[0161] The following will combine Figure 1-Figure 3 The technical scheme of the present invention is described in further detail.
[0162] In step S1, the Thompsontau-quartile method is used to identify and clean the abnormal wind speed-power operation data of the wind turbine to obtain a normal wind speed-power data set.
[0163] Step S2, according to the wind speed-power normal data scatter diagram, the annual power generation of the computer group, the average value of the power standard deviation below the rated wind speed, the average value of the power standard deviation above the rated wind speed, and the maximum value of the power coefficient below the rated wind speed.
[0164] Taking a wind turbine with a rated power of 1500kw as an example, the following are the measured data and related parameters of the wind turbine.
