Abstract: To further enhance the power supply reliability of the active distribution network, SOP has significant application value in the fault recovery process. It not only can utilize its fast adjustment feature, but also can better accommodate distributed power sources and improve the fault recovery capability. The complete fault self-healing issue involves the collection and output of electrical quantities in the distribution network, protection configuration applicable to the distribution network, fault location and isolation, and the formulation of self-healing schemes. Based on the distribution network with distributed power sources and SOP as the research background, this paper studies the protection configuration of the new type of distribution network containing SOP, and presents a fault isolation and self-healing scheme based on regional information.
