Embodiment 1
[0031] Embodiment 1: see attached figure 1 , a wind optimization method based on vibration and inclination, including the following steps: S1 uses a dual-axis inclination sensor to monitor the inclination angle θ projected by the deflection of the fan tower on the x-axis and y-axis directions when the wind speed is stable, so as to judge the wind direction ;S2 uses a dual-axis vibration sensor to monitor the components of the vibration amplitude of the wind turbine tower projected on the x-axis and y-axis when the wind speed is unstable, so that the wind direction can be obtained according to vector synthesis; S3 feeds back the identified wind direction data to the wind turbine yaw system, the wind turbine yaw system makes a judgment, adjusts the position of the blades, and realizes the wind optimization of the wind turbine. Adjust the windward angle of the wind turbine head in time to ensure the zero yaw of the wind turbine head against the direction of the wind.
