摘要
介绍了锂离子电池储能系统在轨道交通再生制动能量回馈利用中的应用。为了确定电池储能系统的容量和功率等级,建立了再生制动能量的计算模型。通过该模型可以对单辆车的再生制动能量进行仿真计算。在此基础上研究了车辆再生制动时直流牵引网络的能量传递模型,分析了其它车辆运行状况对再生制动能量利用率的影响。并且以广州地铁4号线为例进行仿真研究,验证了轨道交通再生制动能量仿真模型的正确性,为电池储能系统的应用奠定了基础。
Abstract The Lithiumion battery energy storage system developed to save the regenerative braking energy in rail transisis introduced. In order to determine the capacity and the power level of the battery energy storage system,a cal- culation model of the systemis established, through which the regenerative braking energy of single train is simulated. On this basis, the energy transfer model of DC traction grid is researched in the condition ofregenerative braking, and the impact of utilization efficiency of the regenerated ener- gy is analyzed in the operating condition of other vehicles. Finally, Guangzhou metro Line 4 is taken for asimulation, the result verifies the feasibility of these simulation models and lays a foundation for the application of battery energy storage system.
