摘要
地铁作为一种运载量大、速度快的轨道交通工具,能够有效缓解城市交通拥堵及尾气排放污染等问题.然而,由于地铁站间距离短、机车制动频繁,造成能量损失大.针对该问题,研究将制动时所产生的再生能量直接回馈到交流电网.创新性地提出通过一套一体化系统实现地铁能量回馈与谐波治理两种工作模式的综合,不仅充分利用地铁制动能量,还兼顾谐波治理.在Matlab中验证了本系统的可行性.本研究对城市地铁供电安全与电能节约具有理论与工程双重意义.
As a means of fast rail transport vehicle with large carrying capabilities, subways can be used to address problems associated with congestion and exhaust emissions. There is, nonetheless, a huge loss of power due to short distances between subway stations and trains’ frequent brakes. To deal with such problems, this paper attempts to explore the ways of using regenerated energies generated by braking in AC power network. An innovative system is proposed for reusing such energies and harmonic control. This system is proved feasible by using Matlab. This research is of great theoretical and engineering significance to power safety and electric energy saving of urban subways.
