Abstract

This paper deals with a DSTATCOM (distribution static compensator) for load balancing, neutral current elimination, power factor correction and voltage regulation in three-phase, four-wire distribution system feeding commercial and domestic consumers. A four leg voltage source inverter (VSI) configuration with a DC bus capacitor is employed as DSTATCOM. The modified instantaneous reactive power theory (IRPT) is used in the control of DSTATCOM. The capability of the DSTATCOM is demonstrated through results obtained using MATLAB based developed model of the system at different types of loads.
