| 摘 要： | 研究了车载超级电容储能装置在改善电网电压方面的应用.在城市轨道交通中,列车加速时,由于线路阻抗的存在导致直流电网电压下降;制动时,再生能量反馈回直流电网,使电压抬升,为了避免再生失效,通常由电阻消耗再生能量.提出应用直流储能装置解决以上问题,提出超级电容储能装置的组成及设计方法,制定了相应的控制策略,最后以广州地铁4号线参数为例对实际车辆进行了仿真,验证了超级电容储能装置在改善电网电压方面的重要作用.

| Abstract: | The application of electric double layer capacitor(EDLC) on board in improving pantograph voltage fluctuation was described.In the urban railway traffic,pantograph voltage,in accelerating,will drop due to absorb current from electric network,and in braking,the voltage will rise and the regenerated energy is usually dissipated in a braking resistor.That wastes lots of energy,also lead to electric network voltage fluctuation.EDLC was applied to resolve the problems above,constitution of storage installation w... |
