铁路牵引站并网协调技术研究

Research on Grid Connected Coordination Technology of Railway Traction Station

近年来,我国电气化铁路快速发展,铁路牵引站数量不断增加。为了加强铁路牵引站的供电可靠性,减少牵引站接入对电力系统产生的不良影响,文章结合电气化铁路的负荷特性,分析其影响及解决措施。同时,梳理目前铁路牵引站存在的隐患及原因,研究电气化铁路供电的安全性和稳定性,最后针对牵引站的并网协调运行,对一、二次设备提出优化的建议,可为牵引站的接入和配置提供规划指导。

In recent years,electrified railway has been developed rapidly in China and the number of railway traction station has been increasing constantly.In order to strengthen the reliability of railway traction station and reduce the adverse effects made by power system access of traction station,this article combined the load characteristics of electrified railway,analyzed its impact and solutions.Furthermore,we study current hidden problems and their causes of the railway traction station,then researched the safety and stability of the electrified railway power supply.Finally,some suggestions on optimization of the primary equipment and secondary equipment are proposed for coordinated operation of the traction station,which can provide planning guidance for access and configuration of traction station.
