Research on Control Strategy of Synchronous Permanent Magnet Direct Drive Wind Power System Based on the Best Given Power

Direct drive wind power generation system which without the need for a gearbox have developed and applied in the wind farm.This paper studied the characteristics of generators and turbines,the wind energy control strategy based on optimal power given maximum is proposed.By closed-loop control of the generator,this method can realize the output power in accordance with the optimum power output curve to achieve maximum wind power tracking;And the control strategy of the permanent magnet direct drive wind power system＇s dual-PWM converter is studied.A direct drive wind turbine integrated model is built,the system is able to achieve grid control based on wind maximum power point tracking,the simulation results verify the correctness of the control system.
