Research of Low-frequency Oscillation Analysis Basee on Power System Analysis Software PSS/E
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.
