Techniques and apparatuses for wind turbine component (120,125,160,175) fatigue load measurement and assessment are disclosed. In one embodiment the component is a tower (190) in which fore-aft and side-to-side signals from a two-axis accelerometer attached to a bedplate (172) of a wind turbine are used to measure tower fatigue loads. A yaw axis azimuth position signal can also be used for tower fatigue load measurement and assessment. |
