摘　　要：闭锁逻辑是抽水蓄能电站机组保护的核心技术问题,结合进口和国产继电保护装置在几个抽水蓄能电站的实际运用情况,对进口和国产抽蓄保护装置进行了对比分析,介绍了抽蓄保护的闭锁原因、闭锁方式、闭锁条件等,并结合实际录波数据对各保护的闭锁逻辑进行了说明。The blocking logic is a key technique for unit protection in pumped storage power station. Through comparing the applications of domestic and imported relay protection devices in pumped storage power stations, the blocking reasons, blocking ways and blocking conditions of different relay protection devices are analyzed, and the blocking logics are also illustrated based on actual operation data.
