Discuss and Analysis on Regenerative Braking of EMU Based on Matlab

For ordinany generators,we can enter the speed directly through the shaft,thus the rotor speed is independent of the mechanical parts of generators and is only related with the speed of dragging motor;and also enter the torque through the shaft,thus the rotor speed is determined by the rotorinertia,mechanical friction,electromagnetic torque and other factors.The regenerative braking process of EMU should contain the above two situations,so this paper establishes the traction motor's regenerative condition model which can enter the speed and torque at the same time,to analyze the regenerative braking process of EMU.
