    摘要:

    根据雷电先导理论,分析配电线路走廊杆塔地形地貌对线路雷击风险的影响。首先,采用线路杆塔高程、地面倾角、土壤电阻率等特征量来表征塔位地形地貌,并建立特征量的量化赋值规则。随后,构造 BP人工神经网络分类器对山区配电线路杆塔地形地貌进行分类,所提分类可以满足配电线路杆塔雷击风险识别的实用要求,案例应用结果与实际情况相符。该文所提方法可为山区配电线路的差异化防雷提供新的思路。

    Abstract:

    According to the theory of lightning leader, the influence of tower topography on the lightning risk of distribution lineis analyzed in this paper. Firstly, the tower elevation, ground inclination, soil resistivity and other parameters are applied to characterize the tower topography, and then the quantitative value assignment rules of provided parameters are established. Secondly, the BP artificial neural network classifier is constructed to classify the topography of distribution line towers in mountainous areas, which can meet the practical requirements of lightning risk identification of distribution line towers. The case application results are consistent with the actual situation. The proposed method provides a new idea for differential lightning protection of distribution lines in mountainous areas.
