摘要
The present disclosure provides a method and system for calculating aerodynamic force of a wind turbine airfoil under different turbulence intensities. The method of the present disclosure includes: calculating a lift coefficient and a drag coefficient according to measured wind pressure, performing function fitting to obtain a fitted lift coefficient model and a fitted drag coefficient model at the different turbulence intensities, and selecting a corresponding fitted lift coefficient model and drag coefficient model according to a turbulence intensity on a wind turbine to be measured, to directly calculate a lift coefficient and a drag coefficient for the aerodynamic force of the airfoil.
