Advantages and technical issues of regenerative brake method at all over the speed range

In this paper, the authors propose “regenerative brake notch” method which follows the maximum regenerative brake force according to the vehicle speed. This specially designed brake force reference selected by the train driver aims at saving the kinetic energy which originally would be dissipated by...

This specially designed brake force reference selected by the train driver aims at saving the kinetic energy which originally would be dissipated by the mechanical brake in the high speed range. By means of the regenerative brake notch, it is able to save much kinetic energy, but the brake section is slightly prolonged. Another drawback of this method is how to inform the starting braking point to the driver, because this brake system does not generate constant regenerative brake force all over the speed range.
