摘　　要：笔者结合某水电机组停机失败的案例,探讨了运行水头变化快的水电站如何将运行水头的空载特性应用于调速器控制中,以保证机组安全稳定运行。通过对固定、实时、平均三种运行水头的空载特性进行分析及实际应用,结果表明平均运行水头的空载特性更为适合。该研究可为同类型水电站的调速器控制在应用运动水头的空载特性方面提供借鉴和参考。Based on the shutdown failure case of a hydropower unit,this paper discusses how to apply the no-load characteristics of the operating head to the governor control in the hydropower station with fast changing operating head,so as to ensure the safe and stable operation of the unit.Through the analysis and practical application of the no-load characteristics of fixed,real-time and average operating heads,the results show that the no-load characteristics of the average operating head are more suitable.This study can provide reference for the governor control of the same type of hydropower station in the application of the no-load characteristics of the moving head.
