Summary
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. This paper details the construction of

Application analysis demonstrates that the system accurately and effectively performs qualitative analysis of lightning-induced faults in the distribution network. This capability facilitates precise rootcause diagnosis of line faults and guides maintenance personnel in formulating targeted preventive measures. Furthermore, the ground flash density maps generated by the system effectively direct operational units to implement differentiated lightning protection measures based on regional lightning activity characteristics.
