Estimating the term…
A control method and a wind turbine for adaptively adjusting the operation of the wind turbine to maintain maximum power production during degraded conditions. The control system has an estimator module that determines a scaling factor based on the current set of control signals and at least the current set of measurement of the operating parameters. The scaling factor is transmitted to a control module which scales at least one aerodynamic property of the rotor based on this scaling factor. The control module further determines the ideal settings for the control signals based on the scaled aerodynamic properties. The present control method scales the aerodynamic properties to provide a better representation of the actual degraded aerodynamic properties.
A method for controlling the operation of a wind turbine having at least two pitchable wind turbine blades rotary connected to an electrical generator, the method comprising the steps of:
A wind turbine comprising a wind turbine tower, an electrical generator arranged on top of the wind turbine tower, a rotor with at least two wind turbine blades rotatably connected to the generator, and a control system configured to control the operation of the wind turbine based on one or more control signals, where the control system is configured to determine a degradation value indicative of the aerodynamic degradation of the wind turbine blades and to adapt the operation of the wind turbine based on this degradation value, wherein the degradation value is a scaling factor and the control system is configured to scale at least one control parameter indicative of the aerodynamic properties of the wind turbine blades in an undegraded state based on this scaling factor.
A wind turbine system comprising one or more wind turbines, wherein each wind turbine comprises a local control system configured to control the operation of that wind turbine, where each local control system is configured to communicate remotely with a remote control system, wherein the remote control system is configured to adapt the operation of at least one of the one or more wind turbines based on one or more control signals, where said remote control system is configured to determine a degradation value indicative of the aerodynamic degradation of the wind turbine blades and to adapt the operation of the wind turbine based on this degradation value, wherein the degradation value is a scaling factor and said remote control system is configured to scale at least one control parameter indicative of the aerodynamic properties of the wind turbine blades in an undegraded state based on this scaling factor.
