SGCC and its subordinate provincial power
companies.
• High security
Huawei's servers leverage a variety of innovative
technologies and customer-specific onsite
optimization functions to ensure high security
for the power grid dispatching system. Huawei's
servers and storage devices have passed security
and compatibility tests conducted by third-party
software.
• Lowered TCO
Huawei's RH2485 V2 and E6000 have helped
the customer reduce maintenance costs by 30%
compared to similar products. Meanwhile, the
high-density E6000 blade server decreases about
50% footprint and 10% energy consumption
without compromising computing capabilities.
With continuous performance and reliability
increase of x86 servers, the "x86 server + Linux
operating system" infrastructure has become the
mainstream architecture in the power industry. In
recent years, Huawei has enhanced its cooperation
with industry partners such as Beijing Sifang and
Nanjing Nari-Relays to promote the application of
Huawei's Tecal series servers in China's smart grid
market.
Yu Bin, R&D Manager of Beijing Sifang,
stated, "Because of x86 server's achievements
in performance, reliability, cost-effectiveness,
and technical service, the power grid dispatching
system starts to deploy high-end x86 servers in
batches instead of Unix servers. We have realized
that x86 servers will be more extensively applied
in the power industry, ranging from power grid
dispatching systems to substations."

EPRI Implements Ecofriendly Practices with
Huawei's OceanStor 18500
Background
Founded in 1958, the Electric Power Research
Institute (EPRI) of Guangdong Power Grid
Corporation provides technical research,
development, and application services for
Guangdong Power Grid Corporation and its power
supply bureaus. It is home to 11 dedicated bureaus,
7 advanced testing centers, and 33 labs. To date,
it has received 22 national-level electric power
awards and 31 provincial-level technology awards.
It is a technically-capable research institute with a
comprehensive range of dedicated equipment.
Key Challenges
The EPRI is tasked with developing smart grid
products and implementing eco-friendly practices.
After years of research, the EPRI has achieved
fruitful results in energy conservation. For example,
the EPRI has built a sulfur hexaflouride (SF6)
recycling center that boasts the largest scale,
strongest processing capability, and most complete
testing devices in China. Since its establishment,
the recycling center has processed 16.1 tons of SF6
22
gas (the equivalent of reducing emissions of carbon
dioxide by 382,000 tons) and recycled 14.4 tons of
gas.
The EPRI also has rigid energy conservation
requirements for its data center that bears its
research achievements. According to its IT team,
there was still room for improvement in energy
conservation. IT service systems were deployed
separately, resulting in low resource utilization and
high energy consumption. As a result, the IT team
found an urgent need for an eco-friendly data center.
Solution
The IT team planned to leverage virtualization
technology to improve resource utilization while
reducing energy consumption.
To address customer challenges, Huawei proposed
a high-end storage solution OceanStor 18500 to
centrally store service system data. The solution has
the following highlights:
• High resource utilization
The solution leverages a variety of technologies to
improve resource utilization:

Make Business Agile
Huawei's OceanStor 18500 has helped us
maximize resource utilization, accelerate
response speed to data access requests, and
reduce energy consumption for implementing
eco-friendly practices. >>
• RAID 2.0+: virtualizes and pre-configures hard disks to balance loads, eliminating
idle and hot spare disks.
• SmartMotion: automatically balances data among added hard disks after a capacity
expansion.
• SmartThin: allows the customer to purchase devices based on their requirements,
greatly increasing resource utilization.
• Low service interference
Mutual interference among services is likely to occur after the service data is
centrally stored to a single device. In response, the solution adopts SmartQoS and
SmartPartition technologies to obtain a response delay within 2 ms, protecting key
services from being interfered by other services.
• Low energy consumption
With virtualization and centralized storage, the solution reduces energy consumption
by about 50%.
Six months after the solution was put into use, the EPRI smoothly increased
the controller quantity to 4 and expanded the hard disk capacity to 100 TB to
accommodate new service systems. With the intelligent matrix system architecture,
the solution supports smooth capacity expansion without compromising the response
speed. To accommodate the rapid growth of data volume in the future, the customer
can also smoothly increase the controller quantity to 16 and expand the hard disk
capacity to 7 PB.
Customer Benefits
Huawei's OceanStor 18500:
• Delivers a virtualization architecture to improve resource utilization and eliminates
idle and hot spare disks to avoid unnecessary energy consumption.
• Protects key services from being interfered by other services.
• Supports smooth capacity expansion without compromising the response speed.

