Model-OA wind turbine generator: failure modes and effects analysis
William E. Klein, V.R. Lali · 2002
The results are presented of a failure modes and effects analysis (FMEA) conducted for wind turbine-generators. The FMEA was performed for the functional modes of each system, subsystem, or component. The single-point failures were eliminated for most of the systems. The blade system was the only exception. The qualitative probability of a blade separating was estimated at Level D-remote. Many changes were made to the hardware as a result of this analysis. The most significant change was the addition of the safety system. Operational experience and need to improve machine availability have resulted in subsequent changes to the various systems, which are also reflected in this FMEA.>
