直驱永磁风电机组输入输出特性拟合

The Input/output Characteristic Fitting of Direct-Drive Permanent Magnet Wind Generator

运用曲线拟合方法,可拟合直驱永磁同步风电机组的输入输出特性.研究发现,理想条件下功率-风速的数值拟合精度高,而实际测量值拟合精度差,在高风速运行条件下,输入功率-机组转速和机组转速-输出功率的数值拟合精度高,而低风速运行条件下,拟合精度低.

The input/output characteristics of direct-drive permanent magnet synchronous generator can be fitted by adopting the curve fitting method.The study indicates that in ideal circumstances the numerical fitting of power and wind speed is highly precise,whereas actually it is insufficiently precise.Furthermore,in high wind speed conditions,input power and rotor speed curve and rotor and output curve fit with high precision,while in low wind speed conditions,the fitting is less precise.
