Abstract

Referring to IEC 61400-12-3, this study explores the factors affecting wind speed calibration relationships based on practical cases. The impacts of sensitive factors—including wind speed, wind shear, inflow angle, and turbulence—on wind speed calibration results are investigated respectively. Through calibration and quality assessment, it is found that the inflow angle exerts a greater influence on wind speed calibration than wind shear in the cases studied. The correlation between sensitive factors and the wind speed ratio affects calibration quality; when data bins with low correlation are excluded, the calibration quality improves to a certain extent. At the lower blade tip height, the airflow is more significantly affected by surface topography than at the hub height, resulting in poorer wind speed calibration quality at the lower blade tip that fails to meet the requirements of IEC 61400-12-3.
