METHOD TO REDUCE LOAD FATIGUE ON THE COMPONENTS OF A WIND TURBINE SUBMITTED TO ASYMMETRIC LOAD EFFORT OF YOUR ROTOR, CONTROL SYSTEM TO REDUCE FATIGUE BY EFFECTS OF LOADS ON A WATERPROOF WATERPROOF TURBINE COMPONENTS ITS ROTOR, WIND TURBINE, AND WIND CAPTURE AREA. The invention relates to a method to reduce fatigue due to the effect of loads on the components of a wind turbine subjected to asymmetric load stress on its rotor, which comprises the steps of: repeatedly collecting and storing the rotor load data, determining a function load distribution for the rotor from said stored data, derive a plurality of periodic functions from the load distribution function, determine actions for wind turbine control devices to reduce fatigue due to the effect of loads on components of a wind turbine based on said derivative plurality of periodic functions, and implementation of the said actions determined on the control devices of the wind turbine. The invention is also related to a control system as well as a wind turbine and a wind catchment area.
