摘　　要：本文介绍了绩溪抽水蓄能电站调速器分段关闭装置结构、工作原理及导叶关闭时间调整方法。通过对甩负荷试验数据分析,验证了高水头电站采用“先慢后快”关闭规律的可靠性,试验数据完全满足调节保证计算要求。为同类型电站分段关闭装置的设计选型提供了参考。This article introduces the structure,working principle and adjustment method of the guide vane closing time of the governor sectional closing device of Jixi Pumped Storage Power Station. Through the analysis of the load rejection test data,the reliability of the "slow first and then fast" shutdown rule for high-head power stations is verified,and the test data fully meets the requirements of the regulation guarantee calculation. It provides a reference for the design of the same type of power station section closing device.
