Wind turbine generator large component damage analysis system based on data fusion

The invention relates to a wind turbine generator large component damage analysis system based on data fusion. The system comprises a station environment analysis system and a wind turbine generator fault information system. The station environment analysis system comprises a meteorological data analysis module, a terrain analysis module, a fluid simulation module and a wind measurement data analysis module; the wind turbine generator fault information system is used for obtaining electrical system fault information, mechanical system fault information, control system fault information and external influence information, analyzing abnormal performance of a fault unit and other units based on fault information prompts through unit operation data variables, and comprehensively judging the cause of damage of the large component in combination with weather, terrain, fluid, wind parameters, loads and the abnormal performance of the units. According to the system, a multi-data-source multi-angle fusion analysis tec
