基于运行数据的风力机建模与验证

method for the wind turbine modeling is presented based on operating data. According to measured operating data and statistical methods, the measured power curve of wind turbine is obtained and used to set up the mapping relationship between tip-speed ratio and wind power coefficient. For fixed speed wind turbines, through using look-up table to establish wind turbine model, the wind generation system is obtained. For variable speed wind turbine, modules of maximum power tracking and wind power coefficient look-up table are corrected by using power curve and the measured data. Compared with the measured data, the simulation results show that the model based on proposed method has higher accuracy and engineering value.
