Problems solved by technology
In addition, when the third rail is used for power supply, the power supply is carried out independently and is not controlled by the operation control system, so the timing of power supply is difficult to grasp, so the current solution is to set the third rail to always have power, which will cause additional line loss. At the same time, there are security risks

Embodiment Construction
[0052] The core of the present invention is to provide a ground traction power supply system for maglev trains, which can effectively improve the reliability of the ground traction power supply system for maglev trains, and because the design of the third rail power supply is cancelled in the whole area, the third rail can be avoided. Additional line loss during power supply, and there is a safety hazard.
[0053] In order to make those skilled in the art better understand the solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are only some, but not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

The invention discloses a maglev train ground device and a ground traction power supply system and method thereof, and is applied to the technical field of rail transit. A traction control system; the first traction device is arranged in the main line area and used for receiving the alternating current provided by the traction control system, converting the alternating current, performing traction on the maglev train and enabling the maglev train to obtain power supply through induction of a power generation coil; the current transforming devices are arranged in the main line area and the maintenance area and are used for performing current transforming control in a first mode when receiving a first instruction sent by the operation control system so as to output alternating current to a stator winding, so that the maglev train is powered; and when a second instruction sent by the operation control system is received, variable current control in a second mode is carried out, so that alternating current is output to the stator winding to carry out traction of the maglev train. According to the scheme, the reliability of the ground traction power supply system of the maglev train can be improved, and third rail power supply is canceled in the whole area.
Description
technical field [0001] The invention relates to the technical field of rail transportation, in particular to a ground device of a maglev train and a ground traction power supply system and method thereof. Background technique [0002] At present, the more mature high-speed maglev trains are normally conducting electromagnetic levitation trains and superconducting electric levitation trains. The reason why it is called "Maglev" is that when running at high speed, the vehicle does not have any contact with the track, and relies on electromagnetic thrust as a traction force to drive the train to run. Since the train does not have any contact with the track, how to solve the problem of the power consumption of the train has become the object of research. At present, high-speed maglev trains use two power supply methods: direct power supply from the third rail and linear induction power supply according to different regions. [0003] For the traction of the train, at present, t...
