Abstract

The invention relates to a method for realizing generation of subblock topology information analysis in a power system on the basis of computer system. The method includes the steps of acquiring and storing power grid connection information and adjacency relation information according to node model of a power system; subjecting a power grid to subblock processing to obtain a power grid subblock cluster and power grid subblock connection relation information; implementing reconstructive processing operation for partial topology information from connection to disconnection of a switch; and implementing reconstructive processing operation for partial topology information from disconnection to connection of a switch. The invention further relates to an above method based entire-network topology information acquisition control method by means of the computer system. The subblock topology generating method and the entire-network topology information acquisition control method for power system can reconstruct partial network via switching changes in partial network, complete the entire-network topology update and can be adaptive to high timeliness requirement of the power system, searching efficiency is improved, system resource is saved, processing process is fast, working performance is stable and reliable, and application range is wide.

Description

technical field [0001] The present invention relates to the field of power system network control, in particular to the technical field of power system network topology information analysis and control, and specifically refers to a computer system-based method for realizing the analysis and generation of block topology information in a power system and the corresponding realization of using a computer in a power system. A method for the system to obtain and control the topology information of the entire network. Background technique [0002] In the literature (Wang Xiangzhong, Li Xiaolan, Power grid topology identification based on correlation matrix, Power Grid Technology, 2001, 25(2): 10-16), the author proposed the correlation matrix method by using assembly language to develop a method that can identify 64 nodes × 64 branches However, it is far from enough for the situation that the current power grid often has thousands of nodes and branches. In the literature (Zhu Bin...
