Abstract

The invention discloses a method and a device for dynamically correcting the yaw deviation of a wind turbine generator system to the wind, By dynamically obtaining the optimal yaw wind deviation, Theoriginal wind direction signal can be compensated by the dynamic correction device, and the actual wind direction angle at the fan impeller can be corrected, so that the measurement accuracy of the wind direction at the fan impeller can be improved, the electric quantity of the wind turbine generator system can be improved, the unbalanced load of the yaw system can be reduced, and the service lifeof the yaw system can be prolonged. The problem that the optimal angle of wind deviation can not be obtained is solved by analyzing the data collected on site, including data pre-processing and dynamic processing.

Description

technical field [0001] The present invention relates to the technical field of wind power, in particular to a method and device for dynamically correcting the yaw-to-wind deviation of a wind turbine. Background technique [0002] In order to ensure the efficient operation of wind turbines, large wind turbines use a yaw system. According to the wind speed and wind direction data collected by the wind measurement system, the yaw control system keeps the impellers of the wind turbines in the windward state (when the impellers of the wind turbines are facing the wind). When facing the wind, θ=0, the unit captures the maximum wind energy and generates the maximum electric energy through the transmission system). [0003] [0004] Among them, P m - Wind capture power, c p -wind energy utilization coefficient, ρ-air density, A-swept area, V wind -wind speed, θ-yaw-to-wind deviation; λ-tip speed ratio, β-pitch angle; [0005] However, due to the initial installation error of ...
