摘　　要：为确定合适的机组型式、转速等特征参数,确保机组长期安全稳定高效运行,针对湖北钟祥抽水蓄能电站低水头的特点,从国内外工程案例、技术、经济、运行稳定性和运行维护等方面进行综合分析,最终选用立轴、单级、单转速混流可逆式水泵水轮机。通过对装机台数、额定水头和额定转速进行比选,确定了机组的关键参数。研究成果可为同水头段可逆式抽水蓄能机组选型设计以及同类型中小型电站的安全稳定高效运行提供参考。To ensure the long-term safety,stability,and efficiency of the unit,it is crucial to select an appropriate unit type,speed,and other characteristic parameters.Considering the low head characteristics of the Hubei Zhongxiang Pumped Storage Power Station,a comprehensive analysis was conducted,encompassing domestic and international project examples,technological feasibility,economic viability,operational stability,and maintenance requirements.Ultimately,the vertical shaft,single-stage,single-speed mixed-flow reversible pump turbine were chosen.By analyzing key parameters such as the number of installed units,rated water head,and rated speed,we had determined the critical specifications for the unit.The findings can serve as a reference for the selection and design of reversible pumped storage units within the same head range,as well as for ensuring the safe,stable,and efficient operation of similar small and medium-sized power stations.
