| 摘 要： | 城市轨道交通需要频繁的启动和制动,若对其制动时产生的能母进行合理利用.可以达到节约能源的作用.针对基于超级电容储能的1.5 kV城市轨道交通供电系统应用场合,研究了一种采用输入侧串联、超级电容侧独立组合结构的模块化再生制动能量利用系统方案;提出了适用于该方案的三环控制策略,可以实现能量的双向自由流动、超级电容电压和最大充放电电流限制、串联模块的输入电压均衡等功能;最后通过实验验证了该系统的可行性.

| Abstract: | Starting and barking happen frequently in urban rail system.Making good use of the energy generated in barking can realize the energy conservation.On the occasion of 1.5 kV power supply in urban rail system based on ultra capacitor,a modularization scheme of regenerating energy utilization is researched ,which strings the input and lets the output indepen-dent,then a control strategy with three loops is put forward,which can realize the bidirectional free flowing of Dower,the voltage-limitation and the max charge and discharge current limitation of ultra capacitor,and the input voltage-sharing of modular in series.Finally,the feasibility is validated through experiments. |
