Research on Rail Transit Wireless Power Transmission System Planning Based on Particle Swarm Optimization Algorithm
Research purposes:The wireless power transmission(WPT)technology for rail transit is in rapid development.Before large-scale engineering application,there is a lack of systematic research on how to configure the"power"of the line and the charging strategy.To improve the economy of the whole project and achieve the optimal cost of construction and operation,the distribution planning has a systematic nonlinear problem,which has the characteristics of multi-dimension,multi-objective,multi-constraint and multi-variable.Research conclusions:(1)The particle swarm optimization(PSO)is selected as the optimization algorithm for calculation from the aspects of static and dynamic power supply coordination,dynamic guide length and device capacity selection.(2)Firstly,the nonlinear mathematical model is built with the constraint conditions,distribution system planning and scheme selection criteria.Finally,the feasibility is verified by the simulation solution of an example.(3)The algorithm has excellent global optimization capability in the planning of rail transit WPT system.
