In this paper, the authors introduce and evaluate an control strategy for downstream fault current interruption in a radial distribution line by using a Dynamic Voltage Restorer (DVR). The proposed controller can be able to compensate the voltage-sag compensation control of the DVR. It independently controls the magnitude and phase angle of the injected voltage for each phase. Digital filters are used to estimate the magnitude and phase of the measured voltages and effectively reduce the impacts of noise, harmonics, and disturbances on the phasor parameters. The results of the simulation studies performed in the Matlab Simulation.
