Abstract

The invention aims at providing a rapid construction and analysis method for a power-grid topology relation. The method includes constructing the power-grid topology relation, and performing power-grid analysis and power-grid topology verification according to the power-grid topology relation, wherein constructing of the power-grid topology relation includes constructing of a topology space data structure; the power-grid analysis includes power-grid connectivity analysis, power-grid tracking analysis, power-off-area analysis and power-grid topology verification analysis; and the power-grid topology verification includes verification of subordination relation, inclusion relation and connection relation of electrical devices. The rapid construction and analysis method for the power-grid topology relation is capable of performing topology reconstruction and inspection in a real-time manner. The method not only pays close attention to processing of space data, but also pays more attention to the connection relation of the devices and expression of the power-grid topology and power-grid topology application analysis.

Description

technical field [0001] This patent belongs to the field of power grid management and application. Using the related technologies of geographic information system (GIS), combined with the geographical location information of the power grid, quickly construct the topology model of the power grid, and can check, update and modify the topology relationship in real time, as well as perform conventional power grid topology analysis. Background technique [0002] In power application and management systems, network structure description and topology analysis play an important role, even the cornerstone of many business applications. Early network topology analysis was based on a specific data structure, and its common disadvantages are low efficiency and Poor scalability. When a new device is added to the network or a certain electrical component has new topology characteristics, it cannot automatically adapt well, and a large number of modifications may be required. From the persp...
