摘要: 选择传输线模型作为雷电通道的回击模型,采用时域有限差分法首先计算了雷电回击通道附近的感应电磁场,接着运用Agrawal模型考虑雷电感应电磁场与架空电力线的耦合效应,分别计算架空电力线上不同点的感应过电压值,详细分析了雷电感应电压在单根架空线上的分布规律.

Abstract: The horizontal and vertical electric fields due to nearby lightning are calculated adopting the transmission line model. And lightning-induced voltages on an overhead line are evaluated by using the coupling model proposed by Agrawal et al. Finite difference time domain method is adopted in calculation of both fields and lightning-induced voltages. The distribution rule of lightning-induced voltage on an overhead line is obtained.

Key words: lightning electromagnetic pulse, finite difference time domain (FDTD), overhead line
