摘要

传输线中雷电感应电压需要知道峰值电流、回冲速度、前持续时间、通道衰减和失真等参数。它们的变化对结果的影响是不可预测的，在计算过程中，只有一个变化就会导致很高的计算成本。这项工作提出了一种基于统计工具的方法，该方法提供了将传输线上感应的最大电压与前持续时间和回行程速度联系起来的分析公式。通过一个已验证的耦合代码验证了分析和公式的正确性。

Lightning Current Parameters Effects on the Induced Overvoltages in Transmission Lines

The lightning induced voltages in a transmission line need the knowledge of many parameters such as the peak current, the return stroke velocity, the front duration, the channel attenuation and distortion. Their variation affect the results in a non-predictable way and only one variation can cause a high computational cost in the computation procedure. This work presents a method, based on a statistical tool that provides an analytical formula linking the maximum voltage induced on a transmission line with the front duration and the return stroke speed. The analysis and the proposed formula is validated with the results provided by a verified coupling code.
