| 摘 要： | 通过机理建模法对变速恒频风力发电机组进行建模,建立了其风速、风轮气动、传动系统以及发电机的数学模型,在Matlab/Simulink环境中搭建了各个环节的模型,并针对低于额定风速时的转速控制和高于额定风速时的功率控制,采用PID控制方法对所构建的模型进行仿真控制,实现低风速和高风速时的控制目标,仿真结果验证了所构建模型的正确性和可行性.

| Abstract: | The mechanism modeling method is used to build a variable speed-constant frequency wind turbine model,and establish the mathematical model of wind speed,aerodynamic wind turbines,transmission system and the generator.All links of the model are built in the Matlab/Simulink environment.For speed control of below the rated wind speed and power control of above the rated wind speed,the PID control is used to simulate the control system for the control target of low wind speed and high wind speed respectively,and the correctness and feasibility of the model is verified by the simulation results. |
