Abstract Meteorological radar technology has a very important application in power grid disaster prevention and mitigation. Radar technology is used to measure related disaster information, so that people can better take preventive measures and reduce the impact and loss of disasters on the power grid. Using the detection data of meteorological radar, the types of severe weather are automatically identified and divided, and objective short-term nowcasting and forecasting are automatically carried out. The generated early warning products are organically combined with the geographic information system to realize the accurate forecast of short-term severe weather, and accurately locate the power grid equipment through the spatial analysis service engine.
