摘要
分析了牵引供电系统的构成,牵引变电所的AT供电方式,以及牵引供电系统中复杂的机车负荷特点。利用PSCAD软件对电力机车正常运行进行了仿真分析,验证了牵引供电系统的负荷特点,并对电网侧与牵引网侧发生单相接地故障进行了仿真分析与对比,探究了线路发生故障时对机车负荷的影响。
The composition of the traction power supply system,the AT power supply mode of the traction substation,and the complex locomotive load characteristics of the traction power supply system is analyzed in this paper.The load characteristics of the traction power supply system is verified by PSCAD software simulation analysis on the normal operation of the electric locomotive.The single-phase ground faults is simulated and compared on the grid side and the traction grid side,and effect of locomotive load is researched on the fault line.
