INTRODUCTION
Some definitions
Substation automation refers to using data from Intelligent electronic devices (IED), control and automation
capabilities within the substation, and control commands from remote users to control power-system devices.
IEC 61850 is a standard for vendor-agnostic engineering of the configuration of Intelligent Electronic Devices
for electrical substation automation systems to be able to communicate with each other. IEC 61850 is a part of
the International Electrotechnical Commission's (IEC) Technical Committee 57 (TC57)[1] reference architecture
for electric power systems. The abstract data models defined in IEC 61850 can be mapped to a number of
protocols. Current mappings in the standard are to MMS (Manufacturing Message Specification), GOOSE
(Generic Object Oriented Substation Event), SMV (Sampled Measured Values),[clarification needed] and soon to
Web Services. These protocols can run over TCP/IP networks or substation LANs using high speed switched
Ethernet to obtain the necessary response times below four milliseconds for protective relaying.

HISTORIC
Historic - IEC 61850 standard
IEC 61850, the global standard for
communication in substations, is bringing open,
Interoperable, systems, and flexible architectures, to
the substation automation domain.
However, the IEC 61850 is broad and currently not
specific enough to bring interoperable benefits to
TSOs.
Today’s power utilities operate
more globally and require flexible,
future-proof systems to cope with
changing requirements,
philosophies, and technologies.

Historic - April 2012: ENTSO-E statement on IEC 61850 standard
Observations:
• Multi-vendor systems very scarce 10 years after 1st standard publication
• Implementation complexity
Recommendations:
• Improve interoperability, over life cycle of the systems of Assets
• Mask complexity by ergonomic tools
Stakeholders:
• standardization bodies : IEC, … ; Suppliers ; Conformance testing companies: UCA Iug, … ;
Users (associations): ENTSO-E, …

Objectives of the Interoperability Specification Tool
 Tool for DSAS(*) (sub)functions and signals collection @ ENTSO-E level
= profile builder (it is not a specification/configuration tool)
 Future proof (e.g. integration of settings parameter, CIM, interfaces with system
specification and configuration tools, …)
 Basis for gap analysis between IEC 61850 and user requirements
 Facilitator between IEC 61850 complex world (through IEC 61850 UML model) and
utility world, finally enabling multi-vendor interoperability over system life cycle in
an efficient and sustainable way

ENTSO-E profile – TSO methods to provide inputs
• Several methods:
• Conventional schemes decomposition
• Start from existing IEC 61850 modelling
• From scratch
Illustration Elia approach –
Conventional schemes decomposition

Basis: subset of distance
protection subfunctions
2 types of GAP were identified:
• No IEC 61850 LN in the model
• Not enough granularity in the
model

CONCLUSIONS
Conclusions
 Efforts in standardization is an effort on the long term, with potential huge benefits for
ENTSO-E members and the community
 … interoperability over the systems lifecycle is key
for the asset managers
 Efforts to develop an ENTSO-E PROFILE are ambitious but key for the market
 Coordination at ENTSO-E level ensures a strong user position within standardization
bodies
 TSOs need to PARTICIPATE in order to BENEFIT
