摘要
从发电机励磁系统数学模型入手,研究了以PID控制方式的自动励磁调节器(AVR)为主要控制,附加电力系统稳定器(PSS)为辅助控制的励磁控制方式。给出了该励磁控制方式在电力系统中的建模与仿真。根据励磁仿真的结果分析了带PSS的PID励磁控制系统的控制性能,讨论了不同的PSS参与励磁控制对系统控制指标的影响,横向比较不同的PSS参与调节的励磁系统动态响应曲线,为励磁系统的设计和选择提供了依据。
Based on mathematic model of self - shunt excitation system, this paper studied the excitation modes which took automatic voltage regulator （AVR） as main control and power system stabilizer （PSS） as auxiliary . The excitation modes were modeled and simulated in power system.. According to excitation simulation result, the performance of PID excitation control system with PSS was analyzed, the influences of the excitation control with different stabilizers on system control indexes were discussed, and the dynamic response curves with different stabilizers were horizontally compared. The articles gave references for the design and selection of excitation system.
