Research on Wind Speed Model of Wind Power Generation System Based on MATLAB

风能的随机性和间歇性,会导致风电过程的不稳定。分别介绍了基于四分量组合模型、威布尔分布模型、ARMA模型生成风速时间序列的方法。为研究这三种不同的方法,使用MATLAB工具对给定参数下的数学模型进行建模仿真,通过与实测风速数据对比,验证所建模型的有效性。对这三种时间序列进行功率谱分析,阐述各种方法的优缺点及适用情况,为实验室进行风力发电系统的模拟研究提供理论依据和重要支撑。

This paper describes three methods for generating wind speed time series combination of four-component modei,Weibult distribution modeI,ARMA model.In order to study these three different methods,MATLAB is used to given to model and simulate the given parameters of the mathematical models.Validate the models by comparing the simulation results with the measured wind speed data.It analysises these wind speed time series use power spectral density technology.
