    摘要： Provided is a method for optimizing an operation of a wind farm. The farm includes wind turbines and each can be adjusted via operating settings, and a farm model depicting the wind farm or part thereof is used. The method comprises an optimization sequence using the farm model, with the steps: specifying an optimization wind direction in the farm model for optimizing the operation of the farm for this wind direction; varying operating settings of at least a first leading turbine of the farm model; determining effects of varying the operating settings of the first leading turbine on at least one downstream turbine of the farm model, which is aerodynamically influenced by the first leading turbine, by means of a wake model; determining a total farm result of the farm model; wherein the operating settings are varied so as to optimize the total farm result.

    摘要： A rotary machine for a power system includes a rotary drum having a rotational center shaft, a stationary half gear including a generally circular non-geared portion and a geared portion having gear teeth, and at least one pair of revolving gears formed of two revolving gears symmetrically positioned about the center shaft and configured to simultaneously revolve around the stationary half gear. At least one rack shaft is operably coupled, directly or indirectly, to the revolving gears to reciprocate back and forth upon rotation of the revolving gears, and as the revolving gears revolve around the stationary half gear, one of the two revolving gears is configured to have gear engagement with the geared portion of the stationary half gear, while the other revolving gear is floating over the non-geared portion of the stationary half gear.

    摘要： The invention relates to a method and a wind turbine system reducing, preventing or mitigating vibrations due to wind induced vibrations. The wind turbine system includes a wind turbine tower 102, a sensor arrangement 304 for sensing vibrations of the wind turbine tower, a nacelle 104 mounted to the wind turbine tower via a yaw bearing 310 and a control system 306 for controlling yawing of the nacelle relative to the wind turbine tower. The system is adapted for sensing 402 a vibration of the wind turbine tower using the sensor arrangement, providing 404 an input for the control system in response to the vibration of the wind turbine tower as sensed by the sensor arrangement, and providing 406 an output by the control system based on the input, and yawing 408 the wind turbine nacelle based on the output from the control system, and hereby reducing wind induced vibrations of the tower and nacelle, particularly vortex induced vibrations and/or vibrations due to galloping.

    摘要： The present application discloses novel systems and methods for yawing an autonomous wind turbine. In an embodiment, the wind turbine includes a control system configured to determine a control action signal for a yaw drive mechanism of the wind turbine as a function of the wind condition(s) and as a function of the load condition(s). The control system is configured to monitor change(s) associated with the load condition(s) to determine if the load condition(s) is too high for too long, or in need of attention, before yawing of the wind turbine is initiated or, if the load condition(s) are getting too high, after yawing has been initiated. In another embodiment, the control system includes a load sensor system with proximity sensors arranged adjacent, on, and/or about the main shaft flange of the nacelle or on the rotor blades of the wind turbine.

    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 yaw control device includes a bottom horizontal plate, a top horizontal plate, a first vertical plate, and a second vertical plate. An aperture is positioned between first and second edges of the bottom horizontal plate, and is closer to a third edge of the bottom horizontal plate than to a fourth edge of that plate. A bottom edge of the first vertical plate is attached to a first edge of the bottom horizontal plate. An upper edge of the first vertical plate is attached to a first edge of the top horizontal plate. A bottom edge of the second vertical plate is attached to a second edge of the bottom horizontal plate. An upper edge of the second vertical plate is attached to a second edge of the top horizontal plate. The third edges of the horizontal plates are adapted to rotate about a shaft inserted through the aperture.
