Gaoya dianqi随着无人机以及各种控制技术的发展，无人机巡检技术被广泛地应用于电网。目前，无人机在电磁场环境下的避障还存在一些缺陷。为了探讨无人机在巡检时，现场运行输电线路对无人机表面电场的影响，文中通过SolidWorks建立了铁塔、导线、大疆M300RTK无人机、电场传感器等设备的模型，导入有限元仿真计算软件Ansoft Maxwell中开展了整体的电场计算。通过改变电压角度获得了一个最合适电压值作为静电场仿真的运行输电线路设置电压，仿真研究了不同距离条件下，无人机、机翼、传感器位置等对无人机表面电场的影响 ...

Gaoya dianqi, 2019 高压直流输电的快速发展使得平波电抗器成为换流站电磁污染的主要来源。为降低平波电抗器周围的空间磁场,对胶东±660 kV换流变电站满负荷运行条件下极母线平波电抗器的空间磁感应强度进行测量得到平波电抗器实际的磁感应强度分布,通过数据处理消除了地磁场对测试数据的明显影响,建立了平波电抗器在静磁场下的磁场分布模型并结合测量数据验证了计算模型的准确性。最终提出了几种磁场屏蔽方案,通过比较不同材料、尺寸及位置下屏蔽体的屏蔽效果的比较,得出了最优的屏蔽体架设方案。
