JEE_V8_N1_RP3 Venkateswarlu Koppolu B. Ashwin Kumar E. Venkatesh Journal on Electrical Engineering 2230 – 7176 8 1 31 38 Dynamic Voltage Restorer(DVR), Voltage Source Inverter, Injection Transformer, Super Capacitor, Voltage Source Converter (VSC) To mitigate disturbances at the load end, one of the custom power devices such as Dynamic Voltage Restorer (DVR) with super capacitor is used. The super capacitor as an energy storage is to supply real power to the inverter during the disturbances. The operation of the DVR depends on the control strategy. The control strategy used in this paper is SRF theory and Proportional Integral (PI) controller technique is applied to the DVR. The performances of DVR with and without capacitor are evaluated. The simulations are carried out using MATLAB/SIMULINK software. July - September 2014 Copyright © 2014 i-manager publications.
