【Abstract】 This paper introduces the basic function of power system stabilizer(PSS)and static var compensator(SVC).With using Simulation toolbox of MATLAB,simulates a two-machine power system.This software can demonstrate the systematic work process and the related waveform intuitively and accurately.According to simulation result,it analyzes the impact of PSS and SVC on the voltage stability when a single-phase fault or three-phase fault happens.更多还原
