Modern methods for investigating the stability of a pitching floating platform wind turbine
The QBlade implementation of the lifting-line free vortex wake (LLFVW) method was tested in conditions analogous to floating platform motion. Comparisons against two independent test cases using a variety of simulation methods show good agreement in thrust forces, rotor power, blade forces and ro...

| description | The QBlade implementation of the lifting-line free vortex wake (LLFVW) method
was tested in conditions analogous to floating platform motion. Comparisons
against two independent test cases using a variety of simulation methods
show good agreement in thrust forces, rotor power, blade forces and rotor
plane induction. Along with the many verifications already undertaken in
the literature, it seems that the code performs solidly even in these challenging
cases. Further to this, the key steps are presented from a new formulation of
the instantaneous aerodynamic thrust damping of a wind turbine rotor. A test
case with harmonic platform motion and collective blade pitch is used to
demonstrate how combining such tools can lead to a better understanding of
aeroelastic stability. A second case demonstrates a non-harmonic blade pitch
manoeuvre showing the versatility of the instantaneous damping method. |
