Methods and systems for generating wind turbine control schedules
First Claim
1. A method of generating a control schedule for a wind turbine, the method comprising:
- receiving an input indicative of a maximum number of times that each of one or more components of the wind turbine are to be replaced over a remaining lifetime of the wind turbine;
determining, based on one or both of site data and operating data of the wind turbine, a value indicative of a current remaining fatigue lifetime of the wind turbine or of one or more of the components; and
generating a control schedule for the wind turbine that specifies how a maximum power level of the wind turbine varies over time, wherein generating the control schedule comprises;
i) adjusting a parameter of a current iteration of the control schedule to generate a varied control schedule;
ii) estimating a future fatigue lifetime consumed by the wind turbine, or of the one or more components, over a duration of the varied control schedule, based upon the varied control schedule and accounting for replacements of the one or more components; and
iii) repeating (i) and (ii) until the estimated future fatigue lifetime is sufficient to reach a target minimum wind turbine life of the wind 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 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.

23. A method of generating a control schedule for a wind power plant comprising two or more wind turbines, the method comprising:
-
receiving an input indicative of a maximum number of times that each of one or more components, for each wind turbine of the two or more wind turbines, are to be replaced over a remaining lifetime of the wind turbine; determining, based on one or both of site data and operating data of each wind turbine of the two or more wind turbines, a value indicative of a current remaining fatigue lifetime of the wind turbine or of one or more components of the wind turbine; and generating a control schedule for the two or more wind turbines that specifies how a maximum power level of each wind turbine of the two or more wind turbines varies over time, wherein generating the control schedule comprises; i) adjusting a parameter of a current iteration of the control schedule to generate a varied control schedule; ii) estimating a future fatigue lifetime consumed by the two or more wind turbines, or of the one or more components, over a duration of the varied control schedule, based upon the varied control schedule and accounting for replacement of the one or more components using a site check program that determines loads acting on the one or more components based upon sensor data obtained from sensors of the wind power plant and parameters relating to the wind power plant and to the design of the wind turbine, and includes interactions between the two or more wind turbine; and iii) repeating (i) and (ii) until the estimated future fatigue lifetime is sufficient to reach a target minimum wind turbine life of the two or more wind turbines. - View Dependent Claims (24, 25)
