Description

technical field [0001] The invention relates to the technical field of electric power information, in particular to a modeling method and device for a power grid GIS based on a graph database. Background technique [0002] In the power information system, the power grid GIS system records the characteristics of the power grid network. The physical relationship of the power grid, customer relationship, and asset relationship form a huge network topology structure. At the same time, massive power grid operation data, status monitoring data and intelligent Meter data. At present, the power grid GIS system still uses traditional relational databases when processing massive data and providing topology analysis, and has encountered serious technical bottlenecks in many aspects such as query efficiency, storage scale, scalability, and massive data management, which are difficult to overcome. Contents of the invention [0003] The main purpose of the embodiments of the present in...
