Abstract

This paper investigates the use of ultracapacitors as an energy storage system for metropolitan railway systems. The basic concept is to take advantage of the energy generated during the braking process of trains, which is otherwise wasted and transformed into heat. A power system simulation was created as a tool to analyze the behavior of a stationary ultracapacitor bank connected to the Metro system. Ultracapacitor modules were dimensioned adequately, power electronic elements were adjusted and further a control system was established. Amongst others the simulation demonstrates the impact of varying the distance between ultracapacitors and traction power substation. Furthermore the dependency of the ultracapacitor's technical specifications on charging and discharging behavior is shown. The simulation allows a large number of parameters to be modified through the easy-to-handle user interface. A scientific method is provided to analyze ultracapacitor assisted regenerative braking of metropolitan railway systems. As an example the Metro of Medellín in Colombia is applied and rounded out by an estimation of economic viability.

都市铁路系统中超级电容辅助再生制动

本文研究了超级电容器作为城市轨道交通系统的储能系统。其基本概念是利用火车制动过程中产生的能量，否则这些能量会被浪费并转化为热量。建立了一个电力系统仿真系统，作为分析与地铁系统连接的固定式超级电容器组行为的工具。确定了超级电容模块的尺寸，对电力电子元件进行了调整，并建立了控制系统。其中，仿真显示了改变超级电容器与牵引变电所之间距离的影响。此外，还说明了超级电容器的技术指标与充放电性能的关系。该仿真允许通过易于操作的用户界面修改大量参数。为分析城市轨道交通系统的超级电容辅助再生制动提供了一种科学的方法。作为一个例子，哥伦比亚的Medellín地铁通过对经济可行性的估计加以应用和完善。
