The prime objective of the work is to extract information from existing data so that the reliability of large wind turbines can be predicted, particularly when installed offshore in the future. The article uses data collected from the Windstats survey to analyse the reliability of wind turbine ...
for reliability analysis of the wind turbine tower and blades are outlined for three different limit states: • Ultimate loading – Standstill position • Ultimate loading – Operational condition • Fatigue loading Finally, a numerical example is presented where ...
Failure mode and effects analysis (FMEA) has been proven to be an effective methodology to improve system design reliability. However, the standard approach reveals some weaknesses when applied to wind turbine systems. The conventional criticality assessment method has been criticized as having many lim...

Recent analysis of European onshore wind turbine reliability data has shown that whilst wind turbine mechanical subassemblies tend to have relatively low failure rates but long downtimes, electrical and electronic subassemblies have relatively high failure rates and short downtimes. For onshore wind ...
Numerical analysis of the NREL 5 MW wind turbine supported by monopile, tripod and jacket substructures shows that the uncertainties of soil properties affect the reliability index more significantly for the monopile-supported OWTs while the reliability index is not so sensitive to the material ...
A seismic reliability analysis of the jacket-type support structure for an offshore wind turbine was performed. When defining the limit state function using the dynamic response of the support structure, numerous dynamic calculations should be performedin an approach like the FORM (first-order reliabi...
The errors between the calculating results and metric results have been compared, and the vibration shapes of blade have been analyzed. All the results provide the diagnostic theories for fatigue prediction, resonance removal and reliability analysis for wind turbine's blades design. 展开 ...
