Abstract :
This paper presents sensorless rotor-flux-oriented control algorithms for the PMSG used in the direct drive wind generation system with a back-to-back current source converter. The proposed algorithms are based on phase-lock-loop and model reference adaptive system methods. These algorithms are analyzed, compared and verified by the simulation and experiment. The simulation and experiment results show that the PLL method is simpler, but more accurate, and has a faster dynamic performance than MRAS method.
