    Abstract: Determination of Wind Turbine Configuration The present invention relates to a method and computer system for determining a configuration of a wind turbine of a given wind turbine type, the method comprising the steps of: storing in a database a plurality of combinations of physical and control parameters of the wind turbine that can be varied; determining a plurality of wind flow characteristics at a target location; applying a function which defines a relationship between a performance parameter, a fatigue life estimation, the combination of physical and control parameters and the plurality of wind flow characteristics, to at least some of the plurality of combinations in the database to determine values of the performance parameter and the fatigue life estimation for those combinations; and selecting one of the combinations of physical and control parameters as the configuration of the wind turbine for the target location on the basis of the performance parameter and fatigue life estimation values.

    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.

    Abstract: A control schedule for a wind turbine indicates how the turbine maximum power level varies over time. Generating the 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 is disclosed for controlling a wind turbine generator to provide power above a rated level. The wind turbine includes one or more electrical components that conduct current from the internal generator to supply the external grid. The control method calculates the maximum current that the electrical components can carry at the ambient temperature. The calculated current is combined with a measurement of the voltage and an estimate of reactive power in the system to give a maximum power at which the wind turbine can operate without the maximum allowable current being exceeded for the electrical components. The electrical components may be housed in the main electrical panel of the wind turbine.

    Abstract: The present invention relates to a method and control system comprising at least one cable temperature sensor for measuring cable temperature values for at least one power collection cable (50, 55) connected to a wind turbine (20) and a controller (110) arranged to generate and output an overrating control signal to the wind turbine (20). The output overrating control signal sets an amount by which the power output of the wind turbine (20) is to be overrated. It is determined whether the measured cable temperature values exceed a temperature set point and modifying the overrating control signal to reduce the amount of overrating if the temperature set point is exceeded.

    Abstract: Methods and systems for reducing an output power of a group of wind turbines are provided. A measure of life usage by at least one component of each of a plurality of the turbines is determined, and is compared to a threshold value for life usage for the component. Power output is preferentially reduced from those turbines having at least one component for which the measure of life usage exceeds the corresponding threshold value.
