桃源水电站发电机冷却水泵在运行过程中,曾多次出现在倒厂用电时,冷却水泵软启动装置报故障信号,在厂用电恢复后,冷却水泵无法重启动,从而导致发电机组冷却水中断,引起机组事故停机.针对桃源水电站发电机冷却水泵控制存在的问题,提出了相应的技改方案,避免在倒厂用电过程中引起冷却水泵软启动装置故障,导致机组事故停机的情况.
桃源水電站髮電機冷卻水泵在運行過程中,曾多次齣現在倒廠用電時,冷卻水泵軟啟動裝置報故障信號,在廠用電恢複後,冷卻水泵無法重啟動,從而導緻髮電機組冷卻水中斷,引起機組事故停機.針對桃源水電站髮電機冷卻水泵控製存在的問題,提齣瞭相應的技改方案,避免在倒廠用電過程中引起冷卻水泵軟啟動裝置故障,導緻機組事故停機的情況.

The turbine generator cooling pumps of Taoyuan Hydropower Plant had seen many times the pump soft start device fault signal in case of station service power switching during operation. The cooling pumps even failed to restart after recovery of power supply which led to cooling water supply failure and unit shutdown. In view of this cooling pump control problem,corresponding technical upgrade scheme was put forward.
