According to the characteristic parameters of horizontal axis wind turbine, the vortex cylinder model of yaw actuating disc is established, and the circumferential induced flow factor is calculated by the theory of vorticity momentum under steady state yaw. Considering the Pitt-Peters model as the convergence condition, the wind turbine yaw angle parameters are taken into account to establish a calculation model for calculating the axial induced flow coefficient of a horizontal axis wind turbine. The simulation calculation is carried out in a VC environment using C ++ language and the aerodynamic design and Performance calculation of the key issues, and verified by an example of the feasibility of the simulation process.
