海上高压直流(HVDC)风电场为未来不断增长的能源需求提供了一个很有前途的解决方案。变电站资产的状态监测对于电网的可靠和弹性运行是必不可少的。陆上变电站和电网资产的现有状况监测技术包括训练有素的人员定期和按计划实地视察变电站地点。然而，这种例行检查对于近海油田来说并不是一个划算的解决方案。在访问网络资产变得困难的情况下，机器人和自主的状况监控提供了解决方案。这种机器人/自主解决方案需要与周围变电站环境互动，而不会增加不同带电部件之间的电气故障和闪络风险。在本文的A部分，从以下两个方面分析了高压静电场对无人机检测的影响：1)交流电晕辐射对无人机的干扰；2)空气击穿清除特性。仿真和实验结果都表明，电晕干扰对无人机自动驾驶仪和执行机构都有影响，这就需要一种屏蔽缓解方案。此外，实验结果还表明，引入屏蔽溶液对增加阀厅塔之间的闪络风险的效果有限。
Offshore high voltage DC (HVDC) wind farms offer a promising solution to growing energy demands in the future. Condition monitoring of substation assets is essential for reliable and resilient operation of electrical networks. Existing condition monitoring techniques for onshore substation and electrical network assets include regular and scheduled on-site visits by trained personnel to substation sites. However, such routine inspection is not a cost-effective solution for offshore sites. In cases where the accessibility to network assets becomes difficult, robotic and autonomous condition monitoring provides a solution. Such a robotic/autonomous solution would need to interact with the surrounding substation environment, without increasing the risk of electrical breakdown and flashovers between different energized components. In Part A of this paper, the effect of high electrostatic fields on an inspection unmanned aerial vehicle (UAV) is analyzed, with respect to: 1) AC corona emissions interference on the UAV, and 2) Air breakdown clearance characteristics. Both simulations and experiment results presented in the paper show the impact of corona emissions interference to both UAV autopilot and actuation sections, which requires a shielding mitigation solution. Also, experiment results show the limited effect of introducing a shielding solution on increasing the flashover risk between valve hall towers.
