Power Quality Improvement in distribution system using D-STATCOM

Abstract

The power quality is a major issue in the distribution system. There will be problem occurs regarding reactive power transfer in distribution system due to large power angle even with substantial voltage magnitude gradient. Here a DSTATCOM is used as a FACTS device which can compensate reactive power. D-STATCOM is three phase voltage source converter used to compensate voltage and make the system stable by absorbing and generating reactive power. Here simulink model and control system is designed in MATLAB simulink environment. Here modeling of the D-STATCOM is also given.
