Modeling of Traction Transmission System for Urban Rail Transit

作为城市轨道交通牵引供电系统的核心--机车牵引传动系统,对其进行合理的建模研究具有极其重要的意义。搭建了机车牵引传动系统模型,对牵引和制动特性进行分析,采用2C4M架控驱动方式,重点对牵引传动控制系统进行建模,给出了详细的转速控制器和基于转子磁场定向的矢量控制方法 ,并根据某线路的实际参数,计算交流机车负载转矩。最后通过计算结果与仿真结果的对比,验证了牵引供电系统模型及控制策略的正确性。

As the core of traction power supply system of urban rail transit traction drive system, it is of great signifcance to carry out reasonable modeling. This paper sets up the model of the transmission system of the locomotive traction, traction and braking characteristics are analyzed, using 2C4M frame control drive mode, focus on the modeling of the traction control system, gives a detailed and speed controller based on rotor feld oriented vector control method, and according to the actual parameters of a line, calculates the AC locomotive load torque. Finally, the calculation results and simulation results verify the correctness of the traction power supply system model and control strategy.
