ENHANCEMENT OF POWER QUALITY IN DISTRIBUTION SYSTEM USING D-STATCOM
ABSTRACT
This paper presents the enhancement of voltage sags, Harmonic distortion and low power factor using Distribution Static Compensator (D-STATCOM) with LCL Passive Filter in Distribution system. The model is based on the Voltage Source Converter (VSC) principle. In this circuit the used control technique is PI control technique with the D-STATCOM injects a current into the system to mitigate the voltage sags.LCL Passive Filter Was then added to D-STATCOM to improve harmonic distortion and improves power factor. In this paper the extension is changing the controller instead of PI controller we can use the Fuzzy controller with the help of fuzzy controller again we can calculate the total harmonic distortion and power factor. Now we can compare the output results of PI and Fuzzy, the fuzzy output give best results then compare PI controller this total blocks were performed using MATLAB SIMULINK.
