ABSTRACT:
Condition-based monitoring functionality using sensors that monitor wind turbine component movement. A main shaft flange displacement sensor system can be used to provide signals used to perform fatigue assessment of the wind turbine rotor blades as well as drive train components. Output signals from the main shaft flange displacement sensor system are used to perform fatigue assessment, failure trending, diagnostic analysis, etc.
