摘　　要：竖井式进出水口在抽水蓄能电站上库的应用和研究情况在国内较少。本文结合某抽水蓄能电站上库模型试验任务,利用模型试验及数值计算方法,对某体型进出水口的发电和抽水各种工况下的进出水口流速分布、水头损失、旋涡等水流特征进行了分析研究。从堰型和防涡梁角度进行了体型优化,提出了阶梯防涡梁的优化体型。该研究内容,对于双向水流的流道研究,具有重要的参考价值。Few studies of vertical pipe inlet-outlet of pumped storage plant have been reported in the literature.In this work,a series of hydraulic model tests and numerical simulation of flow velocity,head losses and vortex formation under various operation conditions were carried out for the design of a pumped-storage plant.The original design scheme was optimized through modification of the weir and the anti-vortex beam.This work provides an important reference for the study of bidirectional flow.
