Re: Simulation of an offshore Wind turbine 5MW based DFIG

Sorry for my multiples asking, but my thesis is based on this code AND I nedded to know these details
Tel me again if some structures of the code are based on finite element method, or what position of this method in this simulateur

Sincerely yours

Re: Simulation of an offshore Wind turbine 5MW based DFIG

A simple aking, when we said the first and second flap-wise mode, tel me if it means the bending and its derivative, or what

Re: Simulation of an offshore Wind turbine 5MW based DFIG

On which model is based FAST. I found it is based on the modularization , can we said that the components of the WT is modelled as bodies linked with DOFs?

Re: Simulation of an offshore Wind turbine 5MW based DFIG

Mr Jason Thank you for your reply I have found in litterature that the WT may be modelled from one to sex MASS model I have found that in FAST the drive train is two mass model (2DOFs) in addition 9 DOFs of the blades. If we take the sex mass model we found the blades are modelled by 3 inertia, hub ...

Re: Simulation of an offshore Wind turbine 5MW based DFIG

Thank you very much Mr Jason

I meant what represent the "flap-wise bending moment at the root of the blades". Normally the moment is always calculated according an point, tell me at which point is calculated this moment in the figure attached

Re: Simulation of an offshore Wind turbine 5MW based DFIG

Tell me if furling-Tail represent the blades rotations away from the direction of the wind, either horizontally or vertically. And tell me also what is the difference between them and the yaw roation I want also to know Mr jason if the flap-wise bending moment at the root of the pales is the moment ...

Re: Simulation of an offshore Wind turbine 5MW based DFIG

Dear Mr Jason I hope you are well Tell me please why are you called the NREL's 5MW WT as a benchmarking model As well as the torque and GSPI why are you called they as reference controllers As I know the word benchmarking must verify somes standard norms,which norms have benn verifyed by this model ...

Re: Simulation of an offshore Wind turbine 5MW based DFIG

Normally each Flap-wise DOF will give you 6 states which are the displacments and velocities of the corresponding DOF

Re: Simulation of an offshore Wind turbine 5MW based DFIG

Thank you for these explantations

Can we said that the DOGs of the foundation are: the displacements and rotations around the three axes of the repere located at the fondation

Re: Simulation of an offshore Wind turbine 5MW based DFIG

Dear Mr Jason can you please qives the explantations of these stuffs or confirm: 1) If Gendof is the vitesse or the dispalcment of the generateur 2) If flap-wise is the deplacment of the blade in the direction normal to the rotor plan 3) If fore-aft is the tower displacment in the plan normal to the...
