限幅和转速死区是调速器的两种主要非线性特性,本文采用无量纲模型,通过计算机仿真,定量分析了小波动情况下上述特性对水轮机调节系统动态过程的影响,并讨论了自振荡问题。绘制的有关曲线可供估算非线性影响之用。
The limit and speed of the dead zone are two main nonlinear characteristics of the governor. In this paper, the dimensionless model is used to quantitatively analyze the influence of the above characteristics on the dynamic process of turbine governing system under the condition of small fluctuations by computer simulation. Oscillation problems. The relevant curves are plotted for estimation of nonlinear effects.
