| 摘要 |
The invention relates to a method to improve the optical visibility of a wind farm (WF). Warning lights are arranged and prepared for warning purposes of the wind farm. These warning lights are rotated by the rotors of a first wind turbine and of at least a second wind turbine of the wind farm. The wind speed (WS) of the incoming wind at the wind farm (WF) is measured. The wind speed (WS) is compared with a predefined wind speed. The first wind turbine (WT1) of the wind farm (WF) is turned from operational mode into idle mode if the measured wind speed (WS) is below the predefined wind speed. The rotor angle (RA1) of the first wind turbine (WT1), which is in idle mode, is saved as first rotor angle (RA1). The first rotor angle (RA1) is communicated to the at least second wind turbine (WT2) of the wind farm (WF), which is in idle mode. The rotor angle (RA1) of the second wind turbine (WT2) is adjusted to the first rotor angle (RA1), and is kept by the second wind turbine (WT2), which is in idle mode. |
