Abstract :
In view of the buck and boost capabilities of quasi-Z-Source inverter (qZSI), an application of qZSI to a permanent magnet synchronous generator (PMSG) with wind power generation system (WPGS) is presented. The traditional space vector PWM (SVPWM) technique is modified to satisfy the shoot-through characteristic of qZSI. The closed-loop control of shoot-through duty cycle is designed to obtain the desired DC bus voltage. The DC-link boost control and AC-side output control are presented to reduce the impacts of disturbances on grids. Further, some significant simulations are done in MATLAB / SIMULINK. The simulated results verify the validity and superiority of the proposed control strategies, indicating a significant method to enhance the anti-interference performances of wind power generation systems.
