Beschreibung
Zusammenfassung:	The invention discloses a wind turbine generator load calculation method and device, and the method comprises the following steps: obtaining the turbulence intensity data of each site of a wind turbine generator at different wind speeds, and extracting the envelope turbulence intensity corresponding to different wind speeds; according to the envelope turbulence intensity of the preset wind speed interval, fitting the turbulence intensity data in the preset wind speed interval, and obtaining fitting turbulence intensity; and calculating a load value of the wind turbine generator according to the fitting turbulence intensity, and judging whether the load value is in a normal range by combining a design load of the wind turbine generator. The invention comprises acquiring turbulence intensity data of each machine site of a wind turbine generator at different wind speeds, extracting envelope turbulence intensity, carrying out data fitting and calculating a load value of the wind turbine generator, replacing a tra
