Three Phase Four Wire Dstatcom Strategy for Power Quality Improvement Using T Connected Transformer

Abstract

In this paper, an enhanced three-phase four-wire distribution static compensator (DSTATCOM) based on a T-connected transformer is proposed which enumerates the techniques for power quality improvement. Improved Instantaneous Active and Reactive Current Component theory is employed here. This approach significantly compensates reactive power, phase current harmonics and neutral current. Extensive simulation studies have been carried out in MATLAB/Simulink environment to show the efficiency of the proposed compensator, using power system block set toolboxes.
