    • The present invention discloses a method and system that are used to determine the service life endpoint and evaluate the current historical service life. The current historical service life evaluation method comprises: generating the load waveform of the driver according to the load information and movement position information of the transmission mechanism; obtaining the weighted coefficient of the current historical service life of the transmission mechanism according to said load waveform of the driver, and using the weighted coefficient to perform the weighted calculation on the current initial historical service life of the transmission mechanism to obtain the current historical service life of the transmission mechanism. In the method to determine the service life endpoint of the transmission mechanism, the initial value of the previous cumulated historical service life is preset; the current historical service life is added to the previous cumulated historical service life, and the resulting value is compare with the preset estimated service life of the transmission mechanism to determine whether this transmission mechanism reaches its service life endpoint. The technical solution of the present invention can increase the accuracy of the estimation made on the historical service life of the transmission mechanism.

    • 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.
