| Abstract: | 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. |
