| 摘要: |
| 铁路运输作为重要的基础设施和能源消耗大户，面临着显著的减碳压力。针对列车组高密度、重载化运营趋势下，牵引供电系统能源单一、再生制动能量回收难等问题导致的安全运行风险及能源利用率低等技术瓶颈，对铁路沿线可再生资源禀赋进行了分析。系统阐述了电-氢能源接入牵引供电系统组成模块，探讨了跨相式、同相式、贯通式结构下电-氢能源接入方式。在此基础上，分析了系统运行优化策略在实时调控、能源优化调度、决策精度等方面的应用效果。并基于氢能在跨区域运输、长时间储存及低碳经济方面的特性，分析了电-氢能源接入牵引供电系统的大规模制氢能力及其在运行安全与应急方面的供电韧性。 |

| Abstract: |
| As a vital infrastructure and a major consumer of energy, railway transportation is facing significant pressure to reduce carbon emissions. In response to technical bottlenecks, such as safety operation risks and low energy utilization rates, caused by the only energy sources in the traction power supply system and the difficulties in recovering regenerative braking energy under trends of high-density and heavy-haul train operations, this paper analyzes the renewable resource endowments along railway lines. It systematically elucidates the component modules of electric-hydrogen energy integration into the traction power supply system and explores the access methods of electric-hydrogen energy under cross-phase, same-phase, and through-type configurations. On this basis, this paper analyzes the application effects of system operational optimization strategies in terms of real-time regulation, energy optimization scheduling, and decision accuracy in real-time scheduling. Furthermore, based on the characteristics of hydrogen energy in cross-regional transport, long-term storage, and a low-carbon economy, it analyzes the large-scale hydrogen production capabilities of electric- hydrogen energy integration in the traction power supply system and its resilience in operational safety and emergency power supply. |
