摘　　要：某泵站位于水利枢纽工程库尾,因水库蓄水,水位升高导致扬程减少,已经超出了原水泵运行范围,需要进行技术改造。经过方案比选,采用增设变频调速设备调节水泵运行速度的技改方案。论述了变频调速范围的确定及实际改造过程中的一些问题及解决方法。The required pump lift parameter of a pump station located at the reservoir tail of a hydropower project decreases due to water level rise.The actual lift range exceeds the stable operating range of the existing pump,so a technical modification is required.After comparison of modification schemes,frequency control equipment is designed to regulate the speed of pump.The author discussed the determination of frequency control range,some problems during actual modification and the solutions.

关 键 词：泵站 技术改造 变频调速
