Abstract:yphoon is a common disastrous weather in the middle east and southeast coastal areas of China. Strong winds,precipitation and secondary disasters associated with typhoons can seriously threaten the safe operation of power grid equipment.Moreover, the accuracy of typhoon prediction in traditional meteorological departments is limited, which is not of strong guiding significance for power grid to formulate typhoon prevention countermeasures. The main impact of typhoons on power grid equipment in coastal areas in recent years is analyzed, and the typhoon monitoring and early warning mechanism based on State Grid typhoon monitoring and early warning center is introduced, mainly including the overall structure of typhoon monitoring and early warning center, the functions of main station and substations, and the medium-term and short-term early warning release mechanism. The technologies and management measures related to typhoon resistance for power grid equipment, suchas dispatching emergency disposal, equipment performance improvement, hidden danger troubleshooting and treatment, and strengthening communication and linkage, are proposed. It is hoped that the discussion on the hazard characteristics, monitoring and prediction technologies and countermeasures for power grid suffering from typhoon will provide useful experiences for the typhoon prevention and wind resistance work of power grid.
