摘　　要：目前水电站的调节品质已成为水电界所关注的一个重要问题。本文从基本方程出发,分析了带尾水调压室水电站负荷扰动下调节系统的调节品质,得出了机组频率尾波波动过程调节时间的计算方法。最后通过计算实例,研究了调速器参数、调压室面积及尾水隧洞水流惯性对调节系统动态品质的影响。The governing quality of hydropower station is a significant problem at present. Based on the fundamental equations,this issue is analyzed for the units with tailrace surge tank,and a calculation method of regulating time of unit frequency fluctuations is derived. Study cases are presented to illustrate the influences of governor parameters,cross-section of surge tank and water inertia in diversion tunnel on the dynamic quality of governing system.
