A novel method of Power Quality Improvement and Reactive Power Compensation in a Grid Connected System for Non-Linear Loads Using DSTATCOM for Induction Motor Drive Applications

Abstract

In this paper an attempts has been to analyses the role of DSTATCOM (Distribution static compensator) and located at load side in the distribution system, which can to eliminating or overcome the problems of source side like voltage sag and interruption etc... In order to maintain the power system quality the DSTATCOM will absorb and provide reactive power to mitigate voltage sag, swell, interruption and improve power factor in various conditions. The use of STATCOM for solving power quality problems due to voltage sags, flickers, swell etc., has been suggested. The purpose of STATCOM is to provide efficient voltage regulation during short duration of induction motor starting and thus prevent large voltage dips. The D-STATCOM fed with induction motor performance can be analyzed by using MATLAB /SIMULINK software.
