Research on Rapid Fault Location Method of Distribution Network with Distributed Power Source

The establishment of the “double-carbon” goal has prompted the spurts of distributed power development. The large-scale grid integration of distributed power sources has transformed the distribution network from a traditional passive network to a more active distribution network, and its complex topology, bi-directional variability of currents, and uncertainty of power output have challenged the traditional fault localization technology of the distribution network. In view of the shortcomings of the traditional fault location method of distribution network, this paper designs a fault diagnosis and fault location model of distribution network with distributed power generation based on the research of accurate fault location method of distribution network based on information inference, and verifies the effectiveness of the fault diagnosis and fault location method proposed in this paper through IEEE34 node case analysis.
