The Dynamic Voltage Restorer (DVR) has become popular as a cost effective solution for the protection of sensitive loads from voltage sag. By providing proper control scheme the DVR can also be utilized for eliminating other power quality problem such as voltage unbalance and voltage as well as current harmonics This paper presents control system based on repetitive controller to compensate voltage sag, voltage unbalance and voltage harmonics and current harmonics The well –developed graphical facilities available in PSCAD/EMTDC are used to carry out all modeling aspects of repetitive controller.
