摘　　要：介绍了PSS/E动态仿真、小干扰稳定的仿真分析方法。以四机两区域系统为算例,从联络线传输容量、励磁系统的参数和种类、PSS的参数整定及安装地点选择等因素对系统低频振荡的影响进行了分析,并将动态仿真和特征值分析相结合,相互验证。把各种抑制措施综合在一起对系统进行仿真,结果表明:综合措施的采用,使系统阻尼显著增加,振荡得到快速平息,取得了明显的的抑制效果。In this paper the simulation analysis methord of PSS/E dynamic simulation and small signal stability is introduced.Using the two areas with four generators as example, the factors which influenc low frequency oscillation induding the power transferred by tie line, type and parameters of excitation system, installation location selction and parameters adjustment of PSS is analyzed.The dynamic simulation and the eigenvalue analysis is combined and verified mutually.The simulation which integrat all the suppressing measures is carricedon, The results indicate that： the application of comprehensive measures can increase system＇s damping and calm down the oscillation.The restraining effects is obviously.
