| 摘 要： | 本文依据常用的水轮机调节系统数学模型,对400多组不同参数值下的调节过程进行计算机仿真。将仿真所得的系统性能指标和调节参数分成三组进行回归分析,得出在水流加速时间常数T_w三个不同范围内调节系统的调节时间T_p/T_w,及最大振幅σ和调节系统各系数之间关系的回归拟合式。所得公式具有较高准确度,且简单实用,可供现场水轮机调速器参数整定时使用。

| Abstract: | According to the common mathematical model of the water turbine regulating system, the transients of the regulating system were simulated by computer for more than 4000 groups of different parameters. After dividing the system quality indices and regulating parameters of the simulating results into three groups and making regression analysis, when the water accelerative time constant Tw is in different valuc, the regression equations indicating the relationship between the parameters of regulating system and regulating time Tp/Tw or maximum amplitude a are obtained. These equation are considerably accurate, practical and simple, and they can be used for field settingthe parameters of speed governor |
