市域快轨供电制式及车辆选型研究

Research on power supply system and vehicle selection for urban express railway

市域快轨是大城市市域范围内的客运轨道交通线路,对于构建综合立体交通网络有着至关重要的作用。在其规划建设过程中,供电制式及车辆选型研究是核心关键,需要全面权衡线网衔接方式、功能定位、资源共享、速度目标以及对工程建设和后期运营维护成本的影响等多方面因素。其中,对于实现互联互通和跨线运营的线路,需要在线路条件、技术标准等方面保持统一或兼容,以满足跨线运营的必要条件。而对于独立运营的线路,则需重点分析供电制式、车辆选型对工程建设及运营维护费用的影响,并据此做出合理选择,以提高项目的技术经济效益。文章基于上述理论对市域快轨供电制式及车辆选型进行相应研究,以期为后续市域快轨项目的规划建设工作提供参考和借鉴。

Urban express railway is a passenger rail transit line within the metropolitan area of a large city,which plays a crucial role in building a comprehensive three-dimensional rail transit network.The research on power supply system and vehicle selection is of utmost importance in the planning and construction of urban rapid rail transit projects,and it is necessary to comprehensively consider various factors such as network connection mode,functional positioning,resource sharing,speed target,and the impact on engineering construction and operation and maintenance costs.For interconnection and through operation lines,it is necessary to maintain consistency or compatibility in terms of line conditions,technical standards,etc.,and meet the conditions for through operation.For independently operated lines,it is necessary to focus on analyzing the impact of power supply systems and vehicle selection on engineering construction and operation and maintenance costs,make reasonable choices to improve the technical and economic benefits of the project.Based on the above theories,this article carries out corresponding research on the power supply system and vehicle selection of urban express railway,so as provide certain reference and a case to build on for the planning and construction of subsequent urban express railway projects.
