| 摘 要： | 电力系统稳定器(PSS)是目前抑制电力系统低频振荡最有效的方法之一.在分析了同步发电机励磁控制系统及其模型的基础上,研究了以PSS为辅助控制的同步发电机励磁控制方式,基于Matlab构建了改进的PSS励磁控制系统的仿真模型.在三相短路以及断线故障情况下对单机无穷大系统进行仿真测试,结果表明:加装PSS的励磁控制系统的各方面性能优越于无PSS的励磁控制系统,为励磁系统的设计提供了依据.

| Abstract: | Power system stabilizer（ PSS） is one of the most effective methods to restrain low frequency oscillation in power system.The paper studies into the synchronous generator excitation control with the power system stabilizer as the auxiliary control unit on the base of the analysis of existing synchronous generator excitation control system models.Thereafter a simulation model of an improved excitation control system including PSS is established based on Matlab.A test is carried out on the single machine infinite system for the cases of faults of three phase short circuit or disconnection,and the result show that the performance of the excitation control with PSS is superior to that of the excitation control without PSS.This design provides reference for the improvement of excitation system. |
