Embodiment Construction

[0035] In order to better understand the technical content of the present invention, specific embodiments are provided below, and the present invention is further described in conjunction with the accompanying drawings.

[0036] see Figure 1 to Figure 5 , a typical wiring pattern recognition method for medium-voltage lines based on feature extraction, including the following steps:

[0037] S1. Select the line to be analyzed, and extract the structural features of the line to be analyzed. The structural features of the line to be analyzed include:

[0038] S11. Starting from any substation exit, obtain all stations and switches on the main line in the line to be analyzed, and according to the distance between the stations, the switches on the column and the exit of the substation from near to far sequentially numbered;

[0039] S12. Establish the connection mode set m of the i-th trunk line i =(K i , t i ), where K i Represents the set of stations and pole switches of t...

Abstract

The invention provides a medium-voltage line typical wiring mode identification method based on feature quantity extraction, and the method comprises the following steps: S1, selecting a to-be-analyzed line, and extracting structural features of the to-be-analyzed line; S2, extracting typical features in the to-be-analyzed line; and S3, according to the typical features, realizing wiring mode identification of the to-be-analyzed line, so that the typical wiring mode of a medium-voltage line can be well identified.

Description

technical field [0001] The invention relates to the technical field of wiring pattern recognition, in particular to a method for recognizing typical wiring patterns of medium-voltage lines based on feature quantity extraction. Background technique [0002] In distribution network planning, grid structure is very important. The wiring mode is the concrete embodiment of the grid structure, which directly determines the power supply capacity, power supply reliability and economy of the wiring group. In recent years, more and more power supply units have put forward the ideas or ideas of automatic planning and automatic network construction, but the premise is that they must be able to automatically and effectively identify the wiring mode of the distribution network. However, in actual work, the wiring mode is mainly Rely on manual identification. Aiming at this problem, a method for identifying typical wiring patterns of medium-voltage lines based on feature extraction is pr...
