| This thesis based on the new energy wind power generation system, researched on power tracking and control method of micro wind power generation system. A prototype stage is designed to control the power of wind power generation system.This paper analyzes the aerodynamic characteristics of wind turbine power generation system. The wind turbine and PMSG is modeled in mat lab/Simulink, and the algorithm of generator motor speed control is proposed.This paper proposes a DC/DC stage topology which is adapted to the wind power system, and analyzes the feasibility of the current type LLC resonant converter applied in wind power generation system. a current-mode control LLC resonant converter has been designed and algorithm based on the optimal design of the magnetizing inductance parameters has been used.Power control algorithm and wind power system fan speed control algorithms has been designed in this paper. MPPT control strategy is proposed and the feasibility is verified. |
