Abstract: A method is provided of controlling a wind turbine that is operating according to a control signal causing the wind turbine to be over-rated above the wind turbine's rated power. The method comprises: obtaining one or more signals, or values of variables, that indicate the fatigue lifetime of one or more of the wind turbine's components from turbine sensors; applying a lifetime usage estimator algorithm to the signals or values to determine measures of the fatigue life consumed by each of the turbine components; calculating, for each of the turbine components, a rate of consumption of fatigue life based on the measures of the fatigue life consumed by each of the turbine components; and controlling the turbine to reduce the amount of power by which the wind turbine is over-rated based on the rate of consumption of fatigue life for at least one of the turbine components.

Abstract: Aspects described herein include a method of generating a control schedule for a wind turbine. The control schedule specifies a maximum power level that varies over time. The method comprises determining a value indicative of a current remaining fatigue lifetime of the wind turbine or of one or more components. The method further comprises applying an optimization function to perform an optimization to determine an optimized control schedule. The optimization comprises varying a plurality of parameters of an initial control schedule to produce a varied control schedule, estimating a future fatigue lifetime to be consumed by the wind turbine or the one or more components over the duration of the varied control schedule, and constraining the optimization according to one or more input constraints.

Abstract: Generating a control schedule for a wind turbine, the control schedule indicating how the turbine maximum power level varies over time. Generating the control schedule includes determining a value indicative of the current remaining fatigue lifetime of the turbine, or one or more turbine components, based on measured wind turbine site and/or operating data; applying an optimisation function that varies an initial control schedule to determine an optimised control schedule by varying the trade off between energy capture and fatigue life consumed by the turbine or the one or more turbine components until an optimised control schedule is determined.

Abstract: A method for controlling a wind turbine is provided. The wind turbine is a turbine of the type that is operated to perform a control function that controls the amount of power produced based upon measures of fatigue life consumption of one or more turbine components. The method comprises initialising the control function by: over-riding or bypassing (405) the control function for a predetermined period of time, such that power produced by the wind turbine is not altered based upon the determined measures of fatigue life consumption; during the predetermined period of time, operating (407) one or more fatigue lifetime usage estimation algorithms, to determine a measure of the fatigue life consumed by each of the one or more turbine components; and after the predetermined period of time has elapsed, activating (409) the control function and using, in the control function, at least one of the measures of fatigue life consumption determined during the predetermined period of time. A corresponding wind turbine controller and wind power plant controller are also provided.

Abstract: A method of controlling a wind turbine is provided. The method comprises determining a target fatigue life consumption for each of one or more components of the wind turbine; comparing the target fatigue life consumption with a measure of fatigue life consumption for each of the one or more turbine components; and controlling the turbine power output based upon the comparison. The target fatigue life consumption is determined by combining data indicative of a target rate of accumulation of fatigue damage over at least a portion of the operating life of the wind turbine and data indicative of an expected rate of accumulation of fatigue damage caused by seasonal variations in turbine operating conditions. A corresponding wind turbine controller and wind power plant controller is also provided.

Abstract: A wind turbine power plant comprises a plurality of wind turbines, each having a rated output and under the control of a power plant controller. The power plant also has a rated output which may be over-rated in response to one or more of electricity pricing data, power plant age and operator demand. The power plant controller can send over-rating demand signals to individual turbines. The controllers at the turbines include a fatigue life usage estimator which estimates a measure of the fatigue life consumed by key components of the turbine. If this measure exceeds a target value for any component, over-rating is prevented at that turbine.

Abstract: A method of generating a control schedule for a wind turbine is provided, the control schedule indicating how the turbine maximum power level varies over time, the method comprising: receiving input indicative of a target minimum wind turbine lifetime; determining a value indicative of the current remaining fatigue lifetime of the wind turbine or one or more turbine components, based on measured wind turbine site and/or operating data; and varying a parameter of an initial predefined control schedule that specifies how the turbine maximum power level varies over time. The parameter is varied by: (i) adjusting the parameter of the initial predefined control schedule; (ii) estimating the future fatigue lifetime consumed by the wind turbine or the one or more turbine components, over the duration of the varied control schedule, based upon the varied control schedule; and (iii) repeating steps (i) and (ii) until the estimated future fatigue lifetime consumed by the wind turbine or each of the one or more turbine components is sufficient to allow the target minimum wind turbine life to be reached.
