摘要
文章针对风力机的强非线性设计了模糊PID电动变桨距控制器,以此实现风电机组在不同风速段下的功率控制策略,即在低于额定风速阶段,系统能跟踪最大功率点;在高于额定风速阶段,通过变桨距控制器调节桨距角,将功率限制在额定功率附近。理论分析和仿真结果表明,该电动变桨距控制系统的桨距角控制策略达到了设计的预期目标,为其在实际风场中的应用奠定了基础。
In view of the strong nonlinearity of wind turbine,a fuzzy PID electric pitch controller is designed to realize the power control with different wind speed interval.The control system can track the maximum power point（MPP） below the rated wind speed;when wind speed is above the rated value,the system can keep the rated output power through the adjustment of the pitch angle.Both theoretical analysis and simulation results indicate that the pitch control strategy of the electric pitch control system reaches its goal and establishes a foundation for its application in the wind farm.
