Re: DTU 10-MW Reference Wind Turbine

Dear Lixian, I'm glad that the controller is finally working at your side. Regarding the issues observed, I guess that a developer of the ROSCO controller would be the most suitable person to explain the specific behavior that you are observing. Note that there is a GitHub repository for the ROSCO c...

Re: DTU 10-MW Reference Wind Turbine

Dear Lixian, I have been using the IEA-10.0-198-RWT (based on the offshore DTU 10-MW wind turbine design) within the OC6 project. At the beginning I was also having problems with the blades pitch. The IEA-10.0-198-RWT uses the ROSCO controller. You can find a 64-bit version of this controller alread...

Re: DriveTrain Natural Frequency Calculation

Dear Jason, Thanks for your quick response. Nice to know that you have seen this behavior in field. I was not able to determine it in real wind turbines. I understand that it was due to the control algorithm used in that wind turbines. According to you I understand that DFIG and Permanent Magnet Gen...

Re: DriveTrain Natural Frequency Calculation

Dear Jason, Very good topic! I understand that free-free drivetrain condition gives quite similar results to fixed-free condition considering as "fixed" the hub side. On the other hand, free-fixed condition (considering as "fixed" the generator side) gives you a very low frequenc...
