Title:
POWER GRID DISTRIBUTION NETWORK FRAME TOPOLOGY CONSTRUCTION METHOD BASED ON POWER DISTRIBUTION AND UTILIZATION HOLOGRAPHIC DATA MODEL
Document Type and Number:
WIPO Patent Application WO/2024/103968
Kind Code:
A1
Abstract:
The embodiments of the present application relates to a power grid distribution network frame topology construction method based on a power distribution and utilization holographic data model, comprising: acquiring graphic data of a plurality of power grid devices in a power grid PMS system, converting the graphic data into topological data, and writing the topological data into a graph database; on the basis of the graph database, identifying among the plurality of power grid devices a transformer substation node and a plurality of tower nodes that have a connection relationship with the transformer substation node; determining a sag-related parameter on the basis of the distance between each two adjacent towers among the plurality of tower nodes, and constructing a sag line segment function on the basis of the sag-related parameter; and, on the basis of the sag line segment function, drawing an overhead line curve between each two adjacent towers, so as to obtain a power grid distribution network frame topological graph. Therefore, the method constructs a unified topological model by using the graph database and a three-dimensional technology, and calculates and visualizes the three-dimensional topological line sags, thereby improving the operation and maintenance management level.
