Parked turbine simulation

Dear Kylee,

I agree with your settings, except:

  • There is no reason to disable the drivetrain-torsion (DrTrDOF) and nacelle-yaw (YawDOF) degrees of freedom when parked.
  • There is no reason to both apply the high-speed shaft brake (HSSBrMode=1) and to disable the generator DOF (GenDOF=False); when GenDOF is disabled, the torques applied cannot accelerate or decelerate the generator. If you want to model possible slip of the brake, I would enable GenDOF while applying the brake.

Regarding (3), it is not common to park the rotor of utility-scale wind turbine with a brake except during maintenance operations. Normally during high winds when the wind turbine is shut down, the rotor is left to idle (rather than parked with a brake applied) with the blades feathered.

Best regards,
