With the development of the urban power grid, its structure is becoming more and more complex, and the requirements of urban residents for power consumption are gradually improved. When permanent fault occurs in the power grid, it is necessary to restore passive area power quickly. Therefore, it is very important to realize the grid topology analysis and generate the power transfer scheme as soon as possible. In this paper, a method for automatically generating a power transfer scheme based on graph database algorithms and pattern matching is proposed. The grid structure is stored in the graph database in the form of graph, and the main wiring characteristics that may be used in the process of generating the power transfer scheme are extracted from the graph database by double breadth first search algorithm. When an actual fault occurs, the active analysis is carried out according to the alarm information and the grid diagram. Query the equipment that can be the source node of the voltage-loss equipment and the corresponding restore power supply path based on the generated main wiring mode, and generate corresponding switch operations with the actual status of the equipment on the path. An evaluation system for the power transfer scheme based on the quickness of operation and the safety of the system is established to determine the best transfer power supply scheme.
