Embodiment Construction

[0042] like figure 1 As shown, the grid topology configuration method includes.

[0043] S1. Array initialization, clear the node array and branch array.

[0044] S2. Read all power supply, load nodes and feeder segments from the database into the memory to obtain the total number of nodes searched for this time.

[0045] S3. Make an adjacency matrix and store the topological elements, and read the adjacency matrix into a memory array; including.

[0046] 1) Store branch data; use SQL statement to select all branches.

[0047] Read all topology information into the tributary matrix; use the deduplication keyword to read in the connected node related records, and filter out duplicate records at the same time, if you want to connect other devices, use the deduplication key behind the SQL Words are associated multiple times; after all branch data are selected, they are directly inserted into the branch matrix.

[0048] 2) The topology node data is stored; the branch matrix is...

Abstract

The invention discloses a power grid topology configuration method, which comprises the following steps of: initializing an array, obtaining the number of all nodes, generating and reading an adjacent matrix, searching branch nodes after resetting the nodes, searching unprocessed nodes until all the nodes are searched, and outputting a processing result. According to the power grid topology configuration method, topology elements are managed through the adjacent matrix, branch nodes are searched based on the established node branch association table, forward and backward accumulated search is carried out on the branch nodes, and the processing result can be digitally and efficiently output so as to facilitate subsequent node processing.

Description

[0001] This application is a divisional application. The original application is an invention patent titled "A method for configuring a power grid topology". The application number of the original application is "2021100001659", and the application date is January 1, 2021. technical field [0002] The invention relates to the field of power grid maintenance, in particular to a power grid topology configuration method. Background technique [0003] The topology of the power grid is to abstract the equipment, components and lines of the power grid into a graph of symbolic connections for various analysis and calculations. For example, a very complex circuit can be directly represented by a straight line. [0004] The current power grid topology management system is relatively simple to manage the power grid topology, cannot implement vectorized management, and cannot analyze the correlation between nodes and branches, and is also relatively inefficient in large-scale node sear...
