Data Analysis of Lightning Activity in High-Precision Lightning Monitoring System of Yunnan Distribution Network

Yunnan is located on the plateau with complex topography and geomorphology, and the lightning activity is high in the whole region, especially in Lijiang area. The existing wide - area lightning monitoring system cannot meet the application requirements of the distribution network for guiding the rapid query of line lightning strike faults and accident analysis. Therefore, a pilot project of a high - precision lightning monitoring system for the distribution network was carried out in Lijiang. This paper systematically analyzes and verifies the operation status, performance indicators and application functions of the high - precision lightning detection stations and the high - precision lightning monitoring system for the distribution network. The analysis shows that the high precision lightning monitoring system for the distribution network plays a huge role in identifying the causes of distribution network line faults, and can provide accurate and timely objective data support for lightning strike faults.
