  • Publication number: 20240401565
    Abstract: Systems and methods are provided for the control of a wind turbine. Accordingly, a wind classification module of a controller determines a current aerodynamic state of the wind resource based, at least in part, on a current operational data set of the wind turbine. The current operational data set is indicative of a current operation of the wind turbine. A configuration intelligence module of the controller then generates an estimated configuration for a turbine estimator module and a predictive control configuration for a predictive control module based, at least in part, on the current aerodynamic state. An operation of the wind turbine is emulated via the turbine estimator module to generate a control initial state for the predictive control module. The predictive control module then determines a predicted performance of the wind turbine over a predictive interval based on the control initial state and the predictive control configuration.

  • Patent number: 11703033
    Abstract: A method and associated system are provided for determining a yaw heading (?heading) of a wind turbine, the wind turbine having a tower and a nacelle that includes a machine head and rotor at a top thereof. The method includes configuring a single rover receiver of a global navigation satellite system (GNSS) at a fixed position relative to the nacelle. A GNSS geographic location of a tower top pivot point (TPP) of the wind turbine is determined, as well as an angular offset of the rover receiver (?rover) relative to a centerline axis of the nacelle. Based on the GNSS geo-location of the TPP and a GNSS geo-location of the rover receiver, an angular vector () relative to North of a line between the TPP and the rover receiver is determined. The yaw heading (?heading) is computed from a difference between the angle () and the angular offset (?rover) of the rover receiver.

  • Patent number: 11408396
    Abstract: A wind turbine and method are provided for defining a plurality of thrust limits for the wind turbine located at a site and having a rotor with rotor blades, wherein the thrust limits define values of aerodynamic thrust on the rotor not to be exceeded in operation. The method includes providing a wind speed distribution representative for the site and defining one or more isolines of constant turbulence probability representing a turbulence parameter as a function of wind speed. The isolines correspond to quantile levels of turbulence of the wind speed distribution and the turbulence parameter is indicative of wind speed variation. The turbulence parameter is determined by continuously measuring wind speed upstream of the rotor with an active sensing system and calculating the wind speed variations from the measured wind speed. Turbulence ranges are defined with respect to the isolines and thrust limits are defined for the turbulence ranges.
