The invention discloses an anti-
typhoon operation control method of a
wind power generator group, including:
typhoon forecast signals are received; before the coming of a
typhoon, blades are feathered, the generator cabin is controlled to actively drift and assure the
tail part of the generator cabin of facing to wind, thus releasing a drift
brake and stopping; when the typhoon comes, by the function of the
tail rudder of the blades, the windward angle of the
tail part of the generator cabin is continuously adjusted, thus realizing a free drift of the generator cabin according to
wind direction. Due to the
feathering of blades before the coming of the typhoon, by controlling the active drift of the generator cabin, the head part of the generator cabin rotates to downwind direction from where the typhoon comes, thus the free drift of the generator cabin is well prepared by the tail part of the blades; when the typhoon comes, the free drift of the generator cabin is realized by depending on the aerodynamical moment applied to the blades, and the windward angle of the tail part of the generator cabin is continuously adjusted by the function of tail
rudder of the blades to reduce wind load, blade root
bending moment, and overturning moment applied to the generator group, thus preventing any damage to the generator group. On the basis, the invention additionally discloses an anti-typhoon operation control device of a
wind power generator group and a
wind power generator group using the device.
