Power Quality Enhancement in 3P4W Distribution system with Design of Υ/Δ and Zig/ZagTransformer Based DSTATCOM

Abstract

Abstract: - Power quality is solitary of the foremost issues within the gift epoch. With power quality tribulations utility distribution networks, industrial hundreds, sensitive hundreds etc. square measure suffered. Power quality improvement is a crucial issue in respect of accelerating application for nonlinear hundreds. This paper presents the simulation style of a Υ/Δ and Zig/Zag Transformer based mostly DSTATCOM for power quality improvement & performance of distribution system underneath linear and nonlinear hundreds. Especially for nonlinear load DSTATCOM inject harmonics current elements into the system to enhance power quality of supply current and supply voltage. Additional within the planned systems the rating and size of DSTATCOM is reduced with the assistance of Star/Delta and Zig/Zag electrical device. The planned systems is utilized for the scale back rating of dc current, compensation of harmonic current, reactive power, neutral current, load equalization and therefore the voltage regulation. During this paper comparison of planned topology of DSTATCOM consisting of a 3 leg VSC with the Star/Delta and Zig/Zag electrical device is engaged. The performance of planned DSTATCOM system is established underneath nonlinear hundreds in MATLAB/Simulink
