And S120, drawing an electrical connection diagram of the medium-voltage circuit based on the topological structure through a Geographic Information System (GIS).

The geographic information system (Geographic Information System, abbreviated GIS) is a spatial information system. The technical system can collect, store, manage, calculate, analyze, display and describe the related geographic distribution data in the whole or part of the earth surface space under the support of computer hardware and software systems.

In the embodiment of the invention, in order to realize efficient drawing of the electrical connection diagram, GIS is adopted, and the electrical connection diagram of the medium-voltage circuit is drawn based on the topological structure of the medium-voltage circuit obtained through analysis. Specifically, the position of the transformer substation in the canvas can be determined based on the contact relation of the medium voltage lines among the transformer substations in the topological structure. For example, according to the density degree of the medium-voltage lines, the position of the transformer substation is determined, and the denser the medium-voltage lines associated with the transformer substation are, the earlier the transformer substation is drawn in a canvas center; the sparser the medium voltage lines associated with the substation, the later the substation is drawn at the canvas edge.

In the vibration wire arrangement process, the GIS system performs wire smoothing, and performs wire connection according to a wire shortest principle, for example, when the substations A and B are connected by wires, a contact switch nearest to the other party is selected in the substations A and B to perform wire outgoing. The line connection is carried out by the line shortest principle, so that the cross overlapping of the lines can be avoided to the greatest extent.

In addition, in the process of drawing the electrical connection diagram, the transformer substation, the circuits and the components are mutually exclusive and occupy the positions of the transformer substation, the circuits are ensured not to overlap, pass through the transformer substation and the components, and the occurrence of the circuit crossing is reduced as much as possible. The connecting lines are all straight lines and right angles turn, if the unavoidable lines are crossed, arc marking is adopted at the crossing points, and the output electric connection diagram is ensured to be concise and visual, and the lines are clear and attractive.

And performing grid layout on the substations B, C and D according to the sequencing result, and drawing the substations. Further, the substation E which has no direct connection relation with the central station a is laid out and drawn.

In this optional embodiment, a specific manner of determining the position of the substation in the canvas and drawing the substation based on the contact relationship of the medium voltage lines between the substations in the topology is provided: in the topological structure of a medium-voltage line, a transformer substation pair with a contact relation is obtained; at least one medium voltage line is arranged between two substations in the pair of substations. And further, based on the number of medium voltage lines between two substations in the pair, determining the position of the substation in the canvas and drawing the substation.

In one specific example, substations A, B, C, D and E are included. According to the connection relation of medium voltage lines among substations in a topological structure, the following substation pairs are determined: there are 10 lines between A and B, 5 lines between A and C, 4 lines between A and D, no line between A and E, and 4 lines between C and E. Firstly, confirming that the substation A with the most connecting lines with other substations is used as a central station, and sorting the substations with direct connection relation with the central station from more to less according to the number of the connecting lines with the central station, namely, the substations B (10 connecting lines with A), C (5 connecting lines with A) and D (4 connecting lines with A). And performing grid layout on the substations B, C and D according to the sequencing result, and drawing the substations. Further, the substation E which has no direct connection relation with the central station a is laid out and drawn. If a plurality of substations are not in direct connection with the central station, the substations are ordered according to the connection line data of the substations and other substations, and the substations are laid out according to the ordering result.

And S240, drawing the medium voltage lines between the substations based on the contact relation of the medium voltage lines between the substations and the positions of the substations in the canvas.

In the embodiment of the invention, after the transformer stations are laid out in the canvas, the medium voltage lines between the transformer stations are drawn further based on the contact relation of the medium voltage lines between the transformer stations and the positions of the transformer stations in the canvas.

After the connection relationship between the substations is completed, the connection relationship between different lines in the same substation needs to be established. Specifically, one transformer substation is sequentially extracted as a current transformer substation, and according to the contact relation, the line information of another line which starts from the current transformer substation and is connected to the current transformer substation is queried, and in-station line connection is performed.

At this time, the connection operation may be repeatedly performed by continuing to return from the line No. 2 of the substation a, and connection of all the connection lines from the substation a is completed.

Further, the transformer substation B is extracted as a current transformer substation, and continues to be connected with the No. 3 wire of the transformer substation E from the No. 1 wire of the transformer substation B, and connected with the No. 5 wire of the transformer substation F from the No. 3 wire of the transformer substation E. And repeatedly executing the operation until the line connection taking all the substations as the current substations is completed.

In addition, when the line connection is performed, the outlet point of the line needs to be selected according to the positions of the two substations to be connected in the canvas. For example, when the line 1 of the substation a is connected to the line 3 of the substation B, the target outlet point of the line 1 needs to be selected in the substation a, and the target outlet point of the line 3 needs to be selected in the substation B. Specifically, among the remaining outlet points of the substations a and B, an outlet point that makes the above-described connection shortest is selected as a target outlet point.
