Abstract

This study deals with the D-STATCOM used as a shunt connected compensator for the voltage support. The D-STATCOM has a faster response as compared with the conventional compensators such as the synchronous condenser and the SVC. The D-STATCOM can provide voltage support and improve power quality. The D-STATCOM supplies reactive power to the load to improve the voltage stability of the load busses. In this study two control strategies are performed using VSI fed STATCOM for reactive power compensation and power system bus voltage regulation. The fourteen bus system with and without D-STATCOM are modeled and simulated. VSI fed STATCOM is modeled and simulated. The compensators are tested with different loads. The above facts have been verified by using simulation in MATLAB/SIMULINK environment on a five level VSI fed STATCOM under variations of load. The simulated results have been validated through experimental results on a five level VSI fed STATCOM and the experimental results are compared with the simulated results.
