该文提出了磁悬浮列车低速运行时车载电源供电的新方法。通过在地面定子线圈中注入高次谐波电流和在列车的磁极上加绕一组直线发电机线圈,实现磁悬浮列车在低速运行时车载蓄电池的充足供电。建立了车载直线发电机输出电压模型,研究了车载发电机输出电压与地面定子线圈中注入的谐波电流幅值和频率的关系,并进行实验研究。理论分析和实验结果初步表明了注入高次谐波电流非接触供电方法的可行性。
This paper presents a new method of supplying power to a vehicle-mounted power supply for a low-speed maglev train. By injecting harmonic currents into the stator coils of the ground and winding a set of linear generator coils around the magnetic poles of the train, sufficient power supply of the vehicle battery can be realized when the magnetic levitation vehicle runs at low speed. The output voltage model of the vehicle linear generator was established. The relationship between the output voltage of the vehicle generator and the amplitude and frequency of the harmonic current injected into the stator coil on the ground was studied and experimentally studied. The theoretical analysis and experimental results show the feasibility of the non-contact power supply method of high harmonic current injection.
