摘　　要：江苏沙河抽水蓄能电站水泵水轮机发电机组由ALSTOM设计制造,经多年运行,两台转轮相继出现空蚀、裂纹、孔洞等缺陷,历经多次维修,均未能彻底解决。哈尔滨电机厂通过自主研发,成功研制出各项性能指标优良的转轮模型,经试验验证,水轮机及水泵能量特性、空化、压力脉动、S特性等主要指标完全满足规范要求,为转轮的优化设计与制造提供了可靠的依据。The pump turbine generator units in Jiangsu Shahe Pumped Storage Power Station are designed and manufactured by ALSTOM.After the operation of many years,defects such as cavitation erosion,cracks and holes are observed in the two runners,which are not yet solved completely after many times of maintenance.Through independent research and exploration,Harbin Electric Machinery Company has successfully developed a novel runner model with excellent performance.Model test shows that the main performance indexes of the turbine and the pump such as energy characteristics,cavitation,pressure fluctuation and S characteristics satisfy the specification requirements.It provides a reliable basis for the optimal design and manufacture of the runner prototype.
