| 中文摘要: |
| 在分析牵引网等效电路及其等值阻抗的基础上,利用MATLAB的电力系统工具箱建立牵引网短路时牵引供电系统的仿真模型,进行仿真,得出了故障时的电压、电流波形及其序分量、谐波,测量了牵引网短路阻抗随短路点位置变化的曲线,分析了其故障特征.对牵引供电系统的故障分析、继电保护整定具有指导意义. |
| 英文摘要: |
| This paper introduces the traction power supply system,and analyses its equivalent circuit and equivalent impedance.The short-circuit fault′s simulation model has been establighed using the MATLAB toolbox.The waves of voltage and current which occurred at the fault point were got.The impedance curve along with the distance of tractionnet’s breakpoint has been measured.The charocteristic at fault was analysed. |
