Patent number: 11428208Abstract: 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.Type: GrantFiled: August 17, 2020Date of Patent: August 30, 2022Assignee: VESTAS WIND SYSTEMS A/SInventors: Chris Spruce, Chakradhar Byreddy, Kelvin Hales, Judith Turner

Patent number: 10975843Abstract: A wind turbine, power plant and associated method of controlling a wind turbine is provided. Data is obtained that identifies, based on forecast data, one or more future periods of time during which it would be desirable to over-rate the wind turbine, and measures of the fatigue life consumed by one or more turbine components are determined. The total fatigue life consumed by the one or more turbine components is limited prior to the one or more periods of time by controlling the power output of the wind turbine, in advance of the one or more periods of time, based upon the measure of the fatigue life consumed by the one or more turbine components.Type: GrantFiled: June 22, 2016Date of Patent: April 13, 2021Assignee: VESTAS WIND SYSTEMS A/SInventors: Chris Spruce, Kelvin Hales, Judith Turner

Data is obtained that identifies, based on forecast data, one or more future periods of time during which it would be desirable to over-rate the wind turbine, and measures of the fatigue life consumed by one or more turbine components are determined. The total fatigue life consumed by the one or more turbine components is limited prior to the one or more periods of time by controlling the power output of the wind turbine, in advance of the one or more periods of time, based upon the measure of the fatigue life consumed by the one or more turbine components. For example the overall rate of consumption of fatigue life by the one or more turbine components may be reduced prior to the one or more periods of time commencing. The wind turbine is then over-rated during the one or more identified periods. A corresponding wind turbine and wind power plant controller is also provided.Type: ApplicationFiled: June 22, 2016Publication date: July 5, 2018Inventors: Chris SPRUCE, Kelvin HALES (DECEASED), Judith TURNER

Patent number: 9644609Abstract: 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.Type: GrantFiled: September 28, 2012Date of Patent: May 9, 2017Assignee: VESTAS WIND SYSTEM A/SInventors: Judith Turner, Chris Spruce, Robert Bowyer

Patent number: 9599096Abstract: 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 electricity pricing data, power plant age and operator demand. This may comprise a schedule of output set point changes which effect seasonal or intraday changes in electricity prices or which reflect aging of the power plant. It may also reflect the price of electricity on spot or futures markets. Once the over-rating of the power plant has been set, the output may be increased by over-rating individual turbines or operating turbines at rated power if the sum of the rated outputs of the turbines exceeds or is equal to the new power plant output set point.Type: GrantFiled: September 30, 2011Date of Patent: March 21, 2017Assignee: VESTAS WIND SYSTEMS A/SInventors: Christopher Spruce, Judith Turner, Martin Evans, Robert Bowyer

Patent number: 9018782Abstract: Wind turbines of a wind power plant may be selectively over-rated by measuring the difference between the nominal and actual power plant outputs and deriving an over-rating request signal based on that difference which is sent to each turbine. The same value may be sent to each turbine. Alternatively, each turbine may be given its own over-rating amount based on an optimization of the turbine. Over-rating may also be used when external economic factors such as energy costs are sufficiently high to out-weigh any potential harmful effect of over-rating. The fatigue lifetime of turbines and their critical components may also be taken into account when deciding whether and to what extent to implement an over-rating command.Type: GrantFiled: September 30, 2011Date of Patent: April 28, 2015Assignee: Vestas Wind Systems A/SInventors: Ian Couchman, Christopher Spruce, Judith Turner, Martin Evans, Robert Bowyer
