Description

technical field [0001] The invention relates to the technical field of train power supply, in particular to a power supply system, method and device for a maglev train. Background technique [0002] At present, the magnetic levitation train realizes the non-contact suspension and guidance between the train and the track through electromagnetic force, and then uses the electromagnetic force generated by the power supply equipment to drive the train. This enables the maglev train to run normally. [0003] The running speed of the maglev train is obtained under the traction of the electromagnetic force generated by the power supply equipment. The greater the power generation of the power supply equipment, the faster the running speed of the maglev train. The speed of the maglev train is relatively fast, which can reach more than 500 kilometers, but it needs to slow down when passing through caves and tunnels to ensure the safety of the maglev train. Therefore, the speed of th...
