Pitch Reference Tracking mode

[rhaghi]

Hi,

I have started working with ROSCO to tune a controller for a wind turbine based on the SCADA measurement. It has been an interesting journey, and I have learned a lot. Thank you very much for such a useful tool.

I activate PRC in DISCON.IN will dictate the RPM to the controller or the rotor per wind speed. I wonder if it is possible to have a similar setting for the pitch. I mean defining pitch set points for the controller, and the turbine should go through them. I guess that would provide the possibility of tuning the aerodynamics for the specific controller setting.

Let me know what you think.

Best,
Rad

Hi Rad,

For now, your best option would be to prescribe the minimum pitch vs wind speed like the peak shaving module does:

ROSCO/Examples/Test_Cases/IEA-15-240-RWT-UMaineSemi/DISCON-UMaineSemi.IN

Line 135 in 7deb583

!------- MINIMUM PITCH SATURATION -------------------------------------------

You could also define the pitch in open loop:

ROSCO/Examples/Test_Cases/IEA-15-240-RWT-UMaineSemi/DISCON-UMaineSemi.IN

Line 155 in 7deb583

!------- Open Loop Control -----------------------------------------------------

Right now, the open loop pitch versus time is the input, but it's not a huge jump to make the breakpoints wind speed. This has been on our to-do list for a while, but there are no active plans to implement it. Also, because it's not really how a wind turbine controller should work, but it has applications like you suggest.

If you're able to implement a change like this, we'd be happy to help integrate it.

Best, Dan
