Description

Technical Field

[0001] This invention relates to the technical field of wind power generation, specifically to a wind turbine yaw error self-correction device. Background Technology

[0002] A wind turbine is a device that converts wind energy into electrical energy. The yaw system is a crucial component of a wind turbine, working in conjunction with the control system to ensure the turbine is always facing the wind, maximizing wind energy utilization. The wind turbine converts wind energy into mechanical energy, which drives the internal rotor to rotate and generate alternating current.

[0003] Anemometers are an important device in the yaw subsystem of wind turbines. In order to maximize wind power conversion efficiency, current large wind turbines adopt active yaw strategies, which involve actively rotating the nacelle according to the wind direction to make the rotor face the oncoming wind direction.

[0004] According to invention application number 201811346437.5, a height-adjustable wind vane for wind power generation includes a housing. Bearings a are symmetrically engaged on the left and right sides of the lower inner wall of the housing, and both bearings a are sleeved on the outer surface of a rotating shaft a. The right end of the rotating shaft a is fixedly connected to the left side of a turntable. A handle is welded to the right side of the turntable. Two bevel gears a are fixedly connected to the outer surface of the rotating shaft a. When the handle is turned, the turntable rotates, which in turn rotates the rotating shaft a. The meshing of bevel gears a and b rotates the rotating shaft b, causing the threaded column to rotate. This causes the support plate to move upwards, thus moving the wind vane body on the support plate upwards out of the housing. Turning the handle clockwise or counterclockwise moves the support plate up or down, thereby adjusting the height of the wind vane body. This allows for the sensing of wind direction at different heights, providing accurate wind direction information.

[0005] The aforementioned height-adjustable wind vane for wind power generation does not address the problems inherent in existing wind power technology. Since wind turbines are installed and fixed in open areas at a relatively high height, the accuracy of the wind vane will not be affected by different height positions.

[0006] In existing wind turbine applications, offshore wind turbines operate in harsher environments than onshore turbines. After prolonged use, wind vanes may deviate from their intended direction. While numerous compensation methods exist to mitigate this deviation, this requires that most wind vanes in the wind farm be correctly installed. If a large number of wind vanes in a wind farm consisting of several turbines exhibit incorrect pointing, the compensation methods will be unable to accurately compensate for the deviation. Therefore, when installing wind vanes on offshore wind turbines, greater attention should be paid to installation precision and accuracy to minimize installation errors and facilitate subsequent automatic calibration of the wind turbine.
