shutdown strategy by azimuth

[nicolas bentz]

Hi everybody
We are new on the Wasp forum...
After a quick check on the historic of topics, I don't found any information about how to shutdown half of WTG windfarm according to some specific azimuth
Have you any wasp solution about this point?
Thank you for your response
Best regards

Hi Nicolas,


I just made an answer on the support help desk to someone who might be a colleague of yours. Anyway, the question is fairly general, so I see no confidentially problem in repeating the answer here. It goes like this...


"If your goal is to see the AEP of a reduced windfarm layout containing only every second turbine of the turbines in your present project, then the easiest way is to split the turbine group into two groups. You can then temporarily drag the turbines you don't want to include in the calculation outside the WAsP project, to the root level of the workspace object hierarchy, and repeat the calculations for the reduced wind farm. When you want to see the AEP of all the turbines you drag the turbine group back into the project.


Maybe this is not exactly what you need. Wind-farm operators sometimes use a strategy where some turbines are shut-down for certain wind directions to avoid excessive wake loads from neighboring turbines. This strategy is often referred to as sector management. Unfortunately, it is not yet supported in WAsP. We do however have a Windfarm Assessment Tool (WAT) which can make this calculation in an approximate way. You can read about this at http://www.wasp.dk/Software/WAT. You need WAsP Engineering to generate input to WAT, as one of its main features is to do IEC site assessment (extreme winds, turbulence, shear and flow inclination angles)."


Best regards,
Morten

Thank you Morten for your answer
You are fine, the point is a shutdown strategy for wakes loads from neighboring turbines.
Gael is a colleague of mine.
We will check the method by dragging, and maybe by WASP Engineering/WAT
