[0002] As the terminal link of power transmission, the distribution network is an important infrastructure to ensure and improve people's livelihood. With the continuous construction of new power systems based on new energy, the power grid structure has become more complex. The operation of the power system involves a large number of equipment and components, which are interconnected through a complex network structure. In order to effectively manage and ensure the stable operation of the power system, it is necessary to have an in-depth understanding and analysis of the topological structure of the power grid, so as to establish a more accurate relationship between distribution network equipment. The traditional topological structure only forms an association between "station-transformer-user", which leads to low efficiency in analyzing factors such as power flow, node voltage, node current, line loss and faults, and cannot quickly locate faulty equipment, resulting in long equipment maintenance time and low resource allocation efficiency.
