In this paper, a reduced rating T-connected transformer based D-STATCOM has been proposed for power quality improvement in three-phase, four-wire (3P4W) distribution systems. The complete arrangement considered in this work comprises of a three-phase, three-wire (3P3W) D-STATCOM, a T-connected transformer and a single-phase active power filter (APF). This hybrid approach significantly improves the performance of the D-STATCOM under distorted/unbalance source voltage conditions. To show the efficacy of the proposed compensator, extensive simulation studies have been carried out in MATLAB/Simulink (TM) environment using power system blockset toolboxes.
