Generator protection system with reverse power relay on 1000 KVA 'Cummins' diesel generator at Cepu Human Resources Development Center

Abstract

Each generator is designed to create a certain amount of electricity. However, there are situations when the generator cannot handle the current load. The solution is to employ two or more generators to produce as much power as the number of generators operating simultaneously or synchronizing (parallel generator). Several parameters must be configured throughout the synchronization process, including the phase sequence, voltage, frequency, and phase angle, which must be the same. An operation failure can occur if one of the prerequisites is not fulfilled, resulting in reverse power. The motoring condition is a condition that occurs when the primary mover of a parallel generator fails. A reverse power protection mechanism is required to prevent this motoring. When one of the generator's prime movers fails or the operation fails, the voltage and load will drop. The other generator then feeds another generator. The reverse power relay instructs the generator's main circuit breaker to open the circuit so that no additional equipment is harmed. This research aims to investigate and comprehend the reverse power relay protection system's use.
