清远抽水蓄能电站上水库事故检修闸门充水阀设计探讨

Discussion on the Design of Filling Valve for the Upper Reservoir Emergency Gate of Qingyuan Pumped-storage Power Station

在改进惠州抽水蓄能电站上水库事故检修闸门充水阀基础上,经理论计算与分析,提出了清远抽水蓄能电站上水库事故检修闸门上设置充水阀的数量、规格,并推导了充水阀流量和开度的相互关系,以指导不同水位时对充水阀的操作控制。

Based on the actual improvement of the filling valve for the upper reservoir emergency gate of Huizhou Pumped-storage Power Station, the numbers and technical parameters of the filling valve for the upper reservoir emergency gate of Qingyuan Pumped-storage Power Station are proposed by theoretically analysis and calculation. The relationship between the flow and opening of filling valve is also derived to guide the operation of filling valve under different water level.
