Abstract:
A method and device for detecting equivalent load of wind turbine are provided. The method includes: detecting environment data of each wind turbine of multiple wind turbines in wind farm in each detection period; and in each detection period, detecting load of one or more calibration wind turbines in the multiple wind turbines, calculating equivalent load of the calibration wind turbines based on detected load, and determining equivalent load of each wind turbine based on detected environment data of each wind turbine with load estimation model, where load estimation model represents relation between environment data and equivalent load of wind turbine, and before load estimation model is applied in each detection period, parameter of load estimation model is calibrated based on the equivalent load calculated in current detection period and the equivalent load of the calibration wind turbines determined with load estimation model in previous detection period.
