Research on Energy Utilization Scheme of Regenerative Braking for Heavy Haul Railway

  • 摘要: 重载铁路运输作为铁路的重要发展方向之一,具有效率高、成本低且运能大的特点。近年来,我国重载铁路运能不断提高的同时,也使得能源消耗问题日益凸显。针对如何实现重载铁路的节能降耗,提出了一种基于混合储能的再生制动能量利用方案,通过利用蓄电池和超级电容器在性能上的互补性,实现混合储能系统对重载铁路再生制动能量的高效利用。结合神朔铁路的实测数据,对该条线路的负荷情况进行了分析,并针对混合储能系统设计了有效的能量管理策略,最后在实测数据的基础上对系统的经济性进行了评估。分析结果验证了提出能量管理策略的有效性,以及再生制动能量利用方案具有很好的经济性。

     

    Abstract: As one of the important development directions of railroad, heavy-duty railroad transportation has the characteristics of high efficiency, low cost and large capacity. In recent years, while China heavy-duty railroad capacity has been increasing, it also makes the problem of energy consumption increasingly prominent. A hybrid energy storage based regenerative braking energy utilization scheme is proposed to realize the efficient utilization of regenerative braking energy for heavy-duty railroads by using the complementary performance of storage battery and supercapacitor. The load conditions of the line are analyzed with the measured data of the Shenshuo railroad, and an effective energy management strategy is designed for the hybrid energy storage system, and finally the economics of the system is evaluated based on the measured data. The analysis results verify the effectiveness of the proposed energy management strategy and the good economics of the regenerative braking energy utilization scheme.