Continuity Disaster
Recovery Solution
Safeguards China
Huaneng Group
Background
China Huaneng Group (Huaneng) is the largest
power generation company in China. In 2013,
Huaneng ranked 231st in Fortune 500 Companies.
The company currently has 48 wholly-owned
subsidiaries and branches, with a workforce of
150,000. Its core business divisions cover electric
power, coal, and finance sectors.
Key Challenges
Huaneng considers IT development as a longterm priority. With safety and reliability at the
forefront, Huaneng is dedicated to building a highly
reliable data center to ensure business continuity.
However, the company faced many challenges that
compromised business continuity:
• Huaneng had more than 30 mission-critical
business systems, including enterprise asset
management (EAM), comprehensive database
24
applications, HR management, office automation
(OA), email, and portal systems. These systems
interacted with each other but were disparate in
system characteristics and priorities. One of these
systems had crashed twice, which seriously affected
the company's business. So, what measures could
be adopted to ensure business continuity for all
systems? Huaneng was unable to meet this goal by
simply backing up data. Therefore, after reviewing
all business systems, the company decided to pursue
business-specific end-to-end continuity measures.
• To ensure business continuity, Huaneng required
a disaster recovery (DR) system. The DR system
generally carried no load under normal conditions. If
Huaneng built a homogeneous DR system, it would
incur additional purchases and maintenance costs
as well as significantly waste resources, resulting in
a low price/performance ratio. Therefore, Huaneng
sought a DR system with a high price/performance
ratio that could accommodate their rapidly growing

business demands now and in the future. (Note: In its production systems,
Huaneng had used a large number of UNIX servers.)
Solution
After a meticulous selection process, Huaneng selected Huawei's Business
Continuity Disaster Recovery Solution. Huawei's solution entailed the
following:
• Provided a custom high reliability architecture after a full analysis of
business impact and transaction per second (TPS) on the live network.
After conducting a business impact analysis (BIA) on the live network and
fully considering the characteristics of each business system, Huawei provided
a custom business continuity DR solution with the following features:
• Disparate business systems use varied recovery time objective (RTO) and
recovery point objective (RPO) solutions.
• DR measures are risk-specific, including city incidents, in-building events,
storage system crashes, and host logic errors.
This custom DR solution implements Tier 5 DR defined in SHARE 78
standards, guaranteeing the business system continuity in the face of a variety
of risks.
• Introduced an X86 architecture, replicated database and middleware
data from UNIX servers to X86 servers, and increased the price/
performance ratio by 50%.
Huaneng primarily used UNIX servers in its production systems. Huawei
analyzed the TPS of all business systems running on the live network and
found variation in TPS levels across these systems.
Based on these findings, Huawei proposed to continue using UNIX servers
to build DR for business systems with heavy workloads and to deploy X86
servers to build DR for business systems with light workloads. Huawei also
made it possible to replicate database and middleware data from UNIX servers
to X86 servers. All these factors increased the price/performance ratio by 50%
while not compromising system reliability.
• Reused legacy resources to protect investments.
Huawei's solution was maximally compatible with heterogeneous systems.
It enabled replication of database and middleware data from UNIX servers
to X86 servers, but also fully utilized storage
virtualization products and Huawei's OceanStor
18800 high-end storage system as DR equipment
for the original storage arrays in the product
systems. Therefore, original storage arrays were
reused. This ensured high I/O performance,
enhanced DR capabilities, and maximally
protected investments.
• Fully leveraged network advantages to
support smooth capacity expansion in the
future.
The DR system needed to be able to smoothly
expand to meet future business demands. To meet
this requirement, Huawei provided its CE12800
data center switch — a flagship switch that
supports Transparent Interconnection of Lots of
Links (TRILL), an open large Layer 2 technology
— to flatten the network structure. With its
million-level input/output operations per second
(IOPS) and scale-out architecture, this switch
makes it possible to seamlessly scale up the DR
system.
Customer Benefits
• Business-specific DR, with up to Tier 5 DR as
defined in SHARE 78 standards
• Replacement of the UNIX server architecture
with an X86 server architecture to build DR,
increasing the price/performance ratio by 50%
• Reuse of legacy equipment, protecting
investments worth more than CNYxx million
• Purchase and operating costs reduced by more
than CNYxx million, while not compromising
system reliability

