Re: Drivetrain Dynamic Model

Dear Jason, thank you so much for your replies. In the forum linked as https://wind.nrel.gov/forum/wind/viewtopic.php?t=525 you replied to another user that the equation of the drivetrain is T_Aero – J_Rotor*Alpha = DTTorSpr*(Azimuth-LSSGagPxs) + DTTorDmp*( RotSpeed- LSSGagVxs). I was expecting a te...

Drivetrain Dynamic Model

Greetings to the forum. For the purposes of my research work, I need to apply Kalman filter to estimate the rotor speed and rotor torque for the FAST 5MW NREL, v8. For this purpose, I use the Drivetrain model from Estimation of rotor effective wind speed: a comparison, MN Soltani et al . The schemat...

Re: estimator of effective/relative wind velocity

Hi to all, for the purposes of my research project I am trying to develop an effective wind speed estimator in Simulink for the 5 MW Fast Wind Turbine, in line with the work http://iopscience.iop.org/1742-6596/75/1/012082 appearing in the above post. My progress so far, is summarized as follows: - A...

Re: Yaw Control Using Bladed dll method

Hello Jason, Panagiotis,

Has either of you found a solution to this problem? We are running into the exact same problem with our .DLL controller.

Best regards,

Re: SOWFA Support

Dear SOWFA users, About the scheme blending question above, I have a problem when I try to run the ABLSolver (OpenFOAM 2.3.1 on Ubuntu 14.04). After creating the mesh, changing "buoyantPressure" for "fixedFluxPressure" in 0/p_rgh and setting initial field with setFieldsABL, I ge...
