METHOD FOR CONTROLING MPPT USING WIND SPEED ESTIMATION OF WIND POWER GENERATION SYSTEM |
摘要 |
The present invention relates to an MPPT control method through estimating wind speed of a wind power generation system which comprises the steps: (a) deriving a rotational energy of a blade; (b) deriving a tip speed ratio from the rotational energy of the blade; (c) deriving a pitch angle and the tip speed ratio of an efficiency coefficient as a non-linear function and approximating the derived non-linear function to be a third degree polynomial; (d) deriving the sum of a squared error; (e) deriving the sum of the squared error as a fourth degree polynomial; and (f) estimating current wind speed by deriving a solution to the third degree polynomial.
