Abstract

This paper analyzes the harmonic content in source current and power factor at point of common coupling (PCC) when a single-phase non-linear load fed from wind generator with PI and fuzzy controlled STATCOM at PCC. Non-linear loads induce harmonics in the source components and deteriorate the system stability and reliability. This paper presents STATCOM for harmonic compensation connected at PCC when a two-phase non-linear load is connected at load side. Fuzzy controller yields precise response with quick action time. The paper examines the harmonic distortion in source parameter when STATCOM is connected controlled with PI and fuzzy controllers. The presented system was developed using MATLAB/SIMULINK software and results are presented. Results are presented showing harmonic distortion in source current with STATCOM controlled by PI controller and harmonic distortion in source current with STATCOM controlled by fuzzy controller.
