摘　　要：为了实现双馈风力发电系统在额定风速以下运行时发电功率的最大输出与平稳运行,提出一种电流内环与自抗扰控制(ADRC)速度外环的控制方式,使双馈风力发电机(DFIG)电流与转速能快速响应风速变化,进行最大功率追踪。仿真分析验证了ADRC控制具备优良的抗干扰性能与应变性,能够实现风力发电系统的最大功率追踪。Although the doubly fed-wind power generation system operates below the rated wind speed,the maximum output and stable operation need to be maintained.In order to realize this goal,a control mode of current inner loop and active disturbance rejection control(ADRC)speed outer loop is proposed,which makes the current and speed of doubly-fed induction generator(DFIG)quickly respond to the wind speed changes and conduct maximum power tracking.Simulation results show that ADRC has excellent anti-interference performance and adaptability,and can realize maximum power tracking of wind power generation system.
