摘要
由于水泵水轮机本身的特性,水轮机全特性图上的“S”形特性对抽水蓄能电站的日常运行有着深刻的影响。针对“S”形特性,从物理上分析了其产生的原因,从理论上分析了其影响,结合实际,剖析了“S”形特性对抽水蓄能电站日常运行的影响,并介绍了常用的解决方法。
Because of the characteristics of a pump turbine, the S-shaped characteristic of water turbine deeply affects the daily operation of a pumped storage power station. This article gives analyses of the causes of the S-shaped performance physically and the influences theoretically. Then the influence on the daily operation of a pumped storage power station is described and some ways to solve this problem are also provided in practical uses.
