Numerical Solution and Simulation Analysis of High Altitude Nuclear Electromagnetic Pulse Effect on Long Cable

本文研究了高空核电磁脉冲的作用下线缆的耦合效应,采用了Agrawal模型传输线分析方法,对高空核电磁脉冲耦合效应下的感应电流和电压进行了解析求解,讨论了入射波电场位于入射波平面左侧和右侧这两种情况时负载端感应电流数值解析式的差异,并通过MATLAB软件仿真,分别分析了这两种情况下不同线缆负载、线缆长度、线缆高度对终端感应电流的影响。

In this paper,the coupling effect of cables under the action of high-altitude nuclear electromagnetic pulse is studied.The Agrawal model transmission line analysis method is used to analytically solve the induced current and voltage under the coupling effect of high-altitude nuclear electromagnetic pulse.The difference in the numerical analytical formula of the induced current at the load end when the incident wave electric field is located on the left and right sides of the incident wave plane is discussed.Through MATLAB software simulation,the effects of different cable load,cable length and cable height on terminal induced current are analyzed.
