Array models are muc h more sophisticated than he could even understand. The
simplest models use Fourier tranforms for the boundary layer effects on the
lumpy terrai n, and, for the wake development, turbulence levels computed
from interaction of atmospheric stability, ground roughness, tur bine sca le,
energy ex traction and wind speed gradien ts . A nd it's still not complete,
but tests on my ancient model in Swed en on a real 200 kW unit spinning in the
Baltic breeze were not too bad
Why not put in all the effort? There's lotsa $ involved. A nd dont' even
think of relo c ating a 1/2 mill $, 500 kW unit, the transfer would eat up 10
years profits!
It's a mistake to assume folks know less than you!
