摘要： A system and method are provided for determining deflection of a tower of a wind turbine, the wind turbine including a nacelle with a machine head and a rotor atop of the tower. A fixed location relative to the tower is established, and a total deflection of a geographic location (“geo-location”) of the fixed location is determined. Components of the total deflection are determined that are generated by non-thrust loads acting on the tower. The non-thrust loads deflection components are subtracted from the total deflection to determine a thrust loads deflection component corresponding to deflection of the tower from operational thrust loads on the rotor.

摘要： A method and associated system are provided for determining a yaw heading (θheading) 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 (βrover) 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 (θheading) is computed from a difference between the angle () and the angular offset (βrover) of the rover receiver.

摘要： A system and method are provided for controlling a wind turbine. Accordingly, a controller of the wind turbine determines a thermal gradient of the tower due to solar heating. The controller also determines a displacement of a reference point of the wind turbine from a nominal position resulting from a thermal expansion of a portion of the tower. The displacement includes a displacement magnitude and a displacement direction. The displacement direction is in a radial direction opposite of a maximal peak of the thermal gradient. Additionally, the controller determines a correction factor corresponding to the displacement and a setpoint for a component of the wind turbine based, at least in part, on the correction factor. Finally, an operating state of the wind turbine is established based, at least in part, on the setpoint.

摘要： A system and method are provided for determining a geographic location of a tower top pivot point (TPP) of a wind turbine tower having a nacelle that includes a machine head and rotor at a top thereof. At least one rover receiver of a global navigation satellite system (GNSS) is configured at a fixed position on the nacelle. A plurality of 360-degree yaw sweeps of the nacelle are conducted and the geo-location signals received by the rover receiver during the yaw sweeps are recorded. With a controller, the geo-location signals are converted into a circular plot and a radius of the plot is determined, the radius being a distance between the rover receiver and the TPP. Based on a GNSS geo-location of the rover receiver and the radius, a geo-location of the TPP is computed.

摘要： A gripping element may be commanded to move to pre-determined robot-frame locations, and markings may be punched into a calibration sample capture substrate at each location. A calibration image may be obtained, and fiducial markings on the gripping element may be detected. A set of calibration regions of interest may be predicted, and the previously punched markings may be detected. A sampling system may then create a mapping transfer function between detected image locations and real-world locations resulting from the commanded locations of the gripping element when the markings were punched. An indication may subsequently be received that a biological sample capture substrate is ready to be processed. An image of the sample capture substrate may be obtained, and the fiducial markings may be detected. Based on those image locations and the mapping transfer function, biological sample portions may be automatically taken from the sample capture substrate.
