Problems solved by technology

[0005] In view of the fact that in the existing technology, the distribution network has a wide range of points, a large scale, a complex structure, many ring network points, and intricate contact relationships, manual analysis of feeder groups requires distribution network single-line diagrams, distribution network ring diagrams, or topological relationships. Classification, screening, division and definition are very inefficient for manual feeder groups and typical wiring groups, and there are problems of low efficiency and low accuracy in the analysis of feeder groups and typical wiring classification

Embodiment 1

[0051] This embodiment provides a typical wiring diagnosis method for a distribution network line, figure 1 For its working process principle, it automatically establishes data interfaces from distribution network single-line diagrams, distribution network ring diagrams and other related systems, obtains graphic files, realizes distribution network single-line diagram image-to-mode conversion, and analyzes distribution network ring network switches and the two sides to which they belong Corresponding to the line and other information, and the information of the ring network switch and the information of the lines on both sides, automatically generate the distribution network information ledger data table. Using the distribution network information ledger data table, the distribution network ring network ledger information is analyzed to form a database; the distribution network feeder group is intelligently analyzed on the database, and the distribution network lines with direc...

Embodiment 2

[0053] A typical wiring diagnosis and analysis method of distribution network lines provided in this embodiment is consistent with Embodiment 1, and the method flow chart is as follows figure 2 shown, including the following steps:

[0054] S1. Establish a data interface from the distribution network single-line diagram and distribution network ring diagram system, obtain relevant data, convert the distribution network single-line diagram to a model, and generate a distribution network information ledger data table;

[0055] S2. Divide the distribution network lines into several feeder groups according to the distribution network information ledger data table;

[0056] S3. Classify each feeder group according to the characteristics, application logic and key information of the typical wiring group;

[0057] S4. Carry out classification and counting of typical wiring groups for the feeder group categories output by S3, make statistics on typical wiring conditions and output d...

Abstract

The invention discloses a typical wiring diagnostic analysis method of a distribution network line. The method comprises the following steps of S1, establishing a data interface from a distribution network single line diagram and a distribution network looped network diagram system, obtaining the related data, performing the distribution network single line diagram analog-to-digital conversion, and generating a distribution network information standing book data table; S2, dividing the distribution network line into a plurality of feeder line groups according to the distribution network information standing book data table; S3, classifying the feeder line groups according to the characteristics, the application logic and the key information of the typical wiring groups; S4, carrying out typical wiring group classification counting on the output feeder line group categories, gathering the typical wiring conditions, and outputting the data; and S5, collecting the data outputted in the step S4 to generate a typical wiring group analysis report. The method has the following advantages that 1, the method reduces the burdens of the planners and basic power supply station business personnel, and has the characteristics of high real-time performance, high accuracy and high efficiency; 2, the category of each feeder group of the distribution network is comprehensively disclosed, and theimprovement of the production operation management level is facilitated.

Description

technical field [0001] The invention relates to the field of distribution network production and operation analysis, and more specifically, to a diagnostic analysis method for typical wiring of distribution network lines. Background technique [0002] In order to improve the reliability of the power supply of the distribution network, in order to avoid the loss of more users when the distribution network fails, the distribution network line is generally segmented by the segment switch, and the ring network point is set to realize communication with other distribution network lines powered by. When various faults occur on the distribution network line, the fault point is isolated by the segment switch, and then the non-faulty area users are quickly restored by closing the ring network point. Therefore, in order to ensure the reliability of power supply for users of distribution network lines, the flexibility of daily production and operation of distribution network racks, an...
