Abstract

This paper proposes a power stable control strategy combine pitch control with torque control for direct-drive permanent magnet wind generation system in above-rated wind speed conditions. A Pitch controller based on fuzzy logic control is designed to keep the rotor speed from exceed its limit. Torque controller set electromagnetic torque reference according to the rated electrical power and rotor speed, and control the current to make the actual torque track torque reference to regulate the electrical power. Compared simulation results show that the proposed control strategy could better inhibiting power fluctuations.
