输电线路绝缘击穿通常通过执行绝缘子链测试以及进行结合各种应力条件的网络建模和仿真研究来评估。本文研究了如何利用来自闪电探测网络和测量站的历史数据来捕捉相关天气条件，以提供对给定暴露和相关天气威胁的绝缘击穿风险的预测评估。拟议的分析是通过线路末端变电站记录的暂态数据的空间和时间相关性，以及通过同化从闪电探测网络和气象站获得的数据来实现的。所建议的建模和仿真工具被用来促进时间和空间相关性分析，从而预测风险。
The transmission line insulation breakdown is typically assessed by performing insulator chain tests, and by conducting network modeling and simulation studies incorporating various stress conditions. This paper investigates how historical data coming from the lightning detection network and measurement stations capturing associated weather conditions can be utilized to provide a predicted assessment of risk of insulation breakdown for a given exposure and associated weather threats. The proposed analysis is enabled by the space and time correlation of the transient data recorded in the substations at the end of the lines, as well as by the assimilation of data obtained from the lightning detection network and weather stations. The proposed modeling and simulation tools are utilized to facilitate the time and space correlation analysis that leads to predication of the risk.
