【Abstract】 Small signal method is used to derive the frequency response of a thyristor controlled series capacitor(TCSC) A small signal current is imported into TCSC,then the voltages and currents of TCSC and their spectral analysis are presented,at last the frequency responses of TCSC are obtained The study is important for sub synchronous resonance(SSR)as well as other harmonics related and the method could be applied to the analysis of other flexible alternating current transmission system(FACTS)devices Electric magnetic transient program(EMTP)simulation also be used to verified the validity of the method更多还原
