摘　　要：构皮滩水电站位于乌江干流中游的贵州省余庆县境内 ,是乌江干流开发中的控制性工程。其地理位置适中 ,调节性能好 ,是西南地区具有多年调节性能的水电工程。构皮滩水电站装机容量 3 0 0 0MW ,装设 5台单机容量 60 0MW的水轮发电机组。对构皮滩水电站水轮机的额定水头、比转速及比速系数、单位流量、单位转速、空化系数、效率、稳定性等逐一进行论述 ,介绍了基本参数和参数水平。Goupitan hydropower station, a control project for the development of the Wujiang river, is located on the middle stream of the Wujiang trunk river in Yuqing county of Guizhou province, being a carryover storage one in south west China with superior geographic location and regulation behavior. The Goupitan hydropower station will be equipped with 5 units of 600 MW, totally 3 000 MW. This paper presents the major parameters of hydraulic turbines one by one, such as rated head, specific rotating speed and specific speed coefficients, unit flow, unit speed, cavitation coefficient, efficiency, stability etc.