State Grid of China
Powers Up with Huawei
Storage Solution
Background
State Grid Corporation of China (SGCC) was
ranked the 7th largest company in the world in 2011,
according to the Fortune Global 500 ranking, and is
the world's largest electrical utilities company. The
company's core businesses include the construction
and operation of a power network covering 26
provinces, autonomous regions and municipalities.
Its service area represents 88 percent of China's
territory and serves a population of more than 1.1
billion people.
Key Challenges
State Grid uses an Energy Management System
(EMS) to guarantee the security, stability and proper
operation of the electric power system and provide a
sufficient, reliable power supply. To more effectively
accomplish this task, the EMS system was divided
into a series of application systems. Among these
application systems, the Supervisory Control And
Data Acquisition (SCADA) system had the highest
priority and provided data to other application systems,
making SCADA's work effi ciency and data security
essential for the entire EMS. In evaluating revisions to
the existing system, State Grid looked at:
26
• Performance
The SCADA system was mainly used to collect data
returned by Intelligent Electronic Devices (IEDs) in
the electric power system and to transmit the data to
the control zone and management zone systems. The
live network contained a huge number of terminals,
putting enormous strain on SCADA's data storage
capabilities.
• Stability
Since the SCADA system was the primary data
source for all application systems in the EMS, any
faults on SCADA's storage functions would directly
impact operations across the entire system; therefore,
the SCADA system needed to be completely reliable
and stable.
• Security
Within the electric power system, the EMS directly
controls the grid system operation. Any attackinduced faults on the system would cause major
outages.
Solution
The basic SCADA system functions included data
collection, information display, data monitoring,
alarm handling, information storage, report
Make IT Simple,

To support the rapid growth of
power consumption in China, the
State Grid Corporation is building
a large-scale electrical system
with more than 20,000 high voltage
substations. Unfortunately, the
power demand is unbalanced
with the generation requirements,
requiring that power be shifted
between different parts of the
country, based on instantaneous
demand. Controlling this complex
environment requires rapid
access to vast amounts of data,
but State Grid's current storage
systems could match the needs.

generation, event interval recording, and post disturbance reviews. The
thousands of IEDs in the electric power system generate massive amounts
of data related to device status and this information is refreshed every
few seconds, which presents a serious challenge to data storage device
performance.
As demonstrated in earlier tests and verifications, Huawei S5600T devices
achieved up to 1,000,000 IOPS performance ratings and were well suited for
addressing the regional and provincial networks' application requirements. In
addition, the electric power system could enhance the performance of Huawei
S5600T devices through Solid-State Drive (SSD) acceleration to meet future
service requirements, protecting customer's original investments.
• Level-3 acceleration facilitates system performance improvement.
Huawei T series storage devices use next-generation PCIe 2.0 bus and SAS
2.0 high-speed I/O channel technologies. The internal switching bandwidth is
up to 36 Gbit/s. These storage devices provide a solid foundation for overall
storage system performance. When future services
impose additional strain on storage devices,
customers can use the SmartCache feature to
cache data to SSD hard disks to accelerate device
performance or directly use SSD hard disks to
store data.
• Redundant ar chi tec ture minimi zes downtime.
Huawei T series storage devices use dual power
supplies, dual controllers, data safe, hard disk
precopying and hard disk bad sector repair to
ensure the reliability of both the hardware and
software platforms.
• H u a w e i p r o p r i e t a r y s t o r a g e s y s t e m
improves response time.
Huawei T series storage devices use Huawei's
industry-leading, proprietary, high-performance
storage system, which meets customized storage
requirements.
Customer Benefits
• Highly reliable data storage and high-speed
data exchange
Huawei T series storage devices can satisfy even
the most stringent customer requirements due
to their redundant architecture and outstanding
performance. A redundancy back-up design for
components prevents Single Points Of Failure
(SPOFs). A series of software technologies,
such as data safe and file system mirroring,
are available to improve system reliability. In
addition, customers can use host-based agent
software to achieve fast application-level backup,
restoration and disaster recovery. Recent in-field
tests have shown that Huawei's state-of-the-art
storage devices can successfully guarantee the
security and stability of EMS.
• Industry-leading interoperability performance
Huawei T series storage devices work with
software products from mainstream EMS vendors.
To improve the interoperability between them,
Huawei has worked with partners to set up
interoperability labs to ensure that T series storage
devices are interoperable using the latest software
products. These efforts have enabled Huawei to
provide industry-leading IT infrastructure that
ensures secure electric power system operations.

