Wind turbines and methods for controlling wind turbine loading

摘要

Wind turbines (10) and methods (100) for controlling wind turbine loading are provided. In one embodiment, a method (100) includes the steps of determining a current wind speed. The method (100) further includes determining (110) a tip speed ratio (112) and a pitch angle (114) that maximize a power coefficient (116) under at least one of the following conditions: a thrust value is less than or equal to a pre-established maximum thrust, a generator speed value is less than or equal to a pre-established maximum generator speed, or a generator torque is less than or equal to a pre-established maximum generator torque. The method (100) further includes calculating (130) a desired generator speed value based (136) on the current wind speed and a tip speed ratio. The method (100) further includes calculating (134) a desired generator power value based on the desired generator speed value.
