目前国内对于旅客捷运系统(Automated People Mover,简称APM)牵引供电系统理论研究尚未成熟,为辅助新建APM线,在分析现有APM牵引供电系统的基础上,利用Simulink软件对其外部电源、牵引变电所、三相接触轨及车辆等组成部件进行建模。对比分析列车正常运行和过负荷运行时接触轨上线电压分布情况,验证所建立的APM交流牵引供电系统仿真模型的正确性。仿真分析两列车同时运行时,不同追踪距离对系统电气特性的影响情况。分析单变电所退出运行时接触轨上电压分布情况,验证系统供电的安全性和可靠性,可为APM前期供电方案的设置及选择提供依据。
Abstract
At present, the theoretical research on APM (Automated People Mover) traction power supply system is not mature in China. In order to assist in the design of new APM line, based on the analysis of the existing APM traction power supply system, Simulink was used to model the components of its external power supply, traction substation, three-phase contact rail and vehicle. The voltage distribution of contact rail during normal operation and overload operation of the train was compared and analyzed to verify the correctness of the established simulation model of APM AC traction power supply system. The simulation analyzed the influence of different tracking distances on the electrical characteristics of the system when two trains were running at the same time. The voltage distribution on the contact rail when the single substation was out of operation was analyzed, and the security and reliability of the system power supply were verified, which provided the basis for the setting and selection for the APM pre-power supply scheme.
