Abstract

Abstract:

Path planning for material transportation is the fundamental work for constructing power transmission line in complex terrain areas. Such paths generally comprise road and ropeway transportation paths. Based on the digital elevation model and Dijkstra algorithm, this study proposed a combined material transportation path planning algorithm for road and ropeway. Using the fast search method of no-load ropeway transportation path based on parabola, a load ropeway transportation path optimization based on catenary was implemented. Then, the road transportation path was optimally searched using Dijkstra algorithm, and the coordinated planning of road and ropeway transportation paths was conducted. The proposed algorithm was applied to the material transportation path planning of an ultra-high voltage transmission line's towers. Results showed that the combined ropeway and road transportation paths can effectively shorten the design period of material transportation path and improve the efficiency of construction material transportation.

Key words: power transmission line, material transportation, path planning, interference point search method, Dijkstra algorithm
