Load process simulation and optimization design of APM traction power supply system

APM是一种立体交叉的、无人驾驶的轨道交通系统,常用于承担大型机场旅客运输任务。目前国内关于APM牵引供电系统仿真的研究相对较少,为辅助设计新建机场APM线,以常见的胶轮路轨制系统为例,研究列车牵引计算方法,并对牵引供电网络进行潮流分析,为APM牵引供电系统提供设计依据;为降低供电轨有功功率损失,提高电能的利用率,建立供电轨功率损失最小化模型,采用粒子群优化PSO算法对牵引变电所位置设置进行优化设计。实验结果表明,本文所述方法能有效实现APM牵引供电系统优化设计的目的,具有较强的工程应用价值。

APM is a three-dimensional,driverless rail transit system that is usually used to undertake passenger transport tasks in large airports.At present,there are relatively few researches on APM traction power supply simulation in China.In order to assist the design of new airport APM lines,taking common rubber wheel track system as an example,the traction calculation method of trains was studied,and the power flow analysis of traction power supply network was carried out,which provides design basis for the APM traction power supply system.In order to reduce the active power loss of power supply rail and improve the utilization of electric energy,the power supply rail power loss minimization model was established,and the PSO algorithm was used to optimize the position setting of the traction substation.The test results show that the method described in this paper can effectively realize the optimization design of APM traction power supply system and has strong engineering application value.
