Abstract

Abstract: The problems occurred in debugging of unit No.5 generator protection of Wanneng Tongling Power Generation Company, such as the stator grounding, the rotor grounding, the various power protections and the reliability of the auxiliary power switchover, were analyzed. The matters needing attention in debug and setting process of REG 670 protection were expounded. The results of this paper can be used as reference for unit No.6 and other large units in generator protection debugging.

Key words: auxiliary power switchover, generator, grounding, power protection, REG 670 protection, debug
