Problems solved by technology

[0005] As a result, even a properly calibrated wind vane and / or sonic wind sensor, at least in some wind conditions, can cause the wind turbine to yaw error and thus prevent the wind turbine from operating optimally

Embodiment Construction

[0036] figure 1 A wind turbine 1 with a tower 2 and a nacelle 3 is shown. The rotor 4 is mounted on the nacelle 3 . The nacelle 3 is connected to the tower 2 via a yaw drive 5 capable of rotating the nacelle 3 in the horizontal plane. The yaw drive 5 is part of a yaw system comprising a yaw control device which controls the motor and the interrupt mechanism. The yaw control device may take input from the wind turbine control system and / or directly from the wind vane 6 . The wind vane 6 has wings 15 that change position relative to the wind direction and a base 12 connected to the nacelle. exist figure 1 In the illustrated embodiment, the wind vane 6 is located on the nacelle 3 behind the rotor 4 with respect to the wind when the wind turbine is running. This is the normal position for vane 6. This also means that the wind vane 6 is in a downwind direction relative to the rotor 4 , so changes and disturbances in the wind generated by the rotor 4 will affect the wind vane ...

Abstract

The invention regards an apparatus for adjusting the yaw of a wind turbine adapted for mounting on a wind turbine comprising, a system for measuring the wind direction adapted, via a control signal, to control the yaw angle of the wind turbine based on the wind direction, and a wind sensor system adapted to determine the yaw error of the wind turbine, and means for modifying the control signal based on the yaw error determined by the wind sensor system.

Description

technical field [0001] The invention relates to a device and a method for adjusting the yaw of a wind turbine. Background technique [0002] In wind turbines it is necessary to control the orientation of the wind turbine rotor relative to the wind, the so-called yaw. Conventional wind turbines have a nacelle mounted on a tower, where the nacelle can be rotated appropriately towards the wind direction via a yaw system. Yaw is also known as azimuth. The nacelle has a generator connected by a shaft to the rotor of the wind turbine so that the yaw drive can properly control the orientation of the rotor. Optimum performance of the wind turbine is obtained when the rotor axis is parallel to the wind direction, power output is maximized and / or loads are minimized. If this optimal position is not obtained, the wind turbine is considered to have "yaw error". Yaw error is expressed as its angular magnitude from the optimal position. [0003] Conventionally, one or more wind vanes...
