Dianci bileiqi输配电线路防雷的重点均在于降低杆塔的接地电阻，但配电线路杆塔往往因距离居民生活区较近而缺少一定的接地施工面积，使得常规的杆塔降阻措施的应用受到了一定限制，并存在接地电阻不能达标等问题。首先利用有限元仿真计算软件COMSOL Multiphysics建立了配电线路杆塔桩基自然接地仿真模型，计算分析土壤电阻率、杆塔埋深等因素对桩基冲击散流特性的影响规律；然后针对现有同塔多回配电线路所面临的耐雷性能不佳与接地降阻可供施工面积不足等问题，提出基于柔性接地模块的杆塔紧凑型接地降阻策略 ...

基于多头注意力机制的CNN-BiLSTM高海拔多因素输电线路可听噪声预测
Gaoya dianqi为了研究考虑高海拔多环境因素影响下输电线路可听噪声的预测问题，在海拔2 400 m高度点的500 kV同塔双回线路下，搭建了边相外20、30、35 m三处可听噪声观测站，同时利用气象站进行多环境因素指标的数据采集。文中提出了一种基于多头注意力机制（multi-head attention，MHA）的卷积神经网络（convolutional neural network，CNN）—双向长短期记忆网络（bi-directional long short term memory，BiLSTM ...
