The design of regeneration braking system in light rail vehicle using energy-storage Ultra-capacitor

Abstract

After analyzed the running mode of city light rail vehicles, the author expounds the necessity of using energystorage regeneration braking system. Then this paper puts forward a new regeneration braking system using Ultracapacitor as energy storage element. The system uses bidirectional converter between Ultra-capacitor and traction inverter DC link, to make sure that capacitor can store the energy produced by regeneration braking system when the general regeneration braking can not be achieved, and provide energy to traction inverter DC link when vehicle is working in the traction condition. In this case, it can ensure that light rail can realize the regenerative braking in the conventional braking, and the light rail vehicle reduces the energy consumption obviously.

Energetic Optimization of the Use of Battery Shunting Locomotive in Industrial Plant with Regenerative Brake

“…Batteries work based on the following principle: due to reversible chemical reactions that occur at the electrodes, a potential difference appears between them. Consequently, energy can reversibly change from electrical form to the chemical form [4], [14], [15]. The Lead-Acid battery is unpretentious to the charge current and for short periods can resist larger circuit currents.…”