Background
State Grid Corporation of China (SGCC) is the
largest utilities in the world, and also one of the
most essential state-owned enterprises in China.
SGCC provides electricity to more than one billion
users across the country and is crucial to national
energy safety and economic prosperity. SGCC is
committed to provide safe, economical, clean, and
sustainable electric power for social and economic
development. Environmentally conscious and
efficient operations are of primary importance in
completing this mission. Today, China's power grid
carries unprecedented traffic, creating growing
challenges. In response, SGCC is striving to ensure
that the power grid continue running securely and
stably.
SGCC is determined to establish a reliable video
conferencing system to quickly and effi ciently
respond to natural disasters and minimize the
economic and social impact on people's lives.
30
Key Challenges
SGCC's existing SD video conferencing system,
mainly used for office administration, was
constructed in 2000. It has several serious defects,
such as poor image quality and lack of dual-stream
transmission and multi-channel image uploading.
As SGCC raised the stability requirements for power
grid, the original conferencing system faced the
following issues:
• Difficult device management since the
original conferencing system was built with
devices from fi ve different vendors.
The original conferencing system was very
unstable. Management and maintenance personnel
were continually concerned about network
failure, especially when large-scale and important
conferences were held.
• Low resolution and unable to provide
emergency command and dispatch services.

most of China's territory, and the strain on
communications systems was unprecedented. The
original conferencing system could not handle the
workload and was only capable of transmitting
CIF-level images of the affected areas to SGCC
headquarters command center. Image quality
defects seriously affected decision-making when
responding to storm damage.
Solution
Huawei's highly stable, fully-compatible, and
emergency industry-dedicated video conferencing
system addresses customer requirements for
system stability and ease of use.
After in-depth and rigorous consultations with the
customer, the Huawei video conferencing system
was selected to satisfy these requirements. SGCC
is very satisfied with the solution, based on the
following:
• SGCC demanded that the conferencing system
must guarantee around the clock stability. In
response, Huawei incorporated a full redundancy
backup architecture for all Multi-point Control
Units (MCUs), MCU boards, links, and terminals
to ensure that the video conferencing system
continues running uninterruptedly in the event
of Single Points of failure (SPOFs). Tested in
more than one hundred conferences, the full
backup mechanism ensures 24/7 system stability.
Huawei's video conferencing system fulfills the
customer's strict requests for an efficient and
robust system. This system is also compatible with
other products from standard protocol-compliant
vendors (including the five vendors used in the
original solution) to help protect the customer's
original investments.
• Huawei's video conferencing system provides 1080p video
quality, delivers 20 times clearer images than the original
system, and supports multi-channel cascading. In electric power
emergencies, the provincial command center needs to quickly
transfer highquality images from municipalities to SGCC's
headquarters command center. The Huawei VP8660 MCU's
embedded video wall function transfers the images to the
video wall in SGCC's headquarters command center, helping
SGCC executives make decisions quickly and minimize any
repercussions caused by the emergency. For example, when
typhoon Haikui hit the east coast of China in August 2012, the
Huawei video conferencing system played an important role in
responding to the disaster.
Customer Benefits
• Improved system stability and reduced O&M pressure
The customer was extremely satisfied with the 24/7 stability of
the Huawei video conferencing system. The system also shortens
time spent setting up the system from several hours to about a
half hour. The system's stability and ease-of-use vastly improved
Operation and Maintenance (O&M) efficiency over the original
system and resolved many troublesome issues O&M personnel
had previously faced during large-scale video conferences.
• Reduced travel costs and improved work efficiency
According to SGCC's statistics, in one year, SGCC headquarters
held 1,123 telephone and video conferences, with a total of
644,000 participants. If the per-person travel cost is CNY1500,
the Huawei videoconferencing system has helped SGCC save
approximately CNY1 billion.
Once deployed, the Huawei video conferencing system can
simultaneously transmit High-Definition (HD) images from
multiple locations to SGCC's headquarters command center.
These HD images help SGCC executives clearly understand
electric power infrastructure damage in emergency situations
and make quick decisions to minimize the economic and social
impacts on people's lives.

