Abstract: The control principle of wind power generation for the small vectial axis wind turbine generator was introduced in this paper. Aiming at the shortcomings of the traditional climbing search method, designed a new variable step length perturbation of MPPT. Compared with the traditional climbing method, the new method can more effectively search the maximum power point, and able to maintain stable running near the maximum power point. And its conducive to the stability of the system. Then, the control system was simulated with Matlab/Simulink, and verified the feasibility of the designed scheme.
