城市轨道交通牵引系统仿真技术研究

Study of Simulation Technology for Traction Power System of Urban Rail Transit

摘要:

回顾了国内外城市轨道交通系统仿真技术的发展现状,详细阐述了现有仿真系统存在的模型建立不够精确、列车与供电系统间的相互影响考虑不全面等问题导致仿真结果与实际偏差较大的特点,并从车辆与牵引供电网电气交互的角度仿真分析了列车的运行特性,说明牵引网电压变化对车辆牵引性能的影响,最后指出为研究城轨系统的实际运行特性,应进行车网结合的多列车、多工况动态联合仿真,同时还应开展通用仿真平台的研究,并提出使用PSCAD/EMTDC与MATLAB集成作为仿真开发平台.

Abstract:

This paper first reviews the development status of domestic and international simulation technology for urban rail transit system,and describes in detail the shortcomings of existing simulation systems such as less accurate models and incomprehensive consideration of the interaction between train and traction power system,leading to large deviation of simulation result compared with practical experiment.Simulation of electrical interaction between train and traction system shows that the traction performance of the train is influenced by the variation of overhead line’s voltage.Finally,in order to have a fullscale reflection on the characteristics of urban rail transit system that dynamic simulation which combines multitrain with multiworking mode is demanded,and the study of a general simulation platform should also be carried out.It is proposed that the integration of PSCAD/EMTDC and Matlab can be used for developing the platform.
