The object of this chapter is to describe power system applications of microcomputers, particularly in the area of power substation automation.The major functions required in substation automation are reviewed and two applications described. The first one is a digital system for transmission line protection. This application requires a high processing power not generally available with low-cost microprocessor. The design described in this chapter gives the necessary power by implementing a parallel processing scheme. The second application is a voltage regulation system which controls tap changing power transformers. A microprocessor-based system was designed to virtually accommodate any substation configuration.
