Windvector instruction for energy generation assessment??


LennoxConner Jul 31, 2020 05:58 AM

Hi,

Could you confirm which option (0-4 OutputOpt) in the Windvector function is most appropriate for assessing wind power for turbines?

Should a unit speed variable or the nearest measured wind speed be used with the wind direction measurement with this setting, or does it not matter?

I've read the manual several times, but am still unsure.

Thanks,

Options 3 and 4 were created for wind energy applications. "Unit vector mean wind direction (WVc(1)) and standard deviation of wind direction (WVc(2))".

What this means is that every sample of the wind direction has an associated magnitude of 1. So there is no weighting of direction by wind speed and any wind speed association in the instruction will be ignored. You have to record the wind speed as a separate output. 

Most power performance models expect data collected this way and then use the direction and speed at their associated heights in their modeling software.
