    摘要： Systems and methods of autonomous farm-level control and optimization of wind turbines are provided. Exemplary embodiments comprise a site controller running on a site server. The site controller collects and analyzes yaw control data of a plurality of wind turbines and wind direction data relating to the plurality of wind turbines. The site server determines collective wind direction across an area occupied by the plurality of wind turbines and sends yaw control signals including desired nacelle yaw position instructions to the plurality of wind turbines. The site controller performs wake modeling analysis and determines desired nacelle positions of one or more of the plurality of wind turbines. The desired nacelle yaw position instructions systematically correct static yaw misalignment for all of the plurality of wind turbines. Embodiments of the disclosure provide means to perform whole site or partial site level controls of the yaw controllers of a utility scale wind turbine farm. The overall effect of the coordinated yaw control of wind turbines across the whole or partial site is intended to keep the wake loss of the wind turbines from the upstream wind turbines to the minimum and to maximize the production of turbines that are not waking other turbines.

    摘要： Wind turbine comprising a rotor, comprising at least a first blade, and a supporting structure for supporting said rotor up in the air; wherein said first blade is arranged to rotate in a rotor plane around a rotor axis of the rotor and wherein said first blade is rotatable by a blade pitch driving mechanism around a blade pitch axis that is substantially parallel to a longitudinal axis of the blade, wherein said rotor axis is movable in at least one of a rotational tilt direction, a rotational yaw direction and a fore-aft translational direction and wherein the wind turbine further comprises a controller for controlling the wind turbine by varying an induction factor of the first blade over time while the rotor rotates around its rotor axis, wherein the controller is further arranged for varying said induction factor of the first blade by controlling the blade pitch driving mechanism for applying an oscillatory blade pitch rotation to the first blade, and by inducing an oscillatory motion of the rotor axis in the at least one of the rotational tilt direction, the rotational yaw direction and the fore-aft translational direction.

    摘要： Systems, methods, and non-transitory computer readable media including instructions for synchronizing a plurality of geographically-associated fluid turbines. Synchronizing a plurality of geographically-associated fluid turbines includes receiving first signals indicative of a phase of a rotational cycle of first rotating blades of a first turbine configured to generate a downstream fluid flow; receiving second signals indicative of a phase of a rotational cycle of second rotating blades of a second turbine configured to receive at least a portion of the downstream fluid flow and generate a differential power output; determining from the first and second signals that greater aggregate power output is achievable through blade phase coordination; determining a phase correction between the first and second rotating blades based on the first and second signals to achieve the greater aggregate power output; calculating coordinating signals based on the phase correction; and outputting the coordinating signals to impose the phase correction.
