Abstract

The Dynamic Voltage Restorer (DVR) is the series connected Custom Power Device (CPDs) to compensate voltage based distortions such as voltage sag, swells, unbalance and harmonics, flickers etc. for a linear & non-linear sensitive load. In this paper, a three-phase three wire battery supported DVR is considered to compensate voltage sag, swells, unbalance, harmonics and their combinations in supply voltage for linear loads. A well known Synchronous Reference Frame Theory (SRFT) has been used to generate the required voltage injection by DVR. MATLAB/SIMULINK based simulation results are demonstrated to verify the performance of battery supported DVR.
