摘　　要：为了减少抽水蓄能电站水泵水轮机设计选型时的困惑,解决参数相近的不同项目最大扬程与最小水头比值选择时较大的差别,增加机组安全稳定运行的基础条件,通过对抽蓄电站定转速混流式水泵水轮机最大扬程与最小水头比值分析研究,总结设计单位和生产厂商的经验数据,结合抽水蓄能行业发展趋势,提出了常用的比值范围供行业使用。通过最大扬程与最小水头比值限值的提出,减少不同专业在蓄能项目前期建设条件选择上的分岐,为抽水蓄能机组的长期安全稳定运行创造条件。In order to reduce the confusion in the design and selection of pump-turbine of pumped-storage power station,eliminate the difference in the selection of the ratio of maximum pump head and minimum head for different projects with similar parameters,and improve the basic conditions for the safe and stable operation of units,the ratio of maximum pump head and minimum head of fixed-speed Francis pump-turbine of pumped-storage power station is analyzed.By summarizing the general experience data of design constructors and manufacturers and combining with the development trend of pumped-storage industry,the common ratio range is put forward for industry.By proposing the limit value of the ratio of the maximum pump head to the minimum head,the disputes between different specialties on the parameter selection of unit in pre-construction conditions of pumped-storage projects can be reduced,and the conditions can be created for the long-term safe and stable operation of pumped-storage units.
