Kind Code:
A8
Abstract:
The present invention relates to a method of providing an estimate of remaining lifetime of a component in a wind turbine. The method may comprise providing a model for the component, obtaining a sensor signal from a sensor registering information regarding the component and registering the sensor signal for a first period of time, and determining an estimate of remaining life-time of a component based on the model and the sensor signal. The present invention further relates to a system for providing an estimate of remaining life-time of a component in a wind turbine. The system may comprise a memory unit adapted for storing a model for the component, a data receiver adapted for obtaining a sensor signal from a sensor registering information regarding the component and registering the sensor signal for a first period of time, and a processor adapted for providing an estimate of remaining life-time of a component based on the model and the sensor signals.
