| 摘要 |
The present invention relates to a wind-velocity-field measurement system for use in a wind turbine having a rotor with two or more blades, comprising at least one sensor-signal obtained by measuring a physical quantity on at least one of the blades, the physical quantity being indicative of at least one wind-velocity-field characteristic; a table (140, 142, 144) build for a plurality of wind conditions by associating values characterizing the at least one sensor-signal with values of the at least one wind-velocity-field characteristic, and; searching means (150, 152, 154) for determining from the table a value of the at least one wind-velocity-field characteristic for a current wind condition given values characterizing the at least one sensor-signal. |
