Abstract

Lightning strikes are a leading cause of outages on overhead transmission lines, significantly compromising power system reliability. Consequently, monitoring lightning activity is critical to mitigate its impact on lines with high outage rates. This study presents an autonomous lightning strike counter system utilizing a split-core Rogowski coil for non-invasive current measurement on transmission towers. The system combines the Rogowski coil with an active integrator circuit to reconstruct the incident current waveform from the coil voltage signal. A microcontroller-based processing unit records strike occurrences and classifies them by amplitude using predefined thresholds. Laboratory tests were carried out to evaluate the performance of the Rogowski coil and integrator circuit, validating the system accuracy in detecting current pulses associated with lightning strikes. Underway field tests will assess the sensor's reliability during long-term autonomous operation on 345-kV transmission towers. The results demonstrate that the proposed system represents a practical and cost-effective solution for lightning monitoring in remote areas, contributing to enhanced data collection for engineering studies and improved reliability of electrical infrastructure.

摘要

雷击是架空输电线路停电的主要原因，严重影响电力系统的可靠性。因此，监测雷电活动对于减轻其对高停电率线路的影响至关重要。本研究提出了一种自主雷击计数系统，该系统利用分体式罗戈夫斯基线圈对输电塔进行非侵入式电流测量。该系统将罗戈夫斯基线圈与有源积分电路相结合，从线圈电压信号中重建入射电流波形。基于微控制器的处理单元记录雷击事件，并使用预定义阈值按幅度对其进行分类。进行了实验室测试以评估罗戈夫斯基线圈和积分电路的性能，验证了系统在检测与雷击相关的电流脉冲方面的准确性。正在进行的现场测试将评估该传感器在345 kV输电塔长期自主运行期间的可靠性。结果表明，所提出的系统是偏远地区雷电监测的一种实用且经济高效的解决方案，有助于加强工程研究的数据收集并提高电气基础设施的可靠性。
