چکیده
This project presents reactive power compensation in a distribution power system. DSTATCOM (distribution static compensator) is a reactive power compensator for power quality improvement in a three phase four wire distribution system. A voltage source converter (VSC) based DSTATCOM with a zig-zag transformer is used for the compensation of reactive power for voltage regulation along with load balancing, elimination of harmonic currents, and also the neutral current compensation at the point of common coupling. The neuro-fuzzy based system is used to control scheme of the VSC. The zig-zag transformer is used for providing a path to the zero sequence current in a three-phase four-wire distribution system. The performance of the proposed DSTATCOM system is verified through simulations using MATLAB software with its Simulink. KeywordsDistribution static compensator (DSTATCOM), voltage-source converter (VSC), zigzag transformer and neutral current compensation.
