Saving of Energy through Regenerative Braking in Railway Traction Vehicles

We study energy-storage equipment that is connected to chopper of diesel locomotive or traction motor. We take reference model of diesel locomotive for the study of paper. During the powering period, the acceleration of the train becomes larger due to the boosting operation of the equipment. The equipment charges a part of regenerated energy when it boosts the voltage during braking period, and discharges the stored energy when it used to operate other electrical equipment. At the time of regenerative braking we store the electrical energy it is help to save the energy. In this paper, we selected battery bank or super or ultra-capacitor for the energy storage device of the equipment.
