Abstract

A Distribution Static Synchronous Compensator (DSTATCOM) is introducing here to compensate the voltage sag problem by injecting proper reactive current at the point of common coupling. In this paper, the performances and effectiveness of DSTATCOM to nullify the voltage sag are analyzed and a control algorithm based on PI and Hysteresis PWM current controller is developed to verify the results. A 6 pulse Voltage Source Inverter based D-STATCOM is developed using MATLAB simulation program. The model is simulated, first without DSTATCOM and then with it. The results obtained in both the cases are analyzed and which shows the effectiveness of tracking the voltage sag and its correction.
