摘　　要：对于不同的工况,抽水蓄能机组需闭锁对应的特定保护,其保护闭锁逻辑非常复杂。正确的闭锁逻辑才能保证保护不出现误动和拒动。文章综合分析了抽水蓄能机组各种工况的特点,研究了处于各种工况下的保护闭锁逻辑策略。For different working conditions, pumped storage units need to block the corresponding specific protection.Its protection blocking logic is very complex. The correct blocking logic can ensure no protection misoperation and rejection.In this paper, the characteristics of various working conditions of pumped-storage units are comprehensively analyzed.The protection blocking logic strategies under various working conditions are studied.
