WIND TURBINE DEVICE, ABNORMALITY DETECTION DEVICE FOR WIND TURBINE DEVICE, AND ABNORMALITY DETECTION METHOD FOR WIND TURBINE DEVICE

摘要

The present invention addresses the problem of providing a wind turbine device equipped with a blade deformation measurement means that is excellent in terms of ease of installation and reliability and is capable of performing measurement with high precision. This wind turbine device is used for wind power generation, and has blades serving as rotary wings, a rotor that supports the blades, an electrical generator that is connected to the rotor, a nacelle that covers the rotor, and a tower that supports the nacelle. A means for detecting passing of the blades is disposed at least at one position on the tower.
