چکیده
This work presents a Comparative study of closed and open loop control system using UPF control strategy for standalone variable speed wind turbine permanent magnet synchronous generator employing space vector modulation voltage source converter. The mechanical energy required to drive the generator is obtained from variable speed wind turbine. Three phase PMSG is excited from three phase VSC. The control strategy has been developed for maintaining DC link voltage constant based on the principle to shape the line current as the line voltage to ensure high power factor operation of the converter without using three phase PLL. Discussing the advantage of closed loop control over open loop control. The simulation study has been carried out using MATLAB/SIMULINK. Keywords——Open loop system, SVMspace vector modulation, Variable speed wind turbine, VSI-voltage source inverter
