摘要
针对水轮机全特性图上的“S”形特性,从理论上分析了其产生的原因及对抽水蓄能电站运行的影响,并结合实际剖析了“S”形特性对抽水蓄能电站日常运行的影响和常用的解决方法。
During of the designing of a pump-turbine,the 'S' shape performance on the turbine 4 quadrant diagram n_(11)-Q_(11)will deeply affect the daily operation of a pumped-storage power station.This article analyzes the courseof the 'S'shape performance physically and its influence theoretically.The influence in the practical operation of a pumped-storage power station is described.Some ways to solve this problem are presented.
