可逆式水泵水轮机研究现状综述

摘要

The reversible pump-turbine is usually adopted in pumped storage power stations , which however is of certain design defects.The hump zone and S-shape characteristic of the reversible pump-turbine are introduced.Then, a litera-ture review on the optimization of the reversible pump-turbine is presented , including the optimization design of the tur-bine runner and operation scheme avoiding the S-shape characteristic zone .%抽水蓄能电站大都采用可逆式水泵水轮机，针对可逆式水泵水轮机的设计缺陷，介绍了可逆式水泵水轮机的驼峰区和“S”特性，结合近几年国内外的研究成果，总结了优化转轮设计、机组避开“S”特性区运行等解决水轮机设计缺陷的方法。
