Power grid topology analysis method based on knowledge graph

The invention discloses a power grid topology analysis method based on a knowledge graph. The power grid topology analysis method comprises the steps of obtaining each power device in a power grid topology structure and a connection relation between the power devices; constructing a knowledge graph of the power grid according to each power device and the connection relationship between the power devices; determining the number of target entities in the knowledge graph, the number of adjacent entities having a connection relationship with each target entity, and a connection path between each target entity and the adjacent entity; and determining topological structure parameters of the power grid according to the number of the target entities in the mapping knowledge domain, the number of the adjacent entities and the connection path between each target entity and the adjacent entity thereof. According to the method, the power grid topological structure parameters are obtained based on the knowledge graph, the
