摘　　要：对抽水蓄能电站上库充水方式进行了总结,对闸阀、蝶阀、流量调节阀和孔板等管路流量调节元件的水力损失进行了分析比较,认为根据充水泵所允许的最小扬程和最大流量,选取数枚适用孔板,配套安装一台流量调节阀,可保证充水泵在全部几何扬程范围内安全运行。实例计算表明,推荐使用孔板能保证充水泵在合适的区域内运行。The water charging modes for upper reservoir of pumped-storage power station are summarized and the hydraulic losses of flow regulating devices of gate valve, butterfly valve, flow control valve and orifice plate are analyzed and compared. It is concluded that the charging pump can safely operate in whole head range by selecting a certain number of orifice plates and installing an appropriate flow control valve. The case calculation shows that the charging pump can safely operate in suitable range when the orifice plates are used.
