Wind turbine generator health state real-time evaluation method based on wind power measured data

The invention discloses a wind power measured data-based wind turbine generator health state real-time evaluation method. The method comprises the following steps: analyzing operation data in a wind turbine generator SCADA system, intercepting a data set through a periodically updated sliding window, establishing a sample set, completing data cleaning and screening, and drawing an actual wind speed-wind power scatter diagram; dividing the wind speed interval at equal intervals, and calculating a wind power average value in each sub-wind speed interval; theoretical wind power corresponding to the wind speed at the midpoint of the subinterval is obtained; introducing a wind turbine generator health evaluation index H, and performing grading evaluation on the health condition of the wind turbine generator; the time window moves forwards every fixed time, the sample set is updated, and the health state evaluation index H is recalculated. Starting from the operation purpose of the wind turbine generator, the evalu
