[0051] The following is combined with Figure 1-3 This application is described in further detail.

[0052] The present application embodiment discloses a power distribution wiring method. Figure 1 , a power distribution wiring method, comprising the following steps:

[0053] S1. Obtaining a collection of GIS geographic information of the area to be planned;

[0054] GIS geographic information includes: any one or more combinations of roads, bridges, tunnels, mountains, lakes, and rivers. In practice, distribution network lines cannot cross lakes and rivers at will, so the shapes and relative distances of roads, bridges, tunnels, mountains, lakes, and rivers and other geographic information should be marked in the area to be planned. Of course, some areas to be planned may not actually have any one or more of roads, bridges, tunnels, mountains, lakes, and rivers. In other words, GIS geographic information includes: any one or more combinations of roads, bridges, tunnels, mountains, lakes, and rivers. Using the atlas of GIS geographic information to implement distribution line planning can coordinate line planning with actual needs and reduce manual workload.

[0055] S2. Obtain an atlas of substations in the area to be planned;

[0056] S3, obtaining a user load atlas of the area to be planned, and grouping the user loads according to the user load atlas to obtain a plurality of user load groups;

[0057] The specific method of grouping user loads according to the atlas of user loads includes: grouping user loads according to the distance between user loads according to the atlas of user loads, and the average total load of each user load of each user load group is less than the preset calibrated total load. Grouping user loads based on the distance between user loads can further reduce the distance and difficulty of wiring, thereby achieving the effect of saving costs and reducing the difficulty of implementation. In addition, limiting the average total load of each user load group can average the power pressure and protect power facilities, while reserving load capacity space for subsequent increases in the total power load in the future.

[0058] S4. Set up a transformer for each user load group and generate a transformer atlas for the area to be planned;

[0059] Specifically, it includes: setting the transformer of corresponding capacity according to the total load of each user load group, and the total load of the user load group is 50%-70% of the rated capacity of the transformer of the load group, so that the power facilities match the power usage and provide guarantee for the stable transmission of power. At the same time, the total load of the user load group is 50%-70% of the rated capacity of the transformer of the load group, so that the transformer can not only ensure the stable transmission of power, but also improve the applicability of power equipment, and avoid the phenomenon of frequent replacement of transformers due to the increase of power load.

[0060] S5. According to the atlas of the substation, the atlas of GIS geographic information and the atlas of the transformer, a main connection diagram of the substation and the transformer is planned;

[0061] Specifically, the substation and transformer are marked as nodes, and the main network connection diagram is generated through the minimum spanning tree algorithm. The distance between the substation and the transformer and the distance between the adjacent transformers are calculated, and the shortest path is selected after comparison and summarized into the main network connection diagram. The minimum spanning tree algorithm is used to quickly plan the lines of the substation and the transformer of each user load group, and effectively avoid the repeated laying of cables, reduce the wiring length, and save wiring costs.

[0062] And the route is planned based on GIS geographic information. If the GIS geographic information includes one or more of roads, bridges, tunnels, mountains, lakes, and rivers, these GIS geographic information can be divided into objects that can be extended and objects that cannot be crossed. For example, in practice, it is possible to follow roads, bridges, tunnels, and rivers, bypass mountains and lakes, that is, to circle around the edges of mountains and lakes instead of crossing mountains and lakes. When the computer performs various possible plans, various plans can be compared to plan the main vein connection diagram.

[0063] S6. According to the atlas of GIS geographic information, the atlas of user loads and the atlas of transformers, a sub-network connection diagram of the connection between the transformers and each user load in each user load group is planned;

[0064] Specifically, the transformers and user loads in the user load group are marked as nodes, and a secondary network connection diagram is generated through the minimum spanning tree algorithm. The distances between the transformer and the user load on different routes and the distances between the adjacent user loads on different routes are calculated, and the shortest path is selected after comparison and summarized into the main network connection diagram. The minimum spanning tree algorithm is used to quickly plan the lines of the substation and the transformers of each user load group, and effectively avoid the repeated laying of cables, reduce the wiring length, and save wiring costs.

[0065] S7. Combine the main vein connection diagram and the secondary vein connection diagram to obtain the distribution wiring diagram. Automatically obtain the GIS geographic information, substation information and user load information of the area to be planned, and quickly group the user loads. Then, based on the user load group, set a transformer in each user load group, plan the distribution line between the transformer and the substation to obtain the main vein connection diagram, plan the distribution line between the transformer and the user load in the user load group to obtain the secondary vein connection diagram, and logically carry out two-level planning to achieve the effect of efficient planning of distribution lines. Through the setting of two-level planning, the distribution wiring diagram is more concise and clear, which is convenient for wiring implementation.
