Abstract

The invention provides a method for obtaining an inherent yaw error angle of a wind generating set. The method comprises the following steps of: 1) obtaining an absolute value of the inherent yaw error angle according to a theoretical value and a detection value of the yaw error angle of the wind generating set; and 2) judging the inherent yaw error angle is negative or positive to obtain a numerical value of the inherent yaw error angle of the wind generating set. By the method for obtaining the inherent yaw error angle of the wind generating set provided by the invention, the inherent yaw error angle of the wind generating set can be obtained, so error control can be carried out in a yawing process, the influence of the inherent yaw error angle on yawing of the wind generating set is reduced or even eliminated, the yawing control of the wind generating set is relatively accurate, the wind generating set can always face a wind direction, and generation efficiency is improved.

Description

technical field [0001] The invention relates to wind power generation technology, in particular to a method for obtaining the inherent yaw error angle of a wind turbine, a yaw control method, a device, and a wind power generating set. Background technique [0002] In the field installation process of large-scale wind turbines, due to the limitation of assembly process and the difficulty of high-altitude operation, it is difficult to accurately calibrate the initial position of the wind turbine nacelle and the initial position of the wind vane in actual operation. At present, when installing units in wind farms, commissioning personnel generally use visual inspection to calibrate the initial position of the wind vane based on experience, which leads to an inherent deviation between the initial position of the wind turbine nacelle and the initial position of the wind vane. In addition, since most of the wind vanes currently used in wind farms are mechanical wind speed and dire...
