Description

technical field [0001] The invention relates to the technical field of high-speed maglev trains, in particular to a high-speed maglev train simulation test system and a test method. Background technique [0002] The maglev train is a train that uses electromagnetic force to suspend the train on the track and is propelled by the electromagnetic thrust of the linear motor. High-speed maglev train is a means of transportation that can fill the speed gap between high-speed rail and airplanes. The speed of high-speed maglev trains usually exceeds 400 kilometers per hour. The high-speed maglev transportation system is composed of four subsystems: line track, traction power supply, operation control, and vehicle. It is a comprehensive system closely related and strongly coupled. [0003] The high-speed magnetic levitation motor is a special long-stator motor. Its mechanism is complex, and the motor stator is different according to the circuit planning. At the same time, the power...

Problems solved by technology

However, this kind of scheme is usually still independently aimed at the performance simulation of a certain subsystem in the train. For example, for the traction system in the maglev train, by constructing the traction control system, traction simulation system and traction simulation management subsystem, the traction control system realizes the traction simulation. The control of the converter and the linear motor in the system, and the data interaction with the traction simulation management subsystem, this kind of method cannot realize the performance simulation test of the whole train, and the semi-physical simulation method is used, and the output train characteristics are The virtual low-power signal, but the actual high-maglev motor has high-power characteristics, so it is impossible to truly simulate the high-power characteristics of the actual high-maglev motor. There will be differences between the simulation results and the actual physical performance, and it cannot truly reflect the performance of the train. , and a large amount of hardware in the platform uses simulators instead of real objects, which will also reduce the scope of system equipment testing and increase the risk of on-site debugging
