摘要
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。
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.
