JEE_V5_N4_RP3 New Control Technique Applied in Dynamic Voltage Restorer for balanced and unbalanced Voltage Sag /swell S. Deepa S. Rajapandian Journal on Electrical Engineering 2230 – 7176 5 4 18 22 DVR, Voltage Sag/Swell, Dqo Algorithm Dynamic Voltage Restorer (DVR) is a custom power device used in power distribution networks to protect consumers from sudden sags and swells in grid voltage. This paper discussed abc to dq0 base new control algorithm to generate the pulse. The proposed control scheme is simple to design and has excellent voltage compensation capabilities. Effectiveness of proposed technique is investigated through computer simulation by using MATLAB/SIMULNK software. The simulation results have shown validation of the control system.
