Analysis and Treatment of an Excitation System Fault in Feilaixia Hydropower Station

介绍了广东飞来峡水电厂励磁系统1、2号整流桥V1晶闸管熔断器产生故障的原因,对故障原因进行了分析,提出了处理措施,进行了励磁空载试验和发电机并网运行试验,试验结果合格,机组运行正常。

In the excitation system of Feilaixia Hydropower Station, a fuse fault is encountered in the V1 thyristor of the No. 1 and No. 2 rectifier bridges. Possible reasons of this fault are analyzed and treatment measures are proposed correspondingly. No-load test of the excitation system and grid-connected trial operation of the generator unit show that the treatment is effective and the unit operates well.
