Abstract

The invention discloses a device and method for obtaining the relative cabin average wind direction of a fan, and belongs to the field of wind power generation technologies and wind energy data errorcorrection methods. The device comprises a data detection device used for collecting relative cabin wind direction data and a fan twisting cable value, and a main controller used for correcting the collected relative cabin wind direction data and converting the corrected relative cabin wind direction data to obtain a relative cabin average wind direction. The method comprises a data acquisition step, a wind direction correction step and a conversion step. According to the method for obtaining the relative cabin average wind direction of a fan, the accurate relative cabin average wind directioncan be obtained, and therefore the yaw wind alignment precision of the fan is improved, wind energy capture of a fan wind wheel is improved, the power generation amount of the fan is increased, and apower curve is improved.

Description

technical field [0001] The invention belongs to the field of wind power generation technology and wind energy data error correction method, and in particular relates to a device and method for obtaining the average wind direction of a fan relative to a nacelle. Background technique [0002] The main controller of the wind turbine controls the yaw of the wind turbine against the wind according to the average wind direction relative to the nacelle, and yaws in the direction that reduces the absolute value of the wind direction relative to the nacelle. The accuracy of the average wind direction relative to the nacelle will directly affect the wind effect of the wind turbine yaw. At present, the calculation method of the average wind direction of the fan relative to the nacelle is as follows: the main controller collects and stores the instantaneous wind direction data relative to the nacelle, and then calculates the average wind direction relative to the nacelle according to the...
