摘　　要：抽水蓄能电站较多采用地下厂房形式开发,消防供水水源一般取自全厂公共供水总管,该总管从下水库取水。部分电站下库水位变化较大,当库区水位处于死水位时无法满足厂房最不利点消防供水要求,常规的高压供水系统无法满足此类电站需求。以某电站为例,介绍了低水头高变幅抽蓄电站的消防供水系统设计方案,分析了各类方案的优缺点,总结了消防供水系统联动控制要点。Pumped storage power stations are often developed in the form of underground powerhouses,and the fire water supply source is generally taken from the public water supply main of the entire plant,which takes water from the lower reservoir.Some power stations have significant changes in the water level of the lower reservoir,and when the water level in the reservoir is at the dead water level,it cannot meet the fire water supply requirements for the most unfavorable point of the plant.Conventional high-pressure water supply systems cannot meet the needs of such power stations.Taking a certain power station as an example,this paper introduces the design scheme of the fire water supply system for a low head and high amplitude pumped storage power station,analyzes the advantages and disadvantages of various schemes,and summarizes the key points of linkage control for the fire water supply system.
