Power quality Enhancement & Mitigating Neutral current in 3P4W Distribution System with DSTATCOM Using TIES

Abstract

Three-Phase four-wire distribution systems face severe power quality issues like poor voltage regulation, high reactive power and harmonics current burden, load unbalancing, excessive neutral current, etc.This creates excessive neutral current each of elementary and harmonic frequency and also the neutral conductor gets full. By integration section shifting into an especially low zero section sequence electric resistance electrical device with single or multiple outputs, substantial reduction of triplen, fifth and seventh harmonics may be achieved. During this Paper the various TIES (Transformer connections) mitigate the neutral current and also the VSC compensates Harmonic current, reactive power, and balances the load. TIES configuration for interfacing to a three-phase four-wire power distribution system and also the needed rating of the VSC is reduced. The insulated gate bipolar junction transistor (IGBT) primarily based VSC is supported by an electrical device and is controlled for the desired compensation of the load current. The DSTATCOM is valid victimization MATLAB code with its simulink and power grid block set toolboxes.
