Abstract
A control method, apparatus and system for anti-vortex induced vibration of a wind turbine are provided. With the method, it is determined whether the wind turbine enters an anti-vortex induced vibration mode; an anti-vortex induced vibration function and triggering a window period is enabled in response to the wind turbine entering the anti-vortex induced vibration mode; and a blade of the wind turbine is adjusted to a preset anti-vortex induced vibration position in the window period, where the window period indicates a minimum time to complete the anti-vortex induced vibration function.
