WIND FLOW DEFORMATION INSIDE THE WIND FARM

The boundary-layer meso-gamma-model was used for calculating wind and turbulence characteristics inside the wind farm. The study demonstrate s the ability of the model to describe wind and turbulence fields in m ore detail than climatological analysis only. Velocity deficit at the hubheight of the wind turbine and standard deviation components inside the wind farm were calculated for various environmental situations wh ich are constructed as combinations of the large scale input parameter s of the model with surface and landscape characteristics. The load ef fects on the wind turbine were parameterized, and the calculated wind profiles inside the wind farm were compared with measurements. (C) 199 8 Elsevier Science Ltd. All rights reserved.
