摘要
逆功率保护是抽水蓄能机组特殊的保护之一。结合抽水蓄能电站生产运行的实际情况,对水轮机空载运行不稳定导致逆功率保护动作、监控与保护配合不当导致逆功率保护动作以及断路器跳闸时机选择不正确导致逆功率保护动作的原因进行了详细分析,并提出了具体解决方案。
The revere power protection is one of the special protections for pumped-storage units. Based on the actual operation cases of pumped-storage stations, the reasons of reverse power protection caused by instable no-load operation under generating operation, improper matching between control and protection systems and incorrect trip timing of circuit breaker are analyzed in detail, and corresponding solutions are also proposed.
