DETERMINING A DEFLECTION OF A ROTOR BLADE OF A WIND TURBINE |
| 摘要 |
A method is provided for determining a deflection of a rotor blade of a wind turbine including the following steps: fixing at least one electrical conductor loop via fixing points to at least one surface of the rotor blade, wherein the at least one electrical conductor loop is arranged such that due to the deflection of the rotor blade an extension of the at least one conductor loop is forced between at least two of the fixing points, the extended electrical conductor loop keeps closed if the deflection of the rotor blade is below the defined threshold, the extended conductor loop opens if the deflection of the rotor blade is beyond the defined threshold. Further an arrangement, a sensor, a rotor blade and a wind turbine are also provided. |

1. A method for determining a deflection of a rotor blade of a wind turbine comprising:
fixing at least one electrical conductor loop via a plurality of fixing points to at least one surface of the rotor blade, wherein the at least one electrical conductor loop is arranged such that: due to the deflection of the rotor blade, an extension of the at least one conductor loop is forced between at least two of the plurality of fixing points, the extended electrical conductor loop keeps closed if the deflection of the rotor blade is below a defined threshold, and the extended conductor loop opens if the deflection of the rotor blade is beyond the defined threshold. |
