Urban Rail Transit Energy Storage Based on Regenerative Braking Energy Utilization

Abstract

In order to better realize the energy-saving operation of urban rail transit trains, considering the use of regenerative braking energy has become the focus of current academic research. Train operation chart optimization, energy storage system recovery, and inverter system feedback are the main technical means for its implementation. At present, the recovery of energy storage systems includes super capacitor type, battery type, and flywheel type energy storage devices. This paper focuses on the urban rail transit energy storage recycling method based on the utilization of regenerative braking energy, studies the basic working principle of the energy storage recovery device, and analyzes the different energy storage and recovery devices, and draws conclusions through comparison.
