    摘要： Methods and systems for controlling operation of a wind turbine. The method may comprise determining an alarm level for at least one component of the wind turbine. In the case that an alarm level for at least one component exceeds a predefined level, the method comprises estimating an expected remaining lifetime for the component under the current operating conditions, and controlling operation of the wind turbine in order to adjust the expected remaining lifetime for the component to a desired expected remaining lifetime for said component. Thereby, the expected remaining lifetime for the component can be prolonged until the next scheduled service event. Downtime of the wind turbine is considerably reduced, and unscheduled service events are avoided to the greatest possible extent. Mean time between inspections (MTBI) is also extended.

    摘要： A method for controlling the operation of a wind turbine includes determining a first measure of a mechanical input of a component of the wind turbine, and concurrently, determining a second measure of a mechanical output of the component, determining an operating frequency response function of the component from an analysis of the relation between the first measure and the second measure, comparing the operating frequency response function with a predetermined operating frequency response function and determining a possible deviation between the two, and controlling the operation of the wind turbine so as to alter the mechanical input to the component in response to the deviation. A wind turbine that implements such a method is also disclosed.

    摘要： A method and a system for adjusting alarm level of a component in a wind turbine is provided. The method comprises defining an alarm level corresponding to an operational parameter of the component in the wind turbine, monitoring the operational parameter of the component, determining whether the operational parameter exceeds the alarm level, thereby triggering an alarm. In the case when the alarm is triggered, the method further comprises inspecting the component to determine whether the alarm level corresponds to a predetermined remaining useful lifetime of the component, and adjusting the alarm level based on the inspection of the component.
