Abstract: This paper deals performance analysis and operating principle of power electronics-based device called Distribution Static Compensator (D-Statcom) used to mitigate voltage sag, swell on a distribution network. The power circuit of the D-Statcom and the distribution network are modeled by specific block from the power system while the control system is modeled by Simulink blocks. A main feeder feeding the load is abruptly disturbed by the inclusion of sudden load thereby creating a voltage sag. This voltage sag is corrected by the static compensator.  The dip in voltage is generally encountered during the variation of load. The model of D-STATCOM connected in shunt configuration to a three-phase source feeding dynamic loads is developed using Simulink of MATLAB software. Simulated results demonstrate that D-STATCOM can be considered as a viable solution for solving such voltage dip problems. In this, the three phase three wire disturbance create of  three phase to two phase, two phase to single phase & single phase to two phase for Linear Load & three phase three wire disturbance is created for Non-Linear Load which is non sinusoidal and to prevent this unbalance system from being drawn from the D-STATCOM. This paper aims at performance analysis of three phase VSC based D-STATCOM for three phase three wire distribution system.
