摘要
当前大型抽水蓄能机组的发展动向是：大容量化、高水头化、高转速化与可调速化。而混流可逆式水泵水轮机的比转速的初步选择，可按文中统计公式ｎｓ＝２０９２．６Ｈｒ＾－０．４９７计算，然后进行其它参数匹配。
Today the development trends of large pumped storage units are :large capacity ,high head,high speed and govering.Thus the priminary selection of Francis reversible pump turbine could calcu-late also according to the formula ns=2092·6Hr-0.497,then to match other parameters.
