Abstract:

In this paper, another control methodology in light of current mode control for Dynamic Voltage Restorer (DVR) is proposed to relieve the power quality issues in the supply voltage. The DVR is controlled in a roundabout way by controlling the supply current. The reference supply streams are evaluated utilizing the detected load terminal voltages and the dc transport voltage of DVR. The control conspire depends on synchronous reference outline hypothesis (SRFT) for the operation of a capacitor upheld DVR. The control methodology is confirmed through broad reproduction ponders utilizing MATLAB with its Simulink and Power System Blockset (PSB) tool stash to exhibit the made strides execution of DVR.
