The embodiment of the invention provides a Neo4j-based power grid equipment information management method, which comprises the following steps of: obtaining input contents of a knowledge graph, and extracting knowledge units from the input contents; Performing semantic description on the extracted knowledge units according to a resource description framework, and determining complex semantic association between efficient computing entities in a low-dimensional space; And performing database modeling based on the Neo4j data model on the obtained complex semantic association content, and determining a topological relation between the power grid equipment according to the established model. Equipment information management is carried out through Neo4j, so that the integrity of data can be ensured; Topological characteristics of a power grid are considered, the problems of low concurrent read-write performance, inflexible increase and decrease of model attributes, low topological analysisperformance and the like when a relational database is used for power grid equipment information management are solved, and the power grid equipment information retrieval and extraction efficiency isimproved.
