ABSTRACT:
The invention relates to a method for reducing fatigue loads in the components of a wind turbine subjected to asymmetrical loading of its rotor, comprising the steps of: repeatedly collecting and storing load data of the rotor, determining a load distribution function for the rotor from said stored data, deriving a plurality of periodic functions from said load distribution function, determining actions for the wind turbine control means for reducing the fatigue load of the wind turbine components from said derived plurality of periodic functions, and implementing of said determined actions on the wind turbine control means. The invention also relates to a control system as well as a wind turbine and wind park.
