在Agrawal传输线模型的基础上,以典型信号—电磁脉冲作为干扰源,详细分析了参数变化对传输线终端负载电压和电流响应的影响。仿真结果表明,负载、传输线间距、平面波入射角和平面波极化角等参数变化对负载端响应有不同的影响。在此基础上,又对双线传输线和单导体传输线受干扰特性进行了对比分析。仿真分析结果为实际系统中由于电缆耦合产生的干扰分析提供了理论依据,并具有一定的参考价值。
Based on the Agrawal transmission line model, the influence of the parameter variation on the load voltage and current response of the transmission line terminal is analyzed in detail with the typical signal-electromagnetic pulse as the interference source. The simulation results show that the load, transmission line spacing, plane wave incident angle and plane wave polarization angle have different effects on the load side response. On this basis, the interference characteristics of two-wire transmission line and single-conductor transmission line are compared and analyzed. The simulation analysis results provide the theoretical basis for the interference analysis of the actual system due to cable coupling, and have certain reference value.
