METHODS AND SYSTEMS FOR DETECTING WIND TURBINE ROTOR BLADE DAMAGE |
| 摘要 |
Methods and systems for detecting rotor blade damage in a wind turbine are provided herein. A monitoring system includes a filter module and a damage determination module. The filter module is configured to determine an amplitude of a 1P frequency component of at least one operating condition of the wind turbine. The damage determination module is configured to compare the determined 1P frequency component amplitude to a threshold 1P frequency component amplitude. |
