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 the maximum number of times that each of one or more turbine components are to be replaced over the remaining lifetime of the turbine; determining a value indicative of the current remaining fatigue lifetime of the turbine, or one or more of the 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 varying is performed by: (i) adjusting the parameter of the initial predefined control schedule; (ii) estimating the future fatigue lifetime consumed by the wind turbine, or one or more turbine components, over the duration of the varied control schedule, based upon the varied control schedule and accounting for the replacements of the one or more turbine components; 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 a target minimum wind turbine life to be reached.
