Anti-vortex-induced vibration control method, apparatus, and system for wind generator set

A controller for anti-vortex induced vibration of a wind turbine, comprising:

• an anti-vortex induced vibration mode determination module, configured to determine whether the wind turbine enters an anti-vortex induced vibration mode;
• an anti-vortex induced vibration triggering module, configured to enable an anti-vortex induced vibration function and trigger a window period in response to the wind turbine entering the anti-vortex induced vibration mode;
• and
• an anti-vortex induced vibration execution module, configured to adjust a blade of the wind turbine to a preset anti-vortex induced vibration position in the window period,
• wherein the window period indicates a minimum time to complete the anti-vortex induced vibration function.

A control system for anti-vortex induced vibration of a wind turbine, comprising:

• a pitch system, configured to adjust a position of a blade of the wind turbine;
• and
• a main control system, configured to control an operation of the pitch system,
• wherein the pitch system is further configured to:
• determine whether the wind turbine enters an anti-vortex induced vibration mode;
• enable an anti-vortex induced vibration function and trigger a window period in response to the wind turbine entering the anti-vortex induced vibration mode;
• and
• adjust a blade of the wind turbine to a preset anti-vortex induced vibration position in the window period,
• wherein the window period indicates a minimum time to complete the anti-vortex induced vibration function.
