Optimum Time Coordination of Overcurrent Relays using Two Phase Simplex Method

Abstract

Abstract—Overcurrent (OC) relays are the major protection devices in a distribution system. The operating time of the OC relays are to be coordinated properly to avoid the mal-operation of the backup relays. The OC relay time coordination in ring fed distribution networks is a highly constrained optimization problem which can be stated as a linear… (More)
