摘　　要：针对直驱式永磁同步风力发电机组,分别设计了电机侧和电网侧的变换器自抗扰控制器,从而实现在额定风速以下对电机侧的最大风能跟踪控制、电网侧直流电容电压恒定控制。与常规PI控制器相比,采用自抗扰控制器的直驱动式永磁同步发电系统,能够实现对指令转速快速及无超调跟踪、有效抑制风速变化及电网电压扰动对电容电压的影响,具有较为优秀的控制性能。Based on the mathematical model of direct-drive permanent magnet synchronous wind power generation system, the active disturbance rejection controllers （ADRC） are designed for the generator-side converter and the grid-side converter respectively. Using the ADRC, the wind power generation system with dual PWM converter can track maximum power point by the generator-side converter and maintain a constant voltage of DC capacitor by the grid-side converter under rated wind speed. The simulation result shows that comparing with the traditional PI controller, wind power generation system with ADRC can track the reference turbine speed quickly without overshoot. At the same time, voltage disturbance on DC capacitor caused by the variation of wind speed and grid voltage disturbance is effectively restrained. So the wind power generation system with ADRC has outstanding control performance.
