Abstract :
The Dynamic Voltage Restorer (DVR) topologies, with compensation schemes that are sag type specific, require information that are not readily available from the conventional characterization techniques. New characterization algorithm which can identify the phase(s) affected and readily can give information on sag magnitude and phase angle jump are necessary. In this paper, instantaneous symmetrical component theory based algorithm for detection and characterization of voltage sags is proposed. Detailed simulation study of the proposed algorithm has been carried out in MATLAB and the results are presented.
