Route Planning for Secondary Cable Pipeline Laying in Substation Based on GIM 3D Technology
In response to a series of issues such as the inability of all lines to attach to pipelines during the laying of secondary cable pipelines in substations,a GIM three-dimensional technology based method for the laying of secondary cable pipelines in substations is studied.Firstly,the spatial grid of the secondary cable pipeline route planning is gridded using GIM three-dimensional technology and the spatial nodes of feasible routes are drawn.Then,the difference in pheromones between paths is measured using ant colony algorithm.Finally,the worst-case path is eliminated to complete the optimization design of the laying path.The experimental results show that by introducing a gravity attraction model in the GIM three-dimensional space environment,the spatial posture of the cable line during laying is more realistic,and the cable line is also completely attached to the pipe wall,avoiding contact with obstacles,indicating that this method has good cable laying planning ability.
