摘要
通过对风力机空气动力学特性的分析,提出了风力机组变速运行最大能量捕获及变桨距控制实现功率稳定的理论依据。详细研究了变速运行控制方法、变桨距机构设计及控制方案。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。
Based on research of wind turbine aerodynamic characteristics, the theoretical tounOatlon or me varlaDle-speeo operation for maximum captured power and pitch-controlled methods is built. The variable-speed control technology and pitch-controlled system are detailed designed. 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.
