Frontiers of Mechanical Engineering 2017, Volume 12, Issue 3, Pages 321-332 doi: 10.1007/s11465-017-0434-1

Abstract:

The magnitude and stability of power output are two key indices of wind turbines.First, wind speed models, particularly the wind shear model and the tower shadow model, are describedUnder steady wind conditions, power loss can be divided into wind farm loss and rotor loss.By contrast, rotor loss is strongly influenced by the wind turbine control strategies and wind speed.works, the rotor loss increases as the wind speed intensifies.
