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