could not help PCCC enhance regulation compliance
or improve communications efficiency due to its
following disadvantages:
• Costly voice communication
PCCC's global branches mostly communicated with
each other using their own voice switching systems
and telecommunications carriers' group services. The
company lacked a private communications network,
resulting in high communications costs.
• Isolated conferencing systems
The legacy video conferencing systems in PCCC's

"95598" Contact Center for Guangxi Power Grid
Background
A wholly-owned subsidiary company of China
Southern Power Grid Co., Ltd., Guangxi Power
Grid Company has 22 branches (14 city-level power
supply bureaus), 43 wholly-owned subsidiaries
(42 county-level power supply bureaus) and one
subsidiary holding company. It also has temporary
jurisdiction over two county-level power supply
bureaus.
Guangxi Power Grid Company constructed its
"95598" contact center system (including interactive
voice response and manual voice services) for
all its city-level power supply bureaus in 2002
and gradually extended the system to its countylevel power supply bureaus afterwards. In 2005,
a customer service center was set up in the
38
headquarters of the city-level power supply bureaus
to monitor all city-level contact centers and handle
incidents reported by customers. In the same year,
an online customer service center was established,
which enabled customers to access various services
without having to go through the power supply
bureaus. To generate a work ticket in response
to a customer request, Huawei’s solution used
C&C08 UAPs to route a 95598 call through a citylevel power supply bureau before automatically
generating a work ticket at a county-level power
supply bureau. This process eliminated the need
for county-level power supply bureaus to interact
directly with customers.

requirements, the need for a new contact center became increasingly urgent.
Key Challenges
In 2009, Guangxi Power Grid Company initiated its plan to construct a brandnew "95598" contact center system. However, in this phase, Guangxi Power Grid
Company encountered the following challenges:
• Out of warranty equipment
The company’s existing contact center devices had been in operation over five
years and were outside the hardware warranty period. In addition, portions of the
software had reached end-of-life, so scalability was a problem.
• Lack of business flexibility
Continuous development of contact center capabilities enables companies to
react to changing business requirements quickly. In the case of Guangxi Power
grid Company, legacy contact center systems were running outdated hardware
and software architectures. As a result, it was very difficult to ensure consistent
services across all power supply bureau areas, and some areas were unable to offer
certain services.
• Management difficulties
Each of the Contact center systems used by the power supply bureaus worked
in isolation from the rest. This made it impossible to establish a pool of agent
resources to be allocated through unified routing, which in turn led to inefficient
resource utilization. For instance, during high call traffic times or emergencies,
some agents would become overloaded, while other agent resources in
other contact centers were idle. In addition, data in each contact center was
independently stored, resulting in poor data integration, problems sharing data and
inefficient monitoring of contact center systems.
• Need to reuse existing equipment
Although the hardware was past warranty and the software deployed was no longer
supported, the systems remained operational. In order to realize the best possible
39
In Electric Power
ROI, the customer needed to upgrade its contact center systems to
accommodate new IP-based functions, while retaining backwards
compatibility with existing equipment.
Solution
Huawei provided the Guangxi Power Grid Company a new "95598"
contact center solution with the following features:
• Centralized deployment and management
All system devices are centrally deployed, with a pool of physically
separated agents sharing a centralized single allocation system. The
system supports agent monitoring, configuration and quality control,
greatly reducing management and maintenance complexity.
• Multi-level backup mechanisms
Two centers are deployed, as well as core devices in a two-node hot
standby cluster, which ensures the proper operation of the contact
center system in the event of a network fault.
Agents can simultaneously access UAP2100s (IP) and C&C08 UAPs
(TDM), which enables and ensures local trunking reliability.
Multi-level backup mechanisms are supported, which enhances the
reliability of the entire contact center system.
• Reuse of existing devices
The existing Huawei C&C08 UAPs are reused to create a TDM backup
link through the E1 trunk, which ensures the proper operation of voice
services if an IP link experiences a fault.
Customer Benefits
• Highly-Reliable contact center system
Leveraging comprehensive security protection mechanisms, tandem
center models, dual backup and dual links (IP and TDM), Huawei
constricted a highly reliable and secure contact center solution for the
customer. This solution has grown into a prototype example for China
Southern Power Grid, and contact center projects throughout China.

