The Research Of DVR's Protection Strategy

The thesis puts forward the Customer Power technique is valid for transient powerquality problem, assembly with some applied products. DVR based on the line voltagecompensating (LVC) is proposed in the present paper, which is suitable to the mediumvoltage distributing network. The paper systematically studies DVR's putting-into andwithdrawing ways, DVR's over-voltage protection design, DVR's relay-protectionscheme.In the end, the author draws a conclusion that DVR will be widely applied in themedium voltage distributing network in the future.
