Abstract :
Base on the analysis the mathematical model of the doubly-fed wind turbine and the maximum wind power tracking (MPPT) principle, pointed out the pitch deformation error will affect the effect of MPPT, put forward a new method base on micro pitch and Vary Speed for Extreme Value Search. Field test results show that the proposed method show good dynamic characteristics and tracking capabilities, it can improve the efficiency of wind turbine.
