常规水电站改建抽水蓄能电站的水泵水轮机研究综述

Review of pump-turbine research on conventional hydropower stations converted to pumped-storage power stations

十四五“双碳”目标的提出促进了新能源的发展。考虑到新建抽水蓄能电站带来的技术经济难题,将常规水电站进行抽水蓄能化改造可以促进抽水蓄能电站的蓬勃发展。目前常规水电站改造为抽水蓄能电站相关研究较少,常规水电站改抽水蓄能电站水泵水轮机的设计及优化有待系统研究。本文梳理了常规水电站改造为抽水蓄能电站的优势及水泵水轮机的特点,并对国内外水泵水轮机的设计优化与研究现状进行综述与探讨,结合以上两点分析了常规水电站改抽水蓄能电站水泵水轮机设计所面临的技术难题,以期为常规水电站改抽水蓄能电站水泵水轮机的研究提供一定的借鉴。

The proposal of the “double carbon” target in the 14th Five-year Plan promoted the development of new energy.Considering the technical and economic problems brought by the construction of new pumped storage power stations,the transformation of conventional hydro-power stations into pumped storage power stations can promote the vigorous development of pumped storage power stations.At present,there are few related researches on the transformation of conventional hydro-power station into pumped storage power station,and the design and optimization of pump turbine of conventional hydro-power station into pumped storage power station need to be studied systematically.This paper studies the advantages of transforming conventional hydro-power stations into pumped storage power stations and the characteristics of pump turbines,and summarizes and discusses the design and optimization of pump turbines at home and abroad.Combined with the above two points,it analyzes the technical problems faced by the design of pump turbines in conventional hydro-power stations to pumped storage power stations.It is expected to provide some reference for the research of pump turbine in pumped-storage power station instead of conventional hydro-power station.
