Abstract

In this paper, a current-regulated distribution-level static synchronous compensator (DSTATCOM) is proposed for real-time unbalanced load compensation in three-phase electric power distribution systems. The main circuit of the DSTATCOM uses multilevel cascade full H-bridge converter with delta-connected configuration, which is suitable for high-voltage, high-power applications. The compensation algorithm of the DSTATCOM is derived in the phasor domain. Preliminary verification of the DSTATCOM is executed with MatLab/SimuLink program. Finally, a hardware prototype is built for testing. Experimental results confirm the effectiveness of the proposed DSTATCOM for real-time unbalanced load compensation.
