| Abstract: Over the last decade, the "digitization" of the electron enterprise has grown at exponential rates, utility, industrial, commercial, and even residential consumers are transforming all aspects of their lives into the digital domain. Automation systems in the area of power systems are widely accepted today. This paper describes the design of modern intelligent and redundant high voltage substation. The automation system design makes use of bay controllers, which integrate the control, and protection of individual bays into a single Intelligent Electronic Device (IED). These IEDS provide not only control and protection functions, but also fault recording, event recording, equipment monitoring as well as self diagnostic capabilities. Redundant and smart gate ways, replacing the traditional remote terminal unit (RTU) in connecting the switching station to the system control centre. A new communication model developed and standardized as IEC 61850-communiction networks and systems in this modern substations. With the maturing of the IEC 61850, utilities are beginning to implement substation automation systems (SAS) that are based on this new international standard. New IT technologies are new solutions for the protection of EHV/UHV substations. | ||
