Abstract
This paper mainly studies the generator side converter of permanent magnet synchronous wind power generation system using dual PWM converter as the main circuit. This paper mainly studies and analyzes the control principle and control mode of generator side PWM in wind power generation system, and models and simulates the motor side converter based on rotor field oriented control. According to the control characteristics of the machine side converter, the specific idea of adopting the PWM vector control strategy is analyzed. The vector control strategy based on feedforward decoupling is proposed. The results of MATLAB / Simulink simulation show that: the PMSM Wind power generation system with vector control strategy can achieve stable power generation operation with variable speed and constant frequency, and can effectively adjust the output power of the power generation system, and the output current has good sinusoidal performance and small harmonic.
