Laboratory Simulation of Generator Protection

Abstract—Generator is the most important and costly equipment in the power system. For the reliability of power system, protection of the generator is very important. There are different types of generator protection which are existing in actual field like reverse power protection, stator and rotor earth fault protection, negative phase sequence protection, over current protection, over voltage protection etc. To give a feel and exposure of these protections, hardware simulation is implemented. Protections against six faults and abnormalities have been simulated. This simulation panel has been practically built at the Power System Laboratory of BVM Engineering College, Vallabh Vidyanagar, Gujarat. In this project, we are using contactor instead of circuit breaker. For the protection, we have used electromagnetic and static relays. It is an academic effort to demonstrate the concepts and complicacies of generator protection in the laboratory environment. I .I NTRODUCTION Generator in a ,power ,station requires ,different type of
