Modeling and Simulation for Electromagnetic Emission of Maglev Train

As a new type of rail vehicle, magnetic levitation (maglev) train has received extensive attention due to its noncontact operation and low running resistance [1]. The maglev system is a complex system integrating high-power electrical equipment and low-power control and signal equipment. Since the maglev train adopts the linear synchronous motor traction power supply mode, the linear current motor with large working current and open space forms electromagnetic field leakage, which is the dominated electromagnetic emission source within the maglev system [2]. With the rapid development and increasing applications of maglev rail technology, it attracts more and more attention on the mechanism how the meglev system will influence on the electromagnetic environment [3].
