Automatic calibration method and device for air aligning errors of wind generation set

Abstract

The invention provides an automatic calibration method and device for air aligning errors of a wind generation set. The method includes the steps that historical operation data of the target set in a preset time period are obtained; abnormal data are removed from the historical operation data of the target set; dimensionality reduction processing is conducted on target data, and relation curves of the air aligning errors and the air outlet performance are determined according to the data obtained after dimensionality reduction processing; an inherent air aligning error is determined according to the relation curves of the air aligning errors and the air outlet performance; and a zero parameter in a yaw system of the target set is corrected through the inherent air aligning error. By means of the automatic calibration method and device for the air aligning errors of the wind generation set, the historical operation data of the wind generation set are fully utilized, the inherent air aligning error of the yaw system of the target set is automatically identified by conducting data mining and analyzing on the historical operation data so that the zero parameter in the yaw system can be automatically adjusted through the inherent air aligning error, the adaptive ability of the yaw system of the set is improved, and the actual force applying performance of the set is improved.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a method and device for automatically calibrating the wind error of a wind turbine. Background technique [0002] In recent years, in the wind power industry, the problem of inaccurate wind vane measurement at the tail of the nacelle has gradually attracted the attention of the industry. Improper calibration methods during installation of the wind vane, operational errors of operation and maintenance personnel, disturbances in extreme working conditions such as typhoons, and many other factors may cause the absolute zero position of the wind vane to be non-parallel to the centerline of the cabin, resulting in an "inherent windward error" in the yaw system. As a result, the output power of the unit cannot meet the design requirements.

Problems solved by technology

[0003] In view of this, the present invention provides a method and device for automatic calibration of wind turbine error to solve the problem in the prior art that the absolute zero position of the wind vane is not parallel to the center line of the nacelle due to many reasons, which makes the yaw system exist. The "inherent wind error" leads to the problem that the output power of the unit cannot meet the design requirements. The technical solution is as follows:
