摘要

热带地区的架空输电线路经常因雷击而中断供电。高闪电密度使得塔身发生屏蔽失效或反闪络的概率更高。因此，缓解是必要的。本文对66千伏防雷塔设计的改进方案进行了评价。提供的模型评估了极性、打击时间和雷电峰值电流对66 kV架空输电线路性能的影响，以及两种改善屏蔽保护的方案，即增加接地线和提升塔锥顶。

Modeling and Simulation to Improve 66 kV Overhead Transmission Lines Performance toward Lightning Strike

Outages due to lightning stroke frequently occur on the overhead transmission line operating under tropical conditions. The high lightning flash density makes a higher probability of having either shielding failure or back flashover at the tower. Therefore, mitigation is necessary. This paper evaluates options to improve the 66 kV tower design against a lightning strike. Provided models evaluate effect of polarity, strike time, and lightning peak currents on the performance of 66 kV overhead transmission lines also two scenarios of improving shielding protection, i.e., by additional ground wire and by elevating the cone top of the tower.
