摘　　要：基于差动调速控制功率方法的新型风电机组的特征在于利用差动轮系和调速电机组成可变速比的传动系统,末端采用同步发电机不经变频器即并入电网。但针对该类机组有效的功率控制方法尚缺乏研究,对其设计理论体系构建、工程应用实践等方面缺乏支撑。鉴于此,文章结合风能利用率C_(p)与桨距角β和叶尖速比λ的关系,研究了低于额定风速和高于额定风速两种工况下的差动调速功率控制方法;运用Simulink软件搭建了1.5 MW的新型风电机组模型,以多段阶跃风速作为输入,采用所述控制方法对机组运行功率进行实时调节。将机组各关键参数的仿真结果与理论值进行比较,验证了该新型风电机组差动调速功率控制方法的有效性。The differential gear train and speed regulating motor constitute the variable ratio transmission for grid-connected wind turbine based on differential speed regulation. The synchronous generator in the system can accessing the power grid without frequency converter. However, there is still a lack of research on effective power control methods for such wind turbine,and there is a lack of support for the construction of design theory system and engineering application practice. The power control method is studied under the different wind speed which is lower or higher than rated wind speed with using the relational expression of utilization rate of wind energy C_(p), pitch angle β and the tip speed ratio λ. The Simulink software is used to build the 1 500 kW wind turbine model with differential speed regulation. Some different wind speed is made as input. The power control method is used to adjust the simulation running power of the wind turbine in real time. The feasibility of power control method for grid-connected wind turbine based on differential speed regulation is verified by the comparison between the simulation results and the theoretical value of the key parameters.
