Abstract

This paper deals with control strategies for DSTATCOM (Distribution Static Compensator) for power quality improvement for a three-phase, three-wire distribution system. A three-leg voltage source inverter (VSI) configuration with a dc bus capacitor is employed as DSTATCOM. The PWM current controllers are designed analyzed and compare for PI controller. The capability of the DSTATCOM is demonstrated through results obtained using PSIM. The performance of the DSTATCOM acting as a shunt compensator is found satisfactory under varied load perturbations.
