Fuzzy Controller for Reactive Power Compensation with Statcom to Improve Power Factor

Abstract

This paper deals with modelling of STATCOM along with the design of linear current and voltage controllers. The fuzzy logic control method is used to design linear current and voltage controllers to improve the power factor with the help of reactive power compensation. STATCOM is nothing but the static synchronous compensator which regulates the voltage and corrects the power factor at the point of common coupling by injecting reactive power. The principle of operation is same as that of synchronous condenser. The use of proposed method removes the fluctuations and improves the magnitude of the current and voltage also phase angle which goes to nearly zero value. The performance of the method is obtained through MATLAB SIMULINK tool box.
