Research On Optimization Of Urban Power Network Laying Route

As the city power distribution,power cable carriers get down from ground to underground during the city development,and get more standard in channel laying form the overhead laying.The optimal path selection of power cable is particularly important in the process of laying power network in city power network construction.How to make use of limited city power network construction has become one of the important research topic in the city of cable laying,because of cable laying has becoming more complex than ever.This paper is studied for laying method optimization in the laying progress of power network based on the shortest route with ampacity optimization,and the main contents of this paper are as follow:(1)The specific installation of the power network and the influences of ampacity in laying process are analyzed based on the problem of optimization of urban power network laying route.And the mathematical model is established of power distribution network combined with the power network base information.(2)The relationship between the ampacity and temperature field are analyzed,and calculation methods are studied in the different installation scenarios.The influence of temperature field are further studied,and the ampacity are calculated by analytical method and finite element method.(3)The model of cable laying route is fixed by ampacity optimization,and ampacity optimized cable laying model is proposed.Ant colony algorithm is studied and improved,and the algorithm is applied to the final comparison simulation,to prove the superiority of the algorithm.(4)Effectiveness of applicability is verified in the ampacity optimized cable laying model,and the simulation in comparison is carried out under a single point of laying and multipoint laying scenarios.Function module is designed and cable laying system is developed according to the verification results of cable laying methods,and the theoretical research results are applied.
