N2 - Dynamic voltage restorer (DVR) is utilized to shield delicate loads from harmonic distortion, sag/swell, and unbalance in supply voltage monetarily. In this paper, Fuzzy Logic control based control scheme has been created for the generation of remunerating voltages for controlling DVR. This scheme can controlled both linear and non linear loads efficiently. For creating voltage sag/swell and voltage harmonics, a three-phase programmable voltage source is taken and this voltage is compared with a reference voltage of same magnitude. If there is any disturbance in the system then an error signal is produced which is handled by controller in light of fuzzy logic theory. The controller produces the gate signal for the PWM inverter empowered by a DC source and inverter injects the required voltage to the line and load terminal voltage become tightly regulate. By using MATLAB/Simulink simulation studies is done and the above control strategy is tested. The simulation results for voltage harmonic distortion, voltage sag/swell, and voltage unbalanced reduction utilizing the fuzzy logic controlled algorithm demonstrate the viability of DVR.
