在机车车辆牵引系统中，由于其体积小、重量轻、经济性好等优点，往往采用一台逆变器驱动多台并联的异步电动机。采用高压大电流IGBT驱动多台异步电动机的高性能三电平逆变器系统已被广泛采用。另一方面，为了给乘客提供舒适的乘坐感觉，即使在雨天也能保持列车时刻表，需要精确且响应迅速的电机转矩控制。考虑到这种情况，我们已经开发了一种定子磁链定向的矢量控制方法的机车车辆牵引系统，其中一个逆变器给多个感应电动机。在这里，我们新开发了一种新的矢量控制方法，可以提高牵引系统的稳定性和电机的转矩响应。我们还评估了所提出的控制方法，通过稳定性分析，仿真和实验。本文介绍了这种控制方法的原理和机车车辆牵引系统的机械和电气模型，以及稳定性分析，仿真和实验结果。
In the field of the rolling stock traction system, one inverter often drives multiple induction motors connected in parallel, because of its compactness, lightness and economical advantages. A high performance three level invereter system using high voltage and large current IGBTs that can drive multiple induction motors has been widely adopted. On the other hand, in order to provide passengers of comfortable ride feeling and to keep the train schedule even in rainy days, an accurate and responsive motor torque control is demanded. Considering this situation, we have already developed a stator-flux-oriented vector control method for the rolling stock traction system in which one inverter feeds multiple induction motors. Here, we have newly developed a novel vector control method which can improve the stability of the traction system and the motor torque response. We have also evaluated the proposed control method through stability analysis, simulations and experiments. This paper presents the principle of this control method and the mechanical and electrical models of the rolling stock traction system, as well as stability analysis, simulation and experimental results.
