摘　　要：由于轨道交通站与站区间距离较近,列车启动,停止操作频繁,会产生大量的再生制动能量。研究电流回收的目的是为保持供电质量稳定和调节接触网压的波动。采用可逆变结构的飞轮储能技术,能对列车运行中散失的电流进行回收和抑制,有效保障电流传输的稳定和列车运行安全问题。首先,对列车再生制动的工作原理及回流特点进行分析。其次,讨论电流造成钢轨电位升高和杂散电流的危害进行阐述,提出解决和回收电流的技术机理。最后,通过实验总结比较列车运行中的再生制动能量回收和预防电流散失的技术路线和结果。Due to the close distance between rail transit stations,frequent train start and stop operations,it will generate a large amount of regenerative braking energy.The purpose of studying current recovery is to maintain stable power supply quality and regulate fluctuations in contact network voltage.Employing flywheel energy storage technology with a reversible inverter structure,we can effectively recover and suppress the current lost during train operation,ensuring the stability of current transmission and the safety of train operation.Firstly,analyzes the working principle and re-flux characteristics of train regenerative braking.Secondly,discuss the hazards of current causing an increase in rail potential and stray currents;propose technical mechanisms for solving and recovering current.Finally,through experiments,summarize the technical routes and feasible solutions for regenerative braking energy recovery and prevention of current loss during train operation.
