Capacitor bank control using traditional microprocessor based relays

Abstract

Many of today's microprocessor based relays incorporate varying degrees of programming flexibility. Some of today's more flexible relays combine traditional protection functions and control logic functions inside a single device. Relays that offer this functionality can be used to develop entire control schemes. In this paper, this concept is used to develop a basic control scheme for a five-stage shunt capacitor bank within a single microprocessor based relay.
