In this paper A fuzzy logic controlled statcom has been studied to improve the power quality by compensating harmonics and reactive power requirement of the nonlinear load and the performance of a fuzzy logic controlled statcom to control of Voltage in DC side has been studied and compared with the conventional PI controller. The advantages of Fuzzy logic controllers (FLCs) over conventional controllers are that they do not need an accurate mathematical model and the output voltage regulation quality with fuzzy controller is satisfactorily good and realize soft-startup than PI controller.
