Abstract:With the intensification of climate change, the power grid system often faces meteorological disaster risks such as flood prevention, lightning protection, and snow prevention, which restrict its operational stability and safety. At present, China"s meteorological departments are unable to meet the actual needs of the power grid system to defend against various adverse weather conditions due to a lack of necessary technical support in issuing meteorological forecasts and warnings. To solve the problems of efficient integration and standardized management of data, relevant researchers are exploring methods of organically integrating power meteorological forecasting products with power systems, and studying ways to integrate meteorological data from different sources, which is crucial for maintaining industry development. Based on this, this article develops and designs an interactive fusion system for power and meteorological multi-source data from two dimensions: system design and key technologies. The aim is to comprehensively utilize multiple data sources to improve forecasting accuracy and provide guarantees for the safe operation of the power grid.
