本文介绍了中国最大的闪电定位系统——广东闪电定位系统（GDLLS），该系统仅定位云地闪电中单个回击辐射的电磁场。 GDLLS 利用从 14 个组合磁方向和到达时间探测器传感器收集的信息，为电力行业提供实时和历史闪电数据。实时数据包括雷击时间、雷击位置和极性以及峰值电流的估计。本文讨论了 GDLLS 的性能，包括检测效率和定位精度。还讨论了 GDLLS 收集的闪电数据对于广东省电力公司的潜在应用。
This paper describes the largest lightning location system in China-Guang Dong lightning location system (GDLLS), which only locates the electromagnetic fields radiated by individual return strokes in cloud-to-ground flashes. Using information gathered from 14 combined magnetic direction and time-of-arrival finder sensors, the GDLLS provides both real-time and historical lightning data to the electric utility industry. The real-time data include the time of lightning strokes, their location and polarity and an estimate of the peak current. In this paper, the performance of the GDLLS is addressed, including detection efficiency and location accuracy. The potential applications of lightning data collected by the GDLLS are discussed also for electric power utilities in the Guang Dong province.
