Abstract :
In this paper, a new topology of DSTATCOM (Distribution Static Compensator) is proposed consisting of a two-leg VSC (voltage source converter) and a zig-zag transformer for power quality improvement in three-phase four-wire distribution systems. The DSTATCOM along with a zig-zag transformer is employed for the compensation of reactive power for the voltage regulation or power factor correction along with elimination of harmonic currents, load balancing and neutral current compensation at the point of common coupling (PCC). The performance of the proposed DSTATCOM system is validated through simulations using MATLAB software with its Simulink and Power System Blockset (PSB) toolboxes.
