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.

Abstract: 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.

Abstract: Methods for calculating a maximum safe over-rated power demand for a wind turbine operating in non-standard conditions include the steps of determining a value indicative of a risk of exceeding an ultimate design load during operation in a standard operating condition, and establishing a maximum over-rated power demand corresponding to a maximum power that the turbine may produce under the non-standard operating condition without incurring an increased risk of exceeding the ultimate design load, with respect to operation in the standard condition. A method of over-rating a wind turbine, a wind turbine controller, a wind turbine and a wind power plant are also claimed.

Abstract: A method is disclosed for controlling a wind turbine generator to provide power above a rated level based upon operational constraints. The wind turbine includes an over-rating controller that calculates an over-rating power demand in response to the values of one or more operating parameters, and communicates this demand to the generator. An over-rating command value is calculated according to set points of the operating parameter(s), the calculation taking into account the extent to which the operating parameter differs from these set points. The over-rating command value may vary proportionately with the difference between the operating parameter and the associated set point. If multiple operating parameters are used then the over-rating power demand may correspond to the minimum over-rating command value. Furthermore, the power demand maybe communicated to wind turbine generators individually, or may be calculated for a wind turbine park.

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.
