两台水轮发电机开关跳闸事故原因分析及防范措施

The cause analysis for the two turbine generator out of order and prevention measure

水轮发电机组经常承担电网调峰发电任务,对电力系统的安全稳定运行起着重要的作用。笔者就某水电厂1号、2号水轮发电机组(20MW*2)开关跳闸事故作了分析,并提出防范措施,避免类似事故的重复发生,以保证水轮发电机组的安全稳定运行。

The turbine generators always takes on regulating the peak consumption of electricity network,and bear the main action for the safe stability performance of the electric power system.This paper taking No.1 and No.2 generator accident of the hydropower as examples,puts forward the prevention methods against the same accident to happen again and ensure the generator to function safely and be stable.
