Abstract

This paper discusses the implementation of current source converter based distribution type static synchronous compensator. For eliminating the lower order harmonics, the power semiconductors are switched by pulse width modulation technique. Current source converter, input filter, dc link reactor are combined to design the proposed CSC based STATCOM. Since the STATCOM is a current injection device, the performance of the device is improved by a currentsource converter (CSC) combination. So a controllable current is generated at the output terminals of the device. Filter circuit at the input terminal is designed to eliminate the higher order harmonics. The proposed D- STATCOM is simulated and the results are validated using MATLAB.
