| Abstract: |
| The large scale wind turbines suffer more serious unsteady characters in complicated conditions,which brings about the aerodynamic and wake prediction becoming more complex.For steady yaw,dynamic yaw,wind shear and stochastic wind field,the free vortex method is used to calculate aerodynamic,and the dynamic stall model and the three dimensional stall delay model are taken into account.At the same time,the complicated conditions are added to the calculative code.Moreover,the data results of complicated conditions are compared with the numerical calculation of complicated conditions.Finally,the characteristics of aerodynamic performance,loads and tip vortex lines are found,and the overshoot and lag time of wind turbine loads are calculated.It is significant for pushing on the application of free vortex method on the mass loads calculations of the wind turbine,and improving the loads calculations accuracy and design quality of large scale wind turbines. |
