基于自抗扰控制策略的直接转矩风力发电系统研究OA

In response to the problem of the system failing to track the maximum power point effectively in the permanent magnet direct drive wind power generation system with direct torque control,an active disturbance rejection control strategy is proposed to be added to the turbine side control structure of the wind power generation system to improve system performance.Based on the mathematical model of wind turbines and permanent magnet synchronous wind turbines,combined with the basic model of active disturbance rejection control(ADRC),a generator active disturbance rejection speed loop is constructed.Finally,the proposed control strategy was simulated and analyzed using software Matlab/Simulink.Compared with the traditional PI control direct torque wind power system,the introduction of auto disturbance rejection control strategy improves the overall anti-interference ability and tracking performance of the system.
