Automatic Diagnosis Technology of Lightning Fault in Transmission Line

Lightning fault is the main fault of transmission line. Accurate and effective diagnosis of lightning fault can effectively improve the reliability level of transmission line. At present, the determination of lightning strike fault and the location of the lightning strike are determined by manually inquiring the lightning locating system after the lightning strike. In order to improve the real -time determination of lightning fault, the accuracy of lightning strike point positioning and to shorten the outage time due to the lightning strike fault, research on the automatic fault diagnosis technology of the lightning failure of transmission line. According to the lightning fault of the transmission line, the information such as the relevant information of the lightning location system, the GIS information, fault recorder data, the scheduling automation data and the multi-terminal fault location information are used to realize the accurate positioning of the tower and the automatic fault diagnosis function of the transmission line fault. The rapid detection and overhaul of lightning failure is of great significance to the safe and stable operation of power grid.
