Abstract

Supervisory Control and Data Acquisition (SCADA) systems are widely used to automate monitoring and control of substations. Technologies such as high-speed wide area networks, Transmission Control Protocol (TCP)/ Internet Protocol (IP), switched Ethernet and high-performance low-cost computers prove to be potentially promising for increasing reliability and fostering high speed communications within the sub-station. In order to boost interoperability between Intelligent Electronic Devices (IEDs), International Electro-technical Commission’s (IEC) 61850 communication protocol has been established. With this protocol, the devices communicate with each other, thereby simplifying communication issues which were prominent in legacy substation automation protocols. A digital power grid can thus be created by implementing protection schemes modeled with communication configurations with standardized information exchange. As a result, the demand for a Substation Automation System (SAS) which provides high performance, flexibility and is simple to integrate has been fulfilled by means of IEC 61850 communication protocol.
