Abstract
The invention provides a wind turbine, a control system for a wind turbine and a method for controlling a wind turbine where asymmetry in load on the rotor is compensated by individual pitching by comparing a load distribution over the rotor plane with a threshold value. To avoid unnecessary compensation, the threshold value is adjusted based on a loading of the wind turbine or based on climate conditions under which the turbine operates.
