Abstract

- power system network consists of number of circuit breakers and relays which are required to
protect costly equipment. The relays in the power system have to be coordinated so as to avoid mal-operation
and hence to avoid unnecessary outage of healthy part of the system. In this paper, the over-current relay
coordination of 230 kV radial industrial power plant is presented using Electrical Transient Analysis Program
(ETAP). It also presents load flow and short circuit analysis of radial industrial power plant using ETAP. This
paper shows the star view of relays which is unique feature of ETAP for coordinating them correctly. Based up
on recorded data of 230kV industrial power plant obtained from IEEE recommended practice for calculating
short circuit currents in industrial and commercial power system. Results obtained are verified by manual
calculation.
