摘要
介绍了电气化铁路电缆牵引供电方式原理,分析了电缆供电牵引网电流分配关系,并在MATLAB/SIMULINK仿真环境下,建立了电缆供电方式牵引网仿真模型,仿真分析了不同分段距离下牵引网短路阻抗、牵引臂长距离空载和负载条件下电压损失以及不同电缆截面下电流分配系数。
This paper describes the theory of electrified railway cable traction power supply, analyzes the current distribution of traction power supply cable network, establish the model of cable traction supply with software of MATLAB/SIMULINK, simulation the short-circuit impedance under different sub-traction and voltage loss of long-distance arm traction load and the current distribution factor with different cable cross-sectional area.
