    摘要: Embodiments of the invention generally relate to using remote sensing equipment such as a Light Detection and Ranging (LIDAR) device to detect wind characteristics for use by wind turbines of a wind park. A wind park controller may received raw wind data from the remote sensing device and determine one or more turbines that can use the raw wind data. The raw wind data may be converted to customized data for each of the one or more wind turbines. Upon being provided the customized wind data, the one or more wind turbines may adjust one or more operational characteristics to improve power production or avoid damage to turbine components.

    摘要: Wind energy systems and devices comprise a nacelle, a rotor driven alternator housed in the nacelle, a rotor connected to the alternator, and a load control system in communication with the alternator. The rotor includes a rotor hub and three or more rotor blades, and each blade has a foil shape and is connected to the rotor hub by a full foil attachment mechanism. The alternator is configured to operate at low rpm and to increase rotation speed without a step-up mechanism. The load control system is configured to anticipate changes in wind speed and adjust alternator load such that when wind speed increases the load control system adjusts the alternator load to optimize rotor rpm and optimize tip-speed ratio.

    摘要: A wind turbine includes a number of blades and an optical measurement system comprising a light source, such as a laser, an optical transmitter part, an optical receiver part, and a signal processor. The light source is optically coupled to the optical transmitter part, which includes an emission point for emitting light in a probing direction. The optical receiver part comprises a receiving point and a detector. The optical receiver part is adapted for receiving a reflected part of light from a probing region along the probing direction and directing the reflected part of light to the detector to generate a signal used to determine a first velocity component of the inflow. The emission point is located in a first blade at a first radial distance from a center axis, and the receiving point is located in the first blade at a second radial distance from the center axis.

    摘要: Method of operating a wind turbine comprising a plurality of blades rotatable along their longitudinal axes using a pitch mechanism, and comprising one or more movable trailing edge surfaces. The method includes predicting, at a first moment in time, a high load for one or more of the blades at a second moment in time. The method further comprises actuating on one or more of the movable trailing edge surfaces of these blades such that the trailing edge surfaces have a wider range of control to counteract the predicted high loads before the second moment in time, and simultaneously pitching the blades such as not to negatively affect the operation of the wind turbine. The method furthermore comprises, at the second moment in time, actuating the one or more movable trailing edge surfaces of the at least one or more blades to counteract the high loads.

    摘要: A wind turbine power management system and method includes one or more wind turbines at a wind farm and one or more laser sources used to measure wind conditions remote from the wind farm. The laser sources may be collocated with the wind turbines, and are able to measure wind conditions at various predetermined ranges from the wind turbines. The laser sources measure wind conditions at locations that provide 10 to 20 seconds of advance notice, and also at locations that provide 50 to 100 seconds of advance notice. Wind condition at locations that provide 500 or more seconds of advance notice are also measured using remote laser sources.
