WIND TURBINE BLADE CONTROL METHOD |
| 摘要 |
A control method for a wind turbine, in particular for a wind turbine blade is described. The control method makes use of the blade mode shapes, or natural vibration shapes, of the blade to detect the excitement level of the blade natural vibrations, and controls active lift devices on the blade in an effort to reduce the excitement levels, to reduce loading in the blade and the overall wind turbine structure. There is also provided a method of designing a wind turbine blade for use in such a method. |

1. A method of controlling a wind turbine blade during operation of a wind turbine to reduce root moments of the blade, the blade having a tip end and a root end, the method comprising the steps of:
identifying an excited mode shape of the wind turbine blade; and adjusting at least one active lift device provided on said blade to reduce a modal vibration of said blade during operation of said wind turbine, wherein said step of adjusting is based on said excited mode shape. |
