Device and method for fatigue monitoring, system for managing a fatigue life distribution, method of operating a plurality of wind turbines

摘要

A device and a method for fatigue monitoring of a wind turbine generator structure of a wind turbine generator and a system for managing a fatigue distribution of an individual or of a plurality of wind turbine generators and a method of operating an individual or of a plurality of wind turbine generators is provided. A dynamic movement of the wind turbine generator structure is determined. Based on this input data, a dynamic movement of the wind turbine generator structure is simulated. A load in cross section of an observed component of a wind turbine generator structure is further determined and based on a time series for the load in the cross section of the observed component; an analysis is performed so as to assess a fatigue of the observed component.
