Status analysis of regenerative braking energy utilization equipments in urban rail transit

Abstract

This paper introduces the three schemes of regenerative energy utilization in urban rail transit, i.e. the energy dissipation type, the energy storage type and the energy feedback type, and their application status. Comparative analysis of the three schemes is performed from multiple perspectives. Finally, this paper proposes that the line conditions, the vehicle type and other factors should be considered comprehensively when choosing which regenerative braking energy recovery devices should be used. In addition, the economic and technical comparison should also be made. Based on this, a reasonable allocation scheme can be got to achieve good economic benefit.
