2F24 Advantages and Technical Issues on Regenerative Brake All over the Speed Range Method(Vehicles-Rail/Wheel)

抄録

In this paper, the authors propose "regenerative brake notch" which follows the maximum regenerative brake force according to vehicle speed. This specially designed brake force reference selected by the train driver aims at saving kinetic energy which would be dissipated by the frictional brake in the higher sped range. By means of the regenerative brake notch, much kinetic energy is to be saved but the section in which the brake is applied to stop the train is slightly prolonged. Another drawback of the regenerative brake notch is how the driver is informed where to apply the regenerative brake notch, because the regenerative brake notch does not generate constant regenerative brake force over the all speed range. To cope with this problem, the authors propose that the driver is informed where to apply the regenerative brake notch based on the train location information obtained by a preinstalled train information control system (TICS). By means of this method, only the point that the driver start to apply the brake is required and the driver can regulate the brake force in the lower speed range to stop the train within the designated range at the station. In this paper, energy saving effect by the regenerative brake notch is compared with the conventional constant deceleration brake notch. In addition, the deterioration of the energy saving effect is also evaluated when the points to apply the regenerative brake notch is displace to closer points to the stop points and apply stronger brake in lower speed range. Through the calculation study, the energy saving effect and usefulness of the proposed regenerative brake notch is revealed.
