Method and a system for controlling operation of a wind turbine
First Claim
1. A method for controlling the operation of a wind turbine, the method comprising:
- determining, with a failure mode analyzer of a Condition Based Operation (CBO) unit, at least one failure mode relating to at least one component of the wind turbine;
estimating, with a lifetime calculator of the CBO unit, a remaining lifetime of the component under current operating conditions;
determining, with a control unit of the CBO unit and based at least in part on the estimated remaining lifetime of the component under current operating conditions, a plurality of control schemes to control the operation of the wind turbine in order to adjust the remaining lifetime of the component to a desired remaining lifetime that allows the component to function until a selected future date;
determining, with a cost evaluator of the CBO unit, a power production yield for each of the determined control schemes; and
selecting one of the determined control schemes for controlling the operation of the wind turbine that maximizes the power production yield.

Abstract
A method and a system for controlling operation of a wind turbine are provided. The method includes determining at least one failure mode relating to one or more components of the wind turbine, estimating a remaining lifetime of the component under current operating conditions, determining one or more control schemes to control the operation of the wind turbine in order to adjust the remaining lifetime of the component to a desired remaining lifetime of the component, determining a power production yield for the determined one or more control schemes and selecting a determined control scheme for controlling the operation of the wind turbine that maximizes the power production yield.
