Abstract

The invention relates to the technology of topology analysis in the field of an electric power system, and specifically relates to a method for rapid topology analysis and the establishment of a topological island based on a graph theory. The method includes three steps: modeling, generating topology points, and generating the topological island. According to the method, topology analysis of the electric power system can be conducted via a graph theory recognition analysis method; advantages and disadvantages of breadth and depth first search algorithms can be comprehensively considered, and search advantages of depth first for a ring network are fully used; rapid topology analysis of the electric power network and the establishment of the topological island are realized, and the accuracy and rapidity of the topology analysis result of the electric power network are greatly improved.

Description

technical field [0001] The invention relates to topology analysis technology in the field of electric power system, in particular to a fast topology analysis based on graph theory and a method for establishing topology islands. Background technique [0002] With the operation and development of the power system, the scale of the power network is getting larger and larger. Facing the large-scale power grid structure, it is difficult for the power system dispatching department to judge and deal with power system problems in a timely manner. Therefore, various power system analysis software has been developed. The application of these analysis software solves this problem very well. [0003] Power system topology analysis plays a vital role in power grid operation control and analysis and calculation. It provides basic network structure data for advanced applications of power system analysis software such as state estimation and power flow calculation. At the same time, real-ti...
