Reduced-Rating DVR Control with BESS for Voltage Sag, Swell and Harmonic Compensation

P. Chaitanya ^[2] | A. Anbarasan

Abstract: In this paper, the compensation of the voltage sag, swell, and harmonics in three phase system is analyzed using a reduced-rating DVR. For reducing the rating of DVR, different voltage injection scheme are analyzed to minimize the rating of VSC used in DVR. The voltage rating of VSC can be reduced then the DVR rating can also be reduced. By using unit vectors we can determine the load voltage references. The voltages from rotating axis to stationary axis can be converted by using synchronous reference frame (SRF) theory. The remuneration of power quality problem such as voltage lists, swell, and harmonics is shown by utilizing a diminished rating DVR.
