NEMA technical workshop ABB Connectivity & Smart Grid Ahmed Fahmy,Senior Technical Promoter 18-19 Novmber 2014 Connectivity Industrial process supervision The connection of low voltage devices in communication networks is typically required in: automated industrial processes large industries oil & gas applications smart grid networks Specifically, the capability of combining the control of the industrial process with the supervision of the electrical plant which supplies it is becoming increasingly important. © ABB Group Month DD, Year | Slide 2 Connectivity Integration into systems Low voltage CBs equipped with advanced electronic trip units provide digital communication on several protocols In this way it is possible to connect LVCBs into supervision and control systems LVCBs not only for protection of distribution plants but also for supervision and control © ABB Group Month DD, Year | Slide 3 Connectivity Distribution plant supervision © ABB Group Month DD, Year | Slide 4 Supervision system Distribution plant Communication network Connectivity Distribution plant supervision LVCB as a sensor/actuator in a supervision system Some advantages: Measurement of power/energy for cost optimization and allocation Remote control of circuit breaker Measurement of power quality (power factor, THD, interruptions/sags) Diagnostic data of the circuit-breaker (e.g.: % contact wear) to schedule preventive maintenance Remote information about the circuit-breaker state Remote alarms/warnings to reduce downtime of the plant © ABB Group Month DD, Year | Slide 5 Connectivity Field bus connection Most used fieldbus protocols with LVCBs: © ABB Group Month DD, Year | Slide 6 Connectivity Modbus RTU © ABB Group Month DD, Year | Slide 7 Modbus RTU It is an open, serial protocol derived from the Master/Slave architecture. It is widely used within Building Management Systems (BMS) and Industrial Automation Systems (IAS). Modbus RTU is wide accepted because: It is an ease of use and reliable protocol It is an open and royalty-free protocol Connectivity Profibus DP Centralized controller (PC/PLC) Slaves © ABB Group Month DD, Year | Slide 8 Profibus DP (Decentralized Peripherals) It is a standard for fieldbus communication in automation technology It is a master/slave protocol used to operate sensors and actuators via a centralized controller It is mainly used in factory automation. Connectivity DeviceNet © ABB Group Month DD, Year | Slide 9 The DeviceNet It is a master/slave communication protocol in multidrop network designed to connect simple devices (e.g sensors, actuators) and automation systems in general. It is mainly used in industrial applications for communication between PLC and motor starters, motor controllers, drives. Connectivity Fieldbus Connection Global market share by industrial network Technology development Profibus DeviceNet Modbus TCP Ethernet/IP Modbus Profinet IEC61850 Market development © ABB Group Month DD, Year | Slide 10 Market maturity Market decline Connectivity Fieldbus Connection The use of Ethernet technology is increasingly being used because: Adopted worldwide High data baudrate (up to 100 Mbit/s) Common use of infrastructure and integration with Internet/Intranet Wide availability of devices and standard components (e.g.cables/switches/hubs) Easy of use and integrate industrial devices from different vendors Simple to integrate with networks that already exist in the business office environment Compatibility with many standards Ability to connect and address more devices over longer distances and wider areas.