Background
China Southern Power Grid Co., Ltd. (China
Southern Power Grid) is a large state-owned
enterprise in charge of the investment, construction
and management of power transmission,
transformation, distribution, etc.
The company wanted to upgrade automatic control
of its power distribution network with wireless
communications technologies. From mid of 2011,
the China Southern Power Grid has started the
construction of small-scale wireless smart grid pilot.
Key Challenges
The construction of a power distribution
communication network faced the following
challenges:
• Unreachable wired network for some areas
44
In the past, China Southern Power Grid constructed
wired networks. However, it was becoming
infeasible to construct wired networks in some
places such as old urban areas. These and other
shortcomings in the existing system led China
Southern Power Grid to investigate broadband
wireless networks.
• High rent cost and poor quality of public
wireless networks
Public carriers' networks, including 2G/3G network,
failed to meet service requirements due to their poor
privacy, high rent cost, and some other insuffi cient
resources. China Southern Power Grid is forced to
find a better wireless coverage mode because of all
of the above limitations.

wireless communications technology is only suitable for simple
business application in a small range, unable to meet the fullservice demands of power distribution automation.
Solution
Huawei submitted an ultra-bandwidth wireless automatic
distribution communication network according to the service
requirements of China Southern Power Grid. This solution is
based on 4G eLTE technology, and it was designed to meet the
needs of distribution automation, metering automation, and
distribution network video surveillance services.
This solution adopted an industry-dedicated wireless spectrum
(1785 - 1805 MHz). Under the Non- LOS conditions, the
solution could provide high bandwidth data access services
in both fixed and mobile scenarios, and also some valueadded services such as emergency communication and video
surveillance.
The solution provides the following features:
• High-bandwidth services with wide coverage and large
capacity:
For base station part, Huawei puts the RRU on towers and uses
multi-antenna technology; as to terminal part, Huawei provides
LTE outdoor data collection terminals which can support IP67
protection level, and they can connect with highgain antenna,
and offer multiple modes specific to a variety of deployment
scenarios. For example, in dense citys where 10 MHz
bandwidth is used, Huawei's solution is below:
• The average throughput of a single carrier can reach 20 Mbps,
and coverage radius is as large as 4 km. The solution can satisfy
the high-bandwidth transmission requirements of distribution
automation and smart metering.
• A single carrier could support up to 1,200 online users, and the
number of online users is up to 10,800 for one cell. The features
well meet the requirement of large capacity for smart gird.
• Minimal access latency for precise control
An automatic power distribution system must precisely
control the power distribution services. Especially for remote
control, the E2E delay should less than 1s. Take the application
layer, network management system and other protocols into
consideration, the maximum acceptable wireless access latency
is 100 ms. To ensure efficient power distribution, Huawei eLTE
uses a minimum access latency solution to ensure it is less than
100 ms. Under "live" conditions, downlink access latency does
not exceed 11 ms (average 8.8 ms), and uplink access latency
does not exceed 59 ms (average 36.9 ms), which fully meets the
requirements of mission-critical applications, such as SCADA.
• Multilevel QoS
Different service applications have different priorities. The LTE
system centralizes radio resource management to ensure endtoend Quality of Service (QoS) based on service levels. Huawei's
LTE QoS mechanism develops priority strategies for multiple
service levels, which ensures that important data, such as remote
control data, is transmitted before other services.
Huawei combined the LTE QoS mechanisms and power service
needs together, and designed the specific priority strategy. The
solution could fully support all the services; meanwhile, it can
ensure the priority transmission of some important data such as
distribution automation remote control data.
Customer Benefits
Huawei's ultra-bandwidth smart grid solution provided three key
benefits to the China Southern Power Grid:
• Verified new mode for power distribution network
This project verified the feasibility of broadband wireless
communication networks for power distribution automation,
while improved the flexibility and reliability in constructing
communications networks.
• Reduced deployment and maintenance costs
Broadband wireless networks efficiently avoided fiber network
construction by establishing wireless coverage in both old
and new urban areas. And all services including distribution
automation, smart metering and video surveillance could be
carried by the wireless networks, so network maintenance costs
were greatly reduced.
• Improved customer satisfaction
Huawei's wireless communication solution improved customer
satisfaction by enhancing power supply reliability and delivering
optimal services.

