Distribution Network Topology Identification Method Based on Knowledge Graph

Accurate topology is the basis for refined management of the distribution network. In order to make full use of the data available in the distribution network when the topology identification work is carried out. This paper combines the data which can be obtained from GIS, PMS and marketing to establish a knowledge graph of the distribution network. Then, based on the data, the topological relationship is identified from the user address and equipment power data. In the case study,taking a residential district in Jiangxi Province as an example. it is proved that the method proposed in this paper can better fuse the distribution network data to identify the topology with high accuracy.
