具有可选风扇节距控制的翼式轴流风扇。
对于控制系统,建立了传感器、节距调节器、转速PI控制器、转矩PI控制器、节距PI控制器等的数学模型。
To the control system, The mathematics model of transducers, blade actuator, PI controller to rotate speed, PI controller to the torque, PI controller to the blade angle are established.
数字仿真表明,在风速低于额定风速时变速运行捕获能量比恒速运行捕获能量大;节距调节控制可以很好地使输出功率稳定在额定功率左右。
The simulation results indicate that wind turbine is operated at maximum power coefficient with variable-speed mode and the output power of generator is kept around rated power with pitch control.
