Embodiment 1

[0052] Please refer to figure 2 The first embodiment of the present invention is: a method for modeling distribution network line diagrams, which can be applied to GIS data modeling in distribution network line engineering, including the following steps:

[0053] S1: Obtain standard graphic elements of power grid equipment, that is, standard graphic element data of the State Grid, for subsequent matching and identification of the CAD drawings of the as-built drawings of the distribution network lines. The primitive is the solidification icon of each device, and it is the basic unit of the engineering drawing. In this embodiment, the power grid equipment includes tower equipment, switch equipment, pole transformers, wire equipment, cable equipment, and cable terminal heads, that is, power grid equipment of the distribution network.

[0054] S2: Load the as-built drawing of the distribution network line, and establish a preset coordinate system in the as-built drawing of the distrib...

Embodiment 2

[0072] This embodiment is a specific application scenario of the first embodiment.

[0073] The automatic modeling tool integrates the standard graphic metadata of the national grid distribution network and integrates the CAD image recognition technology.

[0074] After the power grid GIS modelers receive the completed drawings of the distribution network line project, they need to model the project. The modeler opens the automatic modeling tool and imports the as-built drawings. The system uses CAD image recognition technology to compare drawings based on standard image metadata, identify and generate corresponding equipment data and topological relationships, and store them in the database. After the identification is completed, the system draws a project path diagram based on the generated device data and device topology. Modelers check the project path diagram according to the actual situation, supplement missing equipment, specify equipment status, match the original equipme...

Embodiment 3

[0076] This embodiment is a computer-readable storage medium corresponding to the above-mentioned embodiment, on which a computer program is stored, and when the program is executed by a processor, the following steps are implemented:

[0077] Obtain the standard graphic elements corresponding to the power grid equipment, and load the as-built drawing of the distribution network line;

[0078] Identifying the as-built drawing of the distribution network line according to the standard graphic metadata, obtaining a grid equipment graphic, and generating equipment data corresponding to the grid equipment graphic, the equipment data including location information and connected equipment sets;

[0079] Generating a line path diagram according to the equipment data corresponding to the grid equipment graphic and the standard graphic element;

[0080] According to the route diagram, the data in the pre-modeling area is edited.

[0081] Further, the power grid device graphics include point devi...

Description

Technical field [0001] The invention relates to the technical field of power grid modeling, in particular to a method for modeling a circuit diagram of a distribution network and a computer-readable storage medium. Background technique [0002] Power grid GIS data modelers usually perform modeling operations on the power grid GIS based on the completed drawings after receiving the project completion drawings from the design unit. However, the modeling of distribution network line engineering usually requires drawing of power grid equipment such as towers, wires, switches, pole transformers, cables, terminals, etc., which are drawn by manual comparison with drawings. The drawing work is cumbersome and greatly increases the workload of modelers. , And drawing errors are prone to occur, and drawing accuracy cannot be guaranteed. Summary of the invention [0003] The technical problem to be solved by the present invention is to provide a modeling method and computer readable storage ...
