| Recommended semester: 7th - 9th semester |
| Evaluation: Oral presentation and approval of reports
|
| Examination: 13-scale |
| Preferred prerequisites: 41313">41313 41313">41313 plus basic programming skills as e.g Matlab, Fortran, Pascal or C |
| Aim: To give a thorough insight to the structural modeling of a wind turbine. To calculate the aeroelastic response of a wind turbine construction it is also necessary to include an understanding of the time varying loads stemming from turbulence in the incoming wind, wind shear from the atmospheric boundary layer and gravity and inertial forces. |
| Contents: Structural modeling of wind turbine using generalized coordinates, consistent mass and stiffness matrix, 3-D corrections to stationary airfoil data, implementation of dynamic stall models, implementation of instationary BEM model, modeling of atmospheric turbulence, wind shear, rain flow counting of time varying loads, numerical time integration of governing equations for motion of wind turbine, computer simulation of the time varying behavior of a wind turbine, modern control of wind turbine. |
| Remarks: A structural model of an entire wind turbine construction is programmed using a limited number of degrees of freedom. The structural model is coupled to an aerodynamic model for the loads. Further, the students are introduced to the commercial aeroelastic model FLEX. Different departments at DTU and the Department of Wind Energy, Risø will give the necessary key lectures. |
