Abstract

This paper deals with digital simulation and control of four leg voltage source converter based Dynamic Voltage Restorer(DVR). The control of DVR that injects a voltage in series with a distribution feeder is presented. DVR is a power electronic controller that can protect sensitive loads from disturbances in supply system. It is observed that DVR can regulate the voltage at the load during an imbalance in the three phase system voltage. It eliminates the presence of zero sequence components in unbalanced system to make the system balanced. Circuit model is developed and the same is used for simulation studies.
