一起600MW机组励磁故障案例分析与处理

Analysis and Processing of a 600MW Unit Excitation Fault

励磁系统是同步发电机的重要组成部分,励磁装置的性能直接影响同步发电机运行的可靠性和稳定性。针对一台600 MW机组励磁装置两次故障造成的跳闸事故,分析励磁装置的故障原因,提出相应处理措施,为今后类似故障的准确判断和及时处理提供借鉴。

The excitation system is the important part of synchronous generator,and the performance of excitation device directly affects the reliability and the stability of the synchronous generator operation.In this paper, the tripping accident caused by two faults is analyzed for the excitation device of a 600 MW generator,the cause of the excitation device is analyzed, processing measures are put forward for references.
