Abstract
A wind turbine flutter suppression method includes: determining a nacelle-wind direction angle between a wind direction and a nacelle direction; and determining a pitching method for changing pitch angles according to the nacelle-wind direction angle. The pitching method includes a speed-controlled pitching scheme and a pitch-angle-sequence-controlled pitching scheme. The speed-controlled pitching scheme includes regulating pitch angles of blades of the wind turbine according to a rotor speed of the wind turbine to keep the rotor speed within a preset speed range until flutter of the wind turbine is suppressed. The pitch-angle-sequence-controlled pitching scheme includes performing a pitching operation on the pitch angles of the blades of the wind turbine according to preset pitching rules until the flutter of the wind turbine is suppressed.
