The Era of Global Standard for SCADA Substation Automation

The IT revolution has encompassed within its realm the electrical power sector by the application of Intelligence in Metering, Protection, Monitoring and Control.

The amalgamation of communication and IT has made it possible for a Real time IT systems to monitor and control, from a central place, by SCADA for the operation of Power Generation, Transmission and Distribution.

A hierarchical structure exists in the transmission and distribution of power since the power is received at a high voltage level in a substation and delivered to a load center through another substation at reduced voltage level. These substations are being transformed from hardwired configurations to a networked platform by leveraging the technological advancements. The technological transformations have brought within its purview Comprehensive Automation of Substation.

This paper brings out the current trend in communication & systems in Substation Automation IEC61850 Standard along with its benefits for improving Quality and Reliability of the Power System. Also, this paper highlights the case study of a real time process control scheme.
