Grid connected frequency control method of AC excitation variable speed constant frequency wind turbine

Abstract

Aiming at the problem that the current grid connected frequency control effect of wind turbines is poor, the grid connected frequency control method of AC excited variable speed constant frequency wind turbines is proposed, the virtual inertia control method of variable speed wind turbines is optimized, the power oscillation damping control algorithm of AC excited variable speed wind turbines is improved, and the grid connected frequency control process of variable speed constant frequency wind turbines is simplified. Finally, it is confirmed by experiments, The grid connected frequency control method of AC excited variable speed constant frequency wind turbine generator has high practicability and fully meets the research requirements.
