城市轨道交通再生制动能量回馈装置容量选择研究

Capacity Selection of Regenerative Braking Energy Feedback Device for Transit

再生制动能量回馈装置应用在城市轨道交通领域,其作用是将列车制动时产生的能量回馈到交流电网,以实现能源的综合利用,达到节能降耗的目的。如何选择再生制动能量回馈装置的容量是决定系统节能效果的重要方面。以国内某城市轨道交通工程为例,采用理论分析与仿真、数理统计的方法,对能量回馈装置的容量选择及不同容量下的节能效果进行对比分析。

Regenerative braking energy feedback device used in the field of rail transit is playing a role to feedback the energy generated by the braking train to the AC power network, to achieve the goal of comprehensive utilization of energy, serving the purpose of energy saving. How to select the capacity of regenerative braking energy feedback device is an important subject of energy saving. Taking a domestic urban rail transit project as an example, this paper uses the methods of theoretical analysis, simulation and mathematical statistics to analyze the capacity selection for energy feedback device and the energy saving effect under different capacity scenarios.
