Automatic Design Method of Cable Laying Path in Substation

In order to improve the efficiency and design quality of substation cable laying, and support the development of digital business, this problem research realizes the automatic design of substation cable laying through the principle of Dijkstra algorithm. This paper adopts the idea of partition grouping, and divides the substation into the same room, the same floor, the same building, indoor and outdoor areas, so as to reduce the number of path screening and reduce the calculation amount. Through the Dijkstra algorithm, the optimal cable laying path of the equipment at any starting point and end point can be calculated, and the cable laying length can be obtained to effectively support the automatic design of the substation.
