超级电容在城市轨道车辆中的节能应用

Application of Energy-saving On-board Supercapacitor in Urban Railway Vehicle

根据城市轨道车辆频繁启动和制动的特点,提出一种新的基于车载电阻制动能量控制的方法,对电阻制动能量进行回收并合理利用,减小列车制动时在制动电阻上的能量消耗,采用超级电容作为储能元件以回收电阻制动能量。基于对上海地铁2号线试验测试能量的详细分析,以及结合超级电容的各种特性,确定回收电阻制动能量时超级电容的容量。

Control method of resistance braking energy was proposed according to the continual start-up and braking of the urban railway vehicle, and the resistance braking energy was made reasonable use of and the energy consumption was reduced in the on-board resistance. The supercapacitor was used in this method as the energy storage equipment to retrieve and reuse the braking energy reasonably. The volume of the supercapacitor needed for the braking energy was ascertained based on the analysis of the tested energy of Shanghai Sub- way Line 2 and important properties of the supercapacitor.
