Abstract

This paper presents a Synchronous Reference Frame Theory(SRF theory) based control strategy for Dynamic Voltage Restorer(DVR) using MATLAB/SIMULINK. The DVR is a normal three phase inverter which converts DC to AC and vice-versa using the dc link capacitor. Whenever utility is distorted by voltage related faults, DVR is active and it protects the load from utility distortions. The control strategy for the DVR plays an important role to make the DVR in active condition whenever distortion occurs. SRF theory is a simple and suitable control strategy for DVR. It acts as the heart of the DVR. This paper also deals with how the DVR is performing under three phase voltage distortion conditions using MATLAB/SIMULINK.
