地铁双边供电系统建模与仿真

Modeling and Simulation of Metro Bilateral Power Supply System

对地铁供电系统进行了建模与仿真,重点对直流接触电网及列车负载进行了建模。前者能随列车运行距离而实时变化;后者利用电机角速度作为变量来反映运行过程中负载的变化。这两点保证了仿真模型的有效性和实时性。利用PSB/MATLAB搭建了上海轨道交通2号线系统仿真模型,仿真结果与实测曲线基本一致,证明该模型真实可靠。

A simulation model of metro traction power sup-ply system is presented In this paper, which puts more em-phasis on the modeling of DC network and traction load. DC network model has a real-time respond to the running distance, and the traction load model uses motor angular velocity as a variable to reflect the load changes in running process, these two aspects will guarantee the availability and real-time of the model. By using PSB/MATLAB, a model of Shanghai metro Line 2 is established, and the simulation results are in accordance with the measured curve, it shows that this model is useful and reliable.
