Embodiment Construction

[0041] Such as figure 1 As shown, a grid topology configuration method includes.

[0042] S1. Initialize the array, clear the node array and the branch array.

[0043] S2. Read all the power supply, load nodes and feeder segments from the database into the memory to obtain the total number of nodes searched this time.

[0044] S3. Make an adjacency matrix and store it into topological elements, and read the adjacency matrix into a memory array; including.

[0045] 1) Store branch data; use SQL statements to select all branches.

[0046] Read all the topology information into the branch matrix; use the deduplication keyword to read in the related records of the connected nodes, and filter out duplicate records at the same time. If you want to connect other devices, use the deduplication key after the SQL Words are associated multiple times; after all the branch data are selected, they are directly inserted into the branch matrix.

[0047] 2) Store topological node data; use...

Abstract

The invention discloses a power grid topology configuration method. The method comprises the 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, the topology elements are managed through the adjacency matrix, branch node searching is carried out based on the established node branch association table, forward and backward accumulationsearching is carried out on the branch nodes at the same time, and a processing result can be digitally and efficiently output so as to facilitate subsequent node processing.

Description

technical field [0001] The invention relates to the field of power grid maintenance, in particular to a power grid topology configuration method. Background technique [0002] The power grid topology is to abstract the equipment, components and lines of the power grid into a graphic of symbolic connections for various analysis and calculation. For example, a very complicated line can be directly represented by a straight line. [0003] The current power grid topology management system is relatively simple to manage the power grid topology, and cannot realize vectorized management, nor can it analyze the correlation between nodes and branches, and is relatively inefficient in the search strategy for large-scale nodes. Contents of the invention [0004] In order to solve the above defects and deficiencies in the prior art, the present invention provides a power grid topology configuration method, comprising: [0005] S1. Initialize the array, clear the node array and the b...
