| Abstract: | Based on the wind turbine mathematical model,the expression of the optimal blade tip speed ratio was deduced through analysis of the maximum wind power tracking conditions.The curve-fitting method was used to obtain the expression parameters of the optimal blade tip speed ratio when there were measurement errors.Then,the optimal blade tip speed ratio could be indirectly calculated.An example shows that the fitted data have high accuracy.This study provides a new curve-fitting method for calculating the optimal blade tip speed ratio of wind turbines. |
| Keywords: | wind turbines optimal blade tip speed ratio fitting method |
