How Wind Farms Use Measurements to Reduce Wake Loss
How Wind Farms Use Measurements to Reduce Wake Loss
A turbine changes the flow of air for machines downstream of it, and that interaction shifts with the wind.
Behind a rotor, air usually moves more slowly and becomes more turbulent. The size and direction of this wake depend on the weather and the layout of the farm.
Some control strategies make a small adjustment to an upstream turbine so the combined output improves. Such changes also affect loads, which have to be measured alongside energy.
Evaluate the farm as a group across different wind directions. Results from one sector or a short trial cannot describe the interaction across an entire year.
