Abstract

At present, in order to alleviate environmental problems and energy crises, fuel cells are gradually being used in rail transit vehicle (RTV) drive systems. However, in the existing fuel cell drive systems, DC/DC converters are widely used, but there are serious shortcomings in terms of cost, efficiency and market application. To solve these problems, a novel dual-source drive system is innovatively presented in this study. In the dual-source drive system, the multi-mode operating state of the dual source motor was taken into consideration, and based on the independent vector control method (IVCM), the dual-source drive system was modelled and simulated to achieve the motor independent control between power output and power generation as well as the energy exchange between fuel cell and secondary power battery under any working conditions. In order to verify the effectiveness of the proposed dual source drive system, the electric drive performance test was carried out by the dual source system experimental verification platform. The result of this drive system topology is further improved compared with the same level of DC/DC drive system configuration used for this purpose.

基于双源电机的轨道交通车辆燃料电池驱动系统

目前，为了缓解环境问题和能源危机，燃料电池正逐步应用于轨道交通车辆驱动系统。然而，在现有的燃料电池驱动系统中，DC/DC变换器得到了广泛的应用，但在成本、效率和市场应用方面都存在严重的不足。为了解决这些问题，本研究创新性地提出了一种新型的双源驱动系统。在双源驱动系统中，考虑了双源电机的多模式运行状态，基于独立矢量控制方法(IVCM)，对双源驱动系统进行了建模和仿真，实现了在任意工况下电机输出与发电之间的独立控制以及燃料电池与二次动力电池之间的能量交换。为了验证所提出的双源驱动系统的有效性，利用双源系统实验验证平台进行了电驱动性能测试。与用于此目的的相同级别的DC/DC驱动系统配置相比，该驱动系统拓扑的结果进一步改善。
