Combined wind speed model based on real wind data

As the interest towards wind energy becomes a great concern, it´s significant to model wind speed accurately and smoothly for the simulation of wind power system in laboratory. In view of this, an improved wind speed model with 4 components has been established by Matlab/Simulink platform, which shows well performance in describing real wind characteristics of gust, gradual change wind and random noise wind. To further testify its accuracy and reliability, it´s indispensible to consider real wind conditions. Based on the wind speed data in YunNan Province of China, a comprehensive model system has been built. Compared with random noise wind speed model, the results show that the 4-component composite wind speed model can provide a more desirable modelling to simulate real situation of gust, gradual change wind and random noise wind. Therefore, combined wind speed model can be an effective and practical part in the wind power experimental platform.
