摘要:
城市轨道交通供电系统一般采用集中供电方式，每条线路设置多个主变电所作为供电电源，并互相支援，以满足供电可靠性。但各城市轨道交通线路经常受土建或主变电所建设进度影响，在开通试运营时存在因供电电源点不足需设置临时电源的问题；同时，随着线网进入网络化运行阶段，亦存在灵活调整线网供电方式的需要。根据城市轨道交通供电系统中压网络一般采用环网接线方式的特点，结合工程实例，分析了在换乘站设置线间联络环网的必要性及可行性，提出了不同建设时序线间联络环网实施建议，分析了基于线网电力调度平台的线间联络环网应用前景。在换乘站设置线间联络环网，为保证在建及后续建设线路按期开通提供了一种临时电源或备用电源的设置思路，也为线网网络化运行提供了多种供电架构及供电方式选择。
Abstracts:
Power supply systems for urban rail transit generally adopt centralized power supply mode, each line deploys multiple main substations as its power source and these main substations assist each other to guarantee the power supply reliability. However, being constantly influenced by construction process of civil engineering or main substations, urban rail transit lines sometimes have to build temporary power sources due to the insufficient power sources for trial operation. Meanwhile, as line networks stepping into the stage of networking operation, adjusting the power supply modes in a flexible way is needed. Considering the feature that medium-voltage network in urban rail transit power supply system usually adopts ring network connection mode, combined with practical engineering cases, the necessity and feasibility of deploying interconnection ring network among lines at the interchange stations are analyzed.Suggestions for implementing interconnection ring network among lines in different construction time sequences are proposed.The application prospect of interconnection ring network based on line network power dispatching platform is also analyzed.To ensure lines to be launched on time either under construction or in future plans, setting interconnection ring network at interchange station provides an idea of establishing temporary power source or back-up power source, meanwhile, providing a variety of power supply architectures and power supply mode options for the networking operation of the line network.
