Performance of Capacitor Supported SRF based DSTATCOM in Three-Phase Four-Wire Distribution System under Linear and Non-Linear Load Condition
Journal Title: International Journal of Engineering Sciences & Research Technology - Year 2014, Vol 3, Issue 12
Abstract
In this paper, the four-leg voltage source converter (VSC) with capacitor in its parallel, was functioned as a distribution static compensator (DSTATCOM). In three-phase four-wire distribution system, DSTATCOM was proposed for obtaining load balancing, harmonic current reduction and voltage regulation. The proposed technology was based on synchronous reference frame (SRF Theory). This theory was used for generating a reference current or gate pulse for VSC of DSTATCOM. Performance analysis of DSTATCOM under linear non linear loads was carried out and the Simulink results were shown. The analysis was carried out in MATLAB environment using Simulink and SimPowerSystem toolbox. The proposed SRF based DSTATCOM model was seen to be very effective to enhance the power quality of a three phase four wire distribution system
