Experimental Research on Hierarchical Protection of Wide Area Protection Measurement and Control System for Intelligent Traction Power Supply System

智能牵引供电系统已全面应用于智能京张高铁中,其广域保护测控系统的继电保护配置除满足基本要求外,还具有层次化保护、自愈重构等智能化功能。本文结合京张高铁联调联试智能化短路故障模拟试验对其层次化保护功能进行研究,从就地保护、站域保护、广域保护多个功能层次,通过在供电臂内进行T-R、F-R、T-F三种类型及不同供电方式条件下的短路试验验证,分析保护动作和故障测距等,对智能牵引供电系统的进一步运用具有参考意义。

The intelligent traction power supply system has been fully applied to the intelligent Beijing Zhangjiakou high speed railway.In addition to meeting the basic requirements,the relay protection configuration of its wide area protection,measurement and control system also has intelligent functions such as hierarchical protection,self-healing and reconstruction.In connection to the intelligent short-circuit fault simulation test of joint commissioning and joint test of Beijing Zhangjiakou high speed railway,the paper studies its hierarchical protection function,and analyzes the protection action and fault location through the short-circuit test verification of three types of T-R,F-R and T-F and different power supply conditions in the feeding section from the functional levels of local protection,station area protection and wide area protection,and it is able to provide references for the further application of intelligent traction power supply system.
