Abstract: Methods of operating a wind turbine having one or more sensors for determining loads in selected wind turbine components, the methods comprising determining loads in the selected wind turbine components during a measuring period under a first wind condition, calculating a real power spectral density of one or more selected loads for each of the selected wind turbine components during the measuring period, obtaining a reference power spectral density for the selected loads for each of the selected wind turbine components under a wind condition that is comparable to the first wind condition, determining accumulated fatigue damage in time equivalent loads for each of the selected wind turbine components, verifying for each of the selected wind turbine components whether the accumulated fatigue damage in time equivalent loads is within acceptable limits, and performing one or more operational changes in case of negative result. Wind turbines suitable for these methods are also disclosed.
