摘　　要：可逆式水泵水轮机组运行工况多且转换频繁,其水力过渡过程更复杂,需单独进行计算分析。针对华东地区某抽水蓄能电站输水系统布置,选取合理的导叶关闭规律,借鉴相似机组的四象限曲线,对大波动过渡过程进行数值模拟和分析。结果表明,在所选取的导叶关闭规律和四象限曲线下,各工况计算控制值均满足设计要求,可为相似工程提供一定参考借鉴。In the operation of reversible pump turbine units,there are many operating conditions and frequent transitions,and the hydraulic transition process is more complex,requiring separate calculation and analysis.This paper focuses on the layout of the water delivery system of a pumped storage power station in East China,selects a reasonable guide vane closing law,draws on the four quadrant curve of similar units,and conducts numerical simulation and analysis of the large fluctuation transition process.The results show that under the selected guide vane closing law and four quadrant curve,the calculated control values for each operating condition meet the design requirements,which can provide certain reference for other similar projects.
