摘要

输电线路反闪络分析对输电服务质量具有重要意义。塔台浪涌阻抗是预测和估计反闪络的关键参数。在本文中，我们引入了一个新的多区域土壤模型，在使用全局全波建模方法的同时考虑了土壤模型沿传输线的变化。这种新的能力侧重于整个系统的暂态行为，以评估沿传输线发生的反闪络。

Multi-Region Soil Model for Transmission Line Backflashover Analysis

Analysis of transmission lines backflashovers is of particular importance for the service quality. The tower surge impedance is a key parameter for the prediction and estimation of backflashovers. In this paper we introduce a new multi-region soil model to take into account soil model variations along a transmission line while using a global full-wave modelling approach. This new capability focuses on the transient behavior of the whole system to assess backflashover occurrences along the transmission line.
