摘　　要：针对三相交流牵引供电系统进行牵引网阻抗计算,该三相交流牵引供电系统采用一种新型的受电犁供电方式,其中使用的供电轨为不规则导体,采用有限元仿真软件ANSYS对供电轨阻抗进行仿真,得到其阻抗及等效半径,进而采用多导体回路法得到了三相交流牵引供电系统的牵引网阻抗,为新型牵引供电系统的系统阻抗求解问题提供了解决思路,对牵引供电系统建模及供电能力计算具有重要意义。The traction network impedance is calculated for the three-phase AC traction power supply system.In the system,the part that supplies power to the locomotive is not the contact line or the third rail used in the past,but a new type of power plow,in which the power supply rail is an irregular conductor.The finite element simulation software ANSYS is used to simulate the impedance of the power supply rail,and its impedance and equivalent radius are obtained.The results show that the traction network impedance of the three-phase AC traction power supply system is obtained by using the multi-conductor loop method,which provides a solution idea for solving the system impedance problem of the new traction power supply system,and it is of great significance to the modeling of the traction power supply system and the calculation of power supply capacity.
