A REVIEW OF Power Quality Improvement by D-STATCOM in Distribution under Various Fault Conditions

Abstract

In this paper we see that D-STATCOM (distribution static compensator ) is used for improving power quality of distribution network during different type of fault occur in system. In this paper we used PI controller and sinusoidal PWM based control scheme. D-STATCOM connected as shunt load with distribution network at load end. This work on VSC(voltage source convertor ) based technique , using this concept maintain constant voltage at load end and by using LCL passive filter eliminate harmonic from system and also improve power factor of system.
