Opis

Power quality improvement is an important issue in respect of increasing application for non-linear loads. A group of devices, called Custom Power Devices (CPDs) are in use for power quality improvement. One of the CPD distributed static compensator (DSTATCOM) is proposed for compensating the power quality problems. The DSTATCOM is design for improvement, performance of distribution system under linear and non-linear loads. Especially in non-linear load DSTATCOM inject harmonics current components into the system to improve power quality of source current and source voltage. Further in the proposed systems the rating and size of DSTATCOM is reduced with the help of Star/Delta and Zig/Zag transformer. The proposed systems are employed for the reduce rating of DC current, compensation of harmonic current, reactive power, neutral current, load balancing and the voltage regulation. In this research work comparison of proposed topology of DSTATCOM consisting of a three leg VSC with the Star/Delta and Zig/Zag transformer is employed for power quality improvement. The performance of proposed DSTATCOM system is demonstrated under balanced, non-linear loads in MATLAB/Simulink environment.
