Study on the Feeder Selection Method for 10kV Regional Compensation Type Dynamic Voltage Restorer

Abstract:

This paper proposes the designing of regional compensation type Dynamic Voltage Restorer (DVR), and the topology of main circuit, the detection algorithm for voltage sag, the calculation method of reference voltage and pulse modulation method. Based on the different load types of the target substation and the sensitivity to voltage sags, the selection principle of the location of compensation line for regional compensation DVR is proposed, and the realization of substation feeder selection method is illustrated by taking a substation as an example. The compensation effect of the DVR under different fault types are simulated, and the validity and rationality of the designing are verified.
