摘要
为了消除调速侧电力系统稳定控制中调速器间隙非线性造成的自振荡 ,提出了用外加高频周期信号“辗平”调速器间隙实现线性化的方法。应用谐波线性化原理进行了系统分析 ,导出外加高频周期信号的参数设计。最后 ,给出了一个单机电力系统的仿真试验。系统分析和仿真试验结果表明了文中所述方法的有效性。
To damp the self-oscillation caused by governor back-lash in generator governor control, this paper proposes a linearization method of rolling out governor back-lash by adding high-frequency periodic signal. A system analysis is offered by means of harmonic linearization principle. And the formula of parametric designing for additive high-frequency periodic signal are also inferred. Finally a simulation test is given. The results of system analysis and simulation test show the effectiveness of the method.
