Re: DTU 10-MW Reference Wind Turbine

Dear Dr. Nikhar

I'm sorry for the late response. The simulation problem has been solved after I used the latest version of 10MW WT downloaded in GitHub.
Thank you very much.
Also, many thanks to Dr. Roger and Jason!

Best regards

Re: DTU 10-MW Reference Wind Turbine

Dear Dr. Nikhar Thanks for your reply! Sorry about the vague, the X-axis is referred to the simulation time, not time step. The simulation time is 5000s. 1. Yes, "some numerical instabilities in the generator power'' means the drops in the generator power(1600 s) ,in the turbulent wind simulati...

Re: DTU 10-MW Reference Wind Turbine

Dear Dr. Roger Thanks for your reply! Now, It's working after I used the ROSCO controller according to your comments. Thanks again! I have another questions when using ROSCO controller. When I simulated the constant wind with wind speed (11.4 m/s) for monopile wind turbine, the simulation results lo...

Re: DTU 10-MW Reference Wind Turbine

Dear Dr.Jason Thanks for your quick response. I'm so sorry that I uploaded the wrong input files of servodyn. I think that I use the right path of dll file into servodyn file after I doubled checked the input files. I also found some simliar questiones in the fourm, and try to use "dtu_we_contr...

Re: DTU 10-MW Reference Wind Turbine

Dear Dr.Jason Thanks for reading my email. I'm using openfast v2.3 to simulate the IEA 10 MW reference wind turbine. And I used the DISCON_IEA_offshore.dll controller. However,I faced some problems when I simulated the rated wind speed condition(turbulent wind). The simulation can run but the blade ...

Re: The problem about Linearization result under parking situation

Dear Dr. Jason Jonkman Sorry to bother you! I'm using FAST to do the linearization analysis to calculate the eigenfrequency of each Dof, and the reference wind turbine is NREL 5-MW Onshore WT. This is the first time that I used FASTV8 to do the linearization analysis. During the analysis, I faced so...

Re: Simulating the parked turbine

Dear Dr.Jason

Thanks for you suggestions! Yes, maybe I should calculate the RAO first.

Re: Simulating the parked turbine

Dear Dr.Jason Thanks very much for your quick response. Regarding (1) : thank you, I have solved the problem, AeroDyn v15 can work now. Regarding (2): Yes, I am using elastoDyn output Thrust force. After I checked the related forum post, I understood that the RotThrust is not only including the aero...

Re: Simulating the parked turbine

Dear Dr. Jason Thanks for you reading my message. I'm using FAST V8 to simulate the parked condition of floating wind turbine in shallow water depth (50 m). And FAST stop running because of large platform motion. I have searched another people question here which is similar to my problem. In the loa...

FASTV8-HydroDyn-Wavemod4

Dear Dr.Jason Thanks for reading my message. I have some problems with the wavemod4. Here is my question: I'm trying to consider the modifed Jonswap spectrum in shallow water depth. So i need to multiply the Jonswap spectrum with the TMA factors to consider the shallow water effect. Fisrtly, I just ...
