Mitigation of voltage sag/swell and harmonics using self-supported DVR

Unbalanced voltage supply is an important issue in distributed network system. In this paper, we proposed a new scheme to control the self-supported dynamic voltage restorers (DVRs). In this scheme, three phase harmonic filter (double tuned) is used to moderate harmonics, generated by voltage source converter (VSC). Total harmonic distortion (THD) is minimized at load bus. By using a reduced-rating DVR, the reimbursement of the voltage dip, voltage swell, and harmonics is demonstrated. Parks Transformation is used to convert the voltages from rotating vectors to the stationary frame. The load voltage is sustained sinusoidal and in phase by inserting properly required compensation voltage through DVR. Extensive experiments are performed on MATLAB platform to analyze the performance of the proposed scheme.
