摘要
为了描述垂直轴风力机的输出特性,对垂直轴风力机运行风况、传动系统以及转速控制系统在MATLAB/SIMULINK模块中进行建模。以5 k W垂直轴风力机为例,运用双向多流管模型得到该风力机不同叶尖速比下的功率系数,并将数据导入MATLAB并运用曲线拟合工具箱得到该5 k W垂直轴风力机的风轮数学模型,从而建立SIMULINK模型。将风轮模型与其它模型组成风力机模型,给定风力机的一些运行参数,得到了可供分析的数据。通过仿真研究表明,MATLAB/SIMULINK可以较好地模拟风力机从风轮到传动系统的整体性能,为今后研究垂直轴风力机的整体性能提供参考依据。
In order to describe the output characteristics of a vertical axis wind turbine, the wind speed model, drivesystem and speed control system of a vertical-axis wind turbine are established in MATLAB/SIMULINK. Particularly, takinga 5KW vertical axis wind turbine as example, the power coefficients under the different tip speed ratio are received by usingDouble-Multiple Streamtube （DMS） model. Then the data is imported into MATLAB, and the mathematical model of the5 KW vertical axis wind turbine rotor is obtained by using the curve fitting toolbox, thus the SIMULINK model is built. Laterthe wind turbine model is formed by these above models and other models. Some operation parameters of wind turbine aregiven, and the data for analysis is received. Through the simulation study, MATLAB/SIMULINK can better simulate theoverall performance of a wind turbine from wind turbines to the drive system, which provides a reference for the futureresearch of the overall performance of vertical axis wind turbines.