Background
China Southern Power Grid is a large state-owned
enterprise that handles the investment, construction,
and management of power transmission,
transformation, and distribution across five of
China's southern provinces. Guangzhou Power
Supply Bureau is a large power supply company
affiliated with China Southern Power Grid and
provides power supply services to 10 Guangzhou
administration districts and two counties.
The company announced, in the Technology
Development Planning component of its Twelfth
Five-Year Plan, it would continue researching and
applying new power distribution communications
systems (based on wireless communications
technologies) and focus on upgrading its automatic
power distribution network. To accomplish these
tasks, China Southern Power Grid would construct
an integrated data collection platform and optimize
the power distribution system's data analysis
functions.
46
In mid-2011, China Southern Power Grid began
building small-scale test zones to develop its
wireless smart grid. Guangzhou Power Supply
Bureau was chosen to pioneer the wireless smart
grid and verify whether the smart grid distribution
network could function reliably in highly populated
cities. To this end, Guangzhou Power Supply Bureau
selected Yuexiu District as the pilot area and set
up base stations in the most populated district in
Guangzhou.
Key Challenges
Guangzhou Power Supply Bureau is listed in the
rankings of cities with the largest user density in
China. To improve service efficiency and address
end users' service requirements, Guangzhou Power

terminals (secondary devices with 10 kV or less voltage) from substations to numerous
communities and factories via power supply cables. In Guangzhou, more than 100,000
distribution terminals are scattered throughout the city and are operating in harsh
environments.
Against this backdrop, Guangzhou Power Supply Bureau's smart grid development was
bottlenecked by poor communication efficiency between the power control systems in
the equipment room and the numerous distribution terminals. Over the past few years,
Guangzhou Power Supply Bureau has tried multiple traditional communication modes
to improve efficiency; however, during construction of the traditional communication
modes, Guangzhou Power Supply Bureau was primarily challenged in the following
aspects:
• Some regions had no wired access.
Wired network construction was greatly influenced by the geographical environment.
It was infeasible, if not impossible, to build wired networks in certain areas. For
example, construction projects in populated downtown areas must be reviewed and
approved by government civil labor agencies. Such constructions are complicated with
long implementation periods. In addition, these constructions require excessively high
material and labor costs, as well as complicated follow-up maintenance; therefore,
to better support its service development, Guangzhou Power Supply Bureau chose to
construct wireless networks in these areas.
• Public networks were too costly or failed to meet service requirements.
Public networks failed to meet service requirements due to inadequate confidentiality,
high lease costs, and insufficient service resources. These shortcomings forced
Guangzhou Power Supply Bureau to turn to wireless networks.
• Available bandwidth for short-distance wireless communication was limited
and prone to environment-induced obstacles.
Short-distance wireless communications transmission was limited and substantially
affected by the geographic environment. As such, short-distance wireless
communications could only be used to transmit some simple services on a small scale
47
In Electric Power
and could not meet all power distribution network service requirements.
With the development of 4G wireless communications technologies, China Southern Power Grid
could alleviate many automatic power distribution network construction problems. Wireless
broadband private networks could not only free wired networks from environmental
restrictions but could also overcome 2G/3G public network disadvantages, such as poor
performance and insufficient resources; therefore, the organization preferred wireless
broadband private networks for building the power distribution network.
Solution
To fully address Guangzhou Power Supply Bureau's requirements for simple deployment,
high reliability, and high-speed access, Huawei offered a wireless smart grid solution,
based on 4G wireless Time Division Long Term Evolution (TD-LTE) communications
technologies. The solution set up TD-LTE base stations in the customer's existing
substations and office buildings, operating on an industry-dedicated wireless spectrum of
1.8G.
In addition, Huawei deployed dedicated TD-LTE modules with distribution terminals, such
as Remote Terminal Unit (RTU), Data Transform Unit (DTU), and Feeder Terminal Unit
(FTU). These base stations converge data collected from multiple electric power terminals
and send it to the host station located in the central equipment room via the customer's
existing transmission network. This efficiently connects electric power terminals to power
control systems in the control center, achieving automatic distribution.
Huawei's wireless smart grid solution was developed for the electric power industry to
help customers achieve wide coverage in complex environments and to provide quality
diversified services. This solution includes the following key features:
• High-bandwidth service with wide coverage for a large number of users
