  • How turbulence can impact power performance Wind

     · The turbulence of the inflow to a turbine will impact the loads on the turbine and ultimately its life span. Certain scales of turbulence have very large impacts on loads. Even if the first row of turbines on a wind farm experiences smooth or non-turbulent flow turbines themselves generate turbulence in their wakes and the enhanced turbulence in turbine wakes increases the loads on downwind turbines.
