Hi Rogier, thanks for your answer.
In fact, I have two time series, each one corresponding to a different measurement height (60 m and 100 m) in the same met mast, that is to say, I have two anemometers. So, in order to get a comparison between the GWC associated to each one of those anemometers, I used WAsP to calculate the AEP for the same wind farm twice, with the GWC generated. The analysis showed that there are remarkable differences whenever I change the GWC, even if they correspond to the same met mast, but at different heights.
My question is: is that difference due to any vertical extrapolation model limitation?
If it's not clear yet, please let me know. Thank you once again! -
Hi,
This may not be a very reasonable question, but I have a doubt concerning the difference between the generalised wind climate calculated from two hub heights with the same time series. I did it in my project for measured data at 60 m and 100 m height for a wind turbine with a hub height of 70 m, and I was expecting them to provide the same GWC, which did not occured. That led the wind farm capacity factor of each one to have a difference of almost 4%.
I would like to know if there is any obvious explanation for this, and if there is anything I can do to compensate for that discrepancy when calculating my wind farm AEP.
Thanks! -
Thank you for your answer, Andreas.

Hi,
I've inserted an obstacle group while setting the met. mast for my analysis, and now I want to generate a resource grid. Do I have to reassociate the same obstacle group to the new resource grid or, if I just let things as they are, WAsP will automatically associate the original obstacle group to the resource grid?
Thanks.
