摘要
为了满足车辆供电的要求,在现有高速常导磁浮列车车载供电方式基础上,提出了一种新的用于高速磁浮车辆上的冗余供电方法。通过蓄电池供电与感应线圈供电相结合的方式,减少了地面供电设备数量。在每节车辆上设置多个车载电网、每个电网上并联接多个相同的供电设备同时向车辆用电设备供电。通过供电系统的多重冗余设计保证车辆供电的可靠性。该方法满足任意单一供电设备或一定分布的多个供电设备的故障都不会影响车辆的正常运行,即使在任意一个电网整体失效的情况下也能保证列车安全停车到预定的停车位置。
On the basis of present high speed maglev technology, a n ew redundancy power supply system used on high speed maglev train is provided. The quantity of ground power supply equipments are reduced by the combination power supply of battery and inductive coils. There are several onboard power nets in each vehicle, and several identical power devices connected to a same power net in parallel to supply power to the onboard electric equipments. And the reliability of the power supply system is guaranteed by the multi redundancy design. This power supply method ensure that the failure of any single power supply equipment or a certain distribution of several power supply equipments will not affect the normal operation of the vehicle, and it can also ensure the train arrives at a stopping point even under the condition that one onboard power net fails.
