一种基于快扫描的牵引供电系统运行仿真方法

One Simulation Method of Traction Power Supply System Operation Based on Rapid Scanning

基于Matlab建立了一种城市轨道交通直流牵引供电系统的仿真方法,采用快扫描的方式不断地对仿真模型进行参数修改和调用,完成了对直流牵引供电系统的仿真。该方法不仅对牵引计算进行了统筹考虑,基于最快牵引策略进行了牵引计算,而且建立的牵引变电站的仿真模型是基于新型能馈式脉冲整流器,为城市轨道交通的新建和扩建提供了一种分析方法。

In this paper, a simulation method of urban rail transit DC traction power supply system has been established based on Matlab, this method uses quick scan approach to change the parameters of the model and calls the model continuously, and then completes the simulation of DC traction power supply system. This method not only takes traction calculation into consideration, but also establishes a simulation model of traction substation based on a new-type feedback PWM rectifier, it provides a way of analysis for new and expanded urban rail transit.
