Abstract

The invention discloses a power grid sub-graph construction method based on region division, a topology analysis method, a power grid sub-graph construction device based on region division, and a topology analysis device. The power grid sub-graph construction method comprises the following steps: acquiring equipment components and attribute information thereof in a power grid system for establishment as vertex data; dividing the vertex data into a plurality of region vertex sets according to a geographic region attribute of the equipment; acquiring a binary relationship between each two vertices in each region vertex set, and constructing a binary relationship set of each region vertex set according to the binary relationship; constructing a first edge set according to the connection relationship of the equipment components in the power grid system; constructing a second edge set corresponding to the region vertex sets according to the correspondence between the binary relationship setand the first edge set; and constructing a region sub-graph of the power grid system according to the region vertex sets and the second edge set. By implementing the invention to effectively divide the power grid data, the divided sub-graphs are relatively balanced in scale, thereby realizing distributed storage and parallel processing of the power grid data, and improving the efficiency of topology analysis.

Description

technical field [0001] The invention relates to the field of distributed computing of a power grid system, in particular to a method for constructing a subgraph of a power grid based on area division, a topology analysis method and a device. Background technique [0002] In recent years, graph database technology based on "graph theory" has become a new type of data management method and computing model, because it can easily represent the data of the network structure, and has become a massive data storage and computing method with complex relationships. hotspot mode. Due to its inherent network characteristics, the grid system can be identified as a graph, and graph data technology can help simplify the topological connection relationship of complex grid systems. [0003] However, the main advantage of existing graph database technologies, such as GraphX ​​and Neo4j, is the iterative calculation of graph data. Although it is universal for general graph data applications, ...
