Abstract

The present invention provides a control method, a central controller and a system for a wind turbine. The control method for a wind turbine comprises: measuring the actual values, including a position signal Pact, of each of the blades of the wind turbine; outputting pre-set values, including a pre-set position signal Pset, for controlling the blades according to the actually measured position values of the blades; outputting the lag speed between two adjacent blades according to the actually measured values of each of the blades; and revising the pre-set values and outputting revised values, including the revised position value P'set, capable of controlling the blades of the wind turbine according to the actually measured values and the lag speed of the blades. The controller of the present invention comprises: a control unit for outputting a pre-set value according to the actually measured value of a blade; an asymmetry predicting unit for outputting a lag speed between the two adjacent blades according to the actually measured values; and an asymmetry adjusting unit capable of revising the pre-set value. By connecting the central controller of the present invention with a pitch controller of the wind turbine, it is capable of effectively preventing asymmetry failure in the wind turbine from occurring at low cost and with good effect.
