Abstract: The high-speed maglev trains have obvious advantages in long-distance operation. For the analysis of vehicle operating performance, it is very important to establish the system simulation model with multiple traction zones. A simulation model of multiple power supply zones adopting dual-terminal power supply was established based on MATLAB / Simulink, which included three sets of inverters and two linear motors. A speed current dual-loop control strategy was adopted. Under the conditions of the converter capacity 24 MVA in the acceleration stage and the deceleration of 1 m / s² in the braking stage, the traction performance of vehicle in long distance was simulated based on this model. The results show that the traction power supply zones of the model can switch smoothly using real-time current allocation methods of both same output voltage and near end converter full load, realizing the simulation of long-distance and verifying the effectiveness of the model.
