Re: TIMESR Simulation

Dear Jason,

Yes, the only change was the turbulent wind.

I am simulating the Levenmouth Wind Turbine (Samsung Heavy Industries S7.0-171) with the Basic DTU Wind Energy controller adequately tuned.

All the Best,
Jordi

TIMESR Simulation

Dear Jason, I have generated a full field wind file from SCADA wind data with TurbSim v2.00.00 and the TIMESR capability. I have used a previous FAST model that works fine for "normal" turbulent winds, i.e. with no user-defined time series, and when I run the TIMESR wind file into FAST, I ...

Re: TIMESR

Dear Jason, Thank you for your kindly support. I have managed to solve the problem by: 1) Switching off the Simple variable-speed control. 2) Reducing the time step. My blades are extremely flexible, I am not sure if this fact can lead to the numerical instability itself, but most importantly I am u...

Re: TIMESR

Dear Jason, Thank you for your directions. I have managed to create both *.bts and *.wnd files. My goal is to compare SCADA records with simulations, both FAST and Bladed. When I run the FAST model with the new *.bts file I get the next mesage: FAST_Solution:CalcOutputs_And_SolveForInputs:SolveOptio...

Re: Wind file: FAST vs Bladed

Dear Jason, Thank you for your comments. Yes, I have eliminated the shear in Bladed. No, the results are not merely time shifted. There are also small differences in maximum and minimum amplitudes. I am not sure about the position. Certainly, I can check the Z (RefHt), but how can I check X and Y in...

TIMESR

Hi there,

Could you kindly provide me with a sample input file for user-defined profiles (TurbSim-TIMESR)?

Kind Regards,

Wind file: FAST vs Bladed

Dear Bonnie, I am trying to set up a FAST model of the Levenmouth wind turbine, and compare the results with the commissioning results. I have produced a *.wnd and *.bts wind file with TurbSim64 to use it in Bladed and FAST respectively. After running the simulation I have realised that the signal p...

Re: turbine geometry

Dear Jason, Thank you very much for your prompt and useful answer. Giving distributed values for the 80m, and setting up TowerHt=107m gives me the next error message: FAST_InitializeAll:InitModuleMappings:ED_L_2_AD_L_T:MeshMapCreate:CreateMotionMap_L2_to_L2:CreateMapping_ProjectToLine2:Node 1 does n...

turbine geometry

Dear Bonnie/Jason, I have a question regarding how to define the geometry of the turbine. Please, have a look at the attached drawing. levenmouth.png TowerHt would be B? (B is 107m) TowerBsHt would be (C=9m)+18m= 27m? If so, should I provide the tower distributed properties from 0 to 107m? Or only f...

Meshing error?

Dear Dr.Jonkman, Thank you for your time and attention. I am developing a simulation for the 7MW Levenmouth turbine. I have received the turbine parameters and I have started to introduce them into the input files. My first goal is to simulate an onshore configuration. After building the main input ...
