This document provides relay setting calculations for a generator and associated equipment. It includes details on the generator, system data, protections
It also specifically addresses the coordination of relays with generator full load capability and machine steady state stability limits. Because of recent blackouts, NERC (North American Electric Reliability
First, the Limiter (UEL, OEL, V/Hz Limiter, etc) should be given a chance to address the issue; however, if the Limiter cannot fix it within a certain time, then the relay (40, 24, etc) should trip to protect the
Despite the monitoring, electrical and mechanical faults may occur, and the generators must be provided with protective relays which, in case of a fault, quickly initiate a disconnection of the machine from
