Abstract

The invention discloses an analysis method and device, a storage medium and a processor of a power grid power flow. Wherein, the method includes: transforming the power grid graph into a calculation graph model, wherein the calculation graph model is composed of nodes and edges, the nodes are used to represent the nodes in the power grid system, and the edges are used to represent the lines in the power grid system; the calculation graph model is detected type; according to the type, select the method corresponding to the type to perform power flow analysis on the power grid. The invention solves the technical problems in the prior art that the relational database is used, the response speed is slow and the structure is redundant and complicated, so that the topology analysis of the large-scale power grid cannot be quickly realized.

Description

technical field [0001] The present invention relates to the field of power grids, in particular to a power grid power flow analysis method and device, a storage medium, and a processor. Background technique [0002] Grid Geographic Information System (Geograph Information System, referred to as Grid GIS), as a spatial information technology, is a computer system used to collect, store, manage, analyze, display and apply geographically related data. At present, the power grid GIS system uses the Oracle spatial database storage technology. For the power grid topology of the full voltage level, this storage method and technology has calculation and processing bottlenecks in relational calculation, search, and tracking. [0003] In the related technology, the maintenance and use of power grid GIS has adopted Oracle database for relational storage, and the current graph relationship of GIS1.6 seriously restricts the rapid mapping of graph models based on graph database and graph...
