Application of Lightning Monitoring System in Beijing Distribution Network

Beijing's power grid operates at a high-priority level for political power supply assurance, where lightning-caused trip-out faults significantly impact the security and stability of both transmission and distribution networks. While lightning online monitoring for overhead transmission lines is well-established, corresponding monitoring solutions are lacking for distribution-level overhead lines. To enable rapid diagnosis of line trip causes, expedited fault location, and swift power restoration, Beijing Power Grid has implemented a next-generation lightning monitoring system in its distribution network.
