Simulation of ground rheostatic braking in mid-to-low speed maglev train

Regenerative braking has been applied widely in the DC power supply system of urban rail transit. However, as a new mode of transportation, there is no existing research on maglev train. The paper explains the simulation model of traction between mid-to-low speed maglev train and power supply system in detail, and provides regenerative braking simulation computation method through adopting ground resistance as energy consumption. With the combination of the reality of maglev S1 project in Beijing, it obtains the work situation of the train during regenerative braking, and explores the setting of braking resistance capacity. The result indicates that the normal working of ground braking resistance could stabilize the network voltage in the reasonable working range effectively. As a result, it could avoid the failure of regenerative braking and assure the normal operation of electrical equipment.
