A D-STATCOM for Power Quality Improvement Under Different Fault Conditions

Abstract

D-STATCOM has been used to improve the power quality problems, such as voltage sags, voltage swells for different fault conditions. In order to improve the power factor and reduce the harmonic distortions, LCL passive filter is used along with D-STATCOM. The aim of this paper is to compensate the voltage sag and harmonic distortions by designing the D-STATCOM with LCL passive filter across the distribution system. The simulations were performed by using MATLAB/SIMULINK.
