Description
Technical Field
The invention relates to the technical field of power supply and operation control of a magnetic-levitation train.
Background
The magnetic suspension train is a rail vehicle which utilizes electromagnetic force to offset the dead weight of the train to realize suspension, has the advantages of strong climbing capability, small turning radius and the like, and has good application prospect in urban and intercity rail transit transportation systems.
The magnetic suspension train is driven by a long stator and a short stator. The long stator type magnetic suspension train is driven by a long stator linear synchronous motor, namely, three-phase alternating current windings of a motor stator are laid on two sides of a ground line and are provided with a power supply by a converter (variable frequency and variable voltage) arranged in a ground substation, and a ground running center controls the running of the train through the synchronous control of the synchronous motor. Its advantages are high power of ground synchronous motor, no mechanical contact between magnetic suspension train and long stator line, and high speed running. The magnetic suspension train with the short stator mode arranges the three-phase windings of the linear asynchronous motor stator on the train (on two sides), and compared with the long stator mode in which the three-phase windings of the motor stator are laid on two sides of a ground line, the three-phase windings of the stator on the train are much shorter, and the short stator mode is famous. The asynchronous motor rotor in the short stator mode is composed of a very thin aluminum plate laid on a line (corresponding to the position of a stator on a vehicle), and the structure is very simple, so that the manufacturing cost of the short stator magnetic suspension line is far lower than that of the long stator magnetic suspension line. This is also a significant advantage and a major reason for the popularity of short stator magnetic levitation trains. However, short stator maglev trains also have significant drawbacks, above all with respect to power supply and current collection: because the motor winding of the short stator maglev train is on the train, the converter (frequency conversion and voltage transformation) for providing power supply must be installed in the train, and needs to be supplied with power from the ground, while the existing mode is that the ground power supply rail and the on-train collector shoe are contacted to complete the power supply and current receiving of the on-train converter, the fluctuation and vibration of the train can seriously affect the contact performance, thereby affecting the current receiving performance, and the influence is larger when the train speed is higher, therefore, although the short stator mode has low manufacturing cost, the short stator mode is not suitable for high-speed occasions. In order to solve the technical problem, the applicant reports 'a three-phase power supply and collection device for a maglev train' with application number 201810660427.2, which can solve the adverse effect of train fluctuation and vibration on current collection performance, make best use of advantages and avoid disadvantages, enable the short stator driving maglev train with low cost to be competent for a high-speed line, and create higher cost performance. Secondly, the problems of the self weight and the bearing efficiency of the train are solved. After the section shape of the suspension rail is determined, the suspension capacity of the vehicle-mounted suspension magnet in unit length determines the total bearing capacity of the magnetic-levitation train, obviously, when the total bearing capacity is fixed, the smaller the self weight of the magnetic-levitation train is, the larger the passenger carrying capacity is, and the higher the bearing efficiency of the magnetic-levitation train is. Therefore, the self weight of the magnetic suspension train must be reduced to improve the bearing efficiency. The optimization of the structure of the vehicle-mounted equipment and the reduction of the weight of the vehicle-mounted equipment are one of effective methods for reducing the self weight of the maglev train and improving the bearing efficiency. The vehicle-mounted equipment is mainly characterized by comprising a traction inverter and auxiliary electric equipment, wherein the weight of the vehicle-mounted equipment is the main weight of the vehicle-mounted equipment, and the noise of a cooling fan of the vehicle-mounted equipment is also the main noise of the vehicle-mounted equipment.
The technical problem to be solved at present is that the system structure is optimized by changing the power supply mode of the system, on one hand, the weight of the vehicle-mounted equipment can be reduced, the bearing efficiency is improved, and on the other hand, the ground control and unmanned driving of the running of the magnetic suspension train can be realized.
