  • (PDF) Integrated condition monitoring scheme for

    Blade pitch bearings of large scale wind turbines control the individual blades in order to maximise power generation at low wind speeds and to prevent turbine damages under high winds. The reliability of blade pitch bearings is of critical importance to operation and energy production, especially for offshore wind turbines as any blade pitch bearing failures and replacements can be extremely costly.
