GRID SIDE CONTROL BY USING STATCOM AND FUZZY CONTROLLER

Abstract

Now-a-days technology for generating electricity from renewable energy sources such as wind energy, has greatly increased. Because of its non-polluting and economically variable nature, wind energy is considered one of the most important and promising source of renewable energy all over the world. In this paper the STATCOM is used to quickly sense the voltage sag and overcome it. The STATCOM control scheme for the grid connected wind energy. generation system for power quality improvement is simulated using MATLAB/SIMULINK in power system block set.DFIG consist of common induction generator with slip ring partial scale power converter. In this paper presents the total concept is controlling the grid side converter by using STATCOM with fuzzy. thestatcom controller is activated under fault condition and de-activated under normal condition. The method of a three phase grid system with different fault condition is simulated by using MATLAB.