• Generally, power stations (such as distribution rooms and ring main units) are scattered
across the city, and base station height is rather low in populated areas. In response,
Huawei used an array of industry-leading technologies, including Multiple-Input Multiple-
48
Boundless,
Professional Wireless Broadband
Output (MIMO), high-gain antennas and High Power Amplifiers (HPAs) to improve
transmission power for enhanced and widened coverage. One base station supports
a 1.5-kilometer coverage radius, ‘five-nines’ reliability, and more than 30 Mbit/s
bandwidth. To this end, Huawei's base stations are providing full access for distribution
terminals around the transformer stations and are satisfying the high-bandwidth
requirements for automatic power distribution, automatic metering, and video
surveillance services.
• Automatic power distribution and automatic metering technologies involve numerous
communication sites. Each site has a small information volume, but, added together, the
total volume can be massive. For this project, Guangzhou Power Supply Bureau needed
to provide concurrent access for more than 400 terminals in one square kilometer. In
response, Huawei optimized access capabilities, enabling one base station to support
more than 3,000 concurrent users. This allows full access for current service power
distribution terminals and supports follow-up capacity expansions to provide access for
a variety of service terminals, including automatic metering and distribution terminals
and charging piles.
• Multiple industry-specific terminal deployment modes
• The bureau’s electric power terminal models varied, requiring different deployment
approaches. Huawei had successfully helped multiple electric power enterprises, such
as Guangdong Zhuhai Power Plant Branch and Dalian Electric Power, build intelligent
wireless networks; therefore, after thorough analysis, Huawei was able to offer diverse
modular deployment modes. For example, underground cabinets and ultra long-distance
deployment were used to improve coverage and enhance communications quality
without compromising operational security and electric power device stability.
• Multi-level QoS assurance and less than 100 ms access latency
• In the automatic power distribution network, different service applications have
different priorities. Based on refined service level-based management, the LTE system
integrates radio resource management to ensure end-to-end Quality of Server (QoS).
Huawei’s customized priority strategies for electric power services, based on the LTE
49
In Electric Power
QoS mechanism, can support multiple services while ensuring that
important data, such as automatic remote service data, is preferentially
transmitted.
This QoS mechanism works with Huawei's industry-leading, real-time
online terminals and flagship solution to minimize latency, ensuring less
than 100 ms end-to-end latency and easily addressing power distribution
network requirements.
Another highlight worth mentioning, Huawei's TD-LTE solution uses an
array of end-to-end data protection methods, including 128-bit Advanced
Encryption Standard (AES) encryption and authentication encryption to
ensure high data security and reliability.
• Fast, high quality delivery
Having built 77 percent of the global commercial networks for
international telecom carriers and setting up multiple wireless smart
grid demonstration sites, Huawei has developed a solid track record
in deploying electric power wireless projects. These projects have
given Huawei an in-depth understanding of customer requirements and
application scenarios. Huawei has considerable experience in wireless
network design, implementation, and service migration, enabling fast
smart grid construction without compromising network security.
Customer Benefits
Huawei helped China Southern Power Grid pioneer the construction of a
wireless megacity smart grid network that offered the following benefits:
• Verification of Central Business District (CBD) wireless smart
grid network feasibility
• As a megacity, Guangzhou has numerous skyscrapers, increasing
electric power terminal deployment difficulties and complicating
wireless network construction. Compared with smaller cities, coverage
and access requirements are more stringent, and Huawei had no
examples to follow. Despite these obstacles, Huawei was able to develop
multiple technological innovations and breakthroughs, meeting China
Southern Power Grid’s requirements for a CBD wireless smart grid.
• Simple deployment and maintenance, improving power
distribution communication efficiency and reducing maintenance
costs
• A single base station in the customer's existing building can provide
greater than 1.5-kilometer coverage radius, enabling regional electric
power terminals to quickly access the smart grid using TD-LTE modules.
Air interfaces connect communication sites, dramatically improving
deployment efficiency of power distribution communication networks
and saving follow-up maintenance costs.
• Multi-service application
• Huawei's solution can satisfy the high-bandwidth requirements of
power distribution network communications and an array of advanced
applications, High-Definition (HD) video surveillance, BYOD, and
multimedia clusters. Huawei's solution helps the customer improve
security monitoring, marketing, and office efficiency and achieve higher
electric service informatization. This project lays a solid foundation for
China Southern Power Grid's future development.
