Abstract: A system for operating a wind turbine farm, comprising a plurality of wind turbines (1) having at least one ambient sensor (7) and optionally at least one operating sensor (9). The wind turbines are in communication with a remote control unit(2) which in turn is connected to at least one database(3) in which the ambient data and, optionally, the operating data are stored. The remote control unit(2) selects an upwind wind turbine and determines a first power output thereof, and further selects a downwind wind turbine and determines a second power output thereof. The remote control unit(2) determines a relationship between the first and second power outputs which is then used to determine a reduced operating level of the selected upwind wind turbine. A method thereof is also provided.

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: A method for controlling the operation of a wind turbine may generally include monitoring a current yaw position of a nacelle of the wind turbine, wherein the current yaw position is located within one of a plurality of yaw sectors defined for the nacelle. In addition, the method may include monitoring a wind-dependent parameter of the wind turbine and determining a variance of the wind-dependent parameter over time, wherein the variance is indicative of variations in a wind parameter associated with the wind turbine. Moreover, the method may include determining at least one curtailed operating setpoint for the wind turbine when the variance exceeds a predetermined variance threshold, wherein the curtailed operating setpoint(s) is determined based at least in part on historical wind data for the yaw sector associated with the current yaw position.

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.
