Abstract This paper discusses the simulation of lightning-induced voltages on a three-phase compact distribution line considering either a first order finite-difference time-domain solution of telegrapher's equations or a version of Marti's transmission line model extended to include the influence of external electromagnetic fields, named EMD model. The validity of both models is first demonstrated by means of comparisons with lightning-induced voltages measured in rocket-triggered lightning experiments. It is then shown that the EMD model can be used in the simulation of lightning-induced voltages on compact distribution lines provided special attention is given to the model fitting in the modal domain, regardless if complex or real poles are used. Results obtained with the vector fitting technique are seen to be more reliable than those obtained using Bode's asymptotic method, which must be used with caution in the modeling of compact distribution lines. The obtained results are relevant because compact distribution lines contain both bare and covered conductors, which is likely to pose difficulties to the simulation of transients with transmission line models based on modal-domain theory.

考虑不同线路模型的三相紧凑型配电线路雷电感应电压分析

摘要 本文讨论了在考虑电报方程的一阶有限差分时域解或扩展到包括外部电磁影响的 Marti 传输线模型版本的三相紧凑配电线上雷电感应电压的仿真。字段，命名为 EMD 模型。两种模型的有效性首先通过与火箭触发闪电实验中测量的闪电感应电压的比较来证明。然后表明 EMD 模型可用于模拟紧凑配电线路上的雷电感应电压，只要特别注意模态域中的模型拟合，无论是使用复极还是实极。使用矢量拟合技术获得的结果被认为比使用 Bode 渐近方法获得的结果更可靠，在紧凑配电线建模中必须谨慎使用。获得的结果是相关的，因为紧凑的配电线路包含裸导体和覆盖导体，这可能会给基于模态域理论的传输线模型的瞬态模拟带来困难。
