A Review on Failure Modes of Wind Turbine Components

Fatigue Life of Wind Turbine Structural Components

Modern mega watt class wind turbines are exposed to high and complex loads. At the same time the aim is to realize light weight and optimized structures. Compared to other industries the design lifetime of a wind turbine is very long. Applying simulation tools for the predictions of fatigue life is therefore essential. This paper presents the approaches for fatigue anaylses used in the wind ind...

Dynamic Analysis of Wind Turbine Gearbox Components

Abstract: This paper studies the dynamic response of a wind turbine gearbox under different excitation conditions. The proposed 4 degree-of-freedom (DOF) dynamic model takes into account the key factors such as the time-varying mesh stiffness, bearing stiffness, damping, static transmission error and gear backlash. Both the external excitation due to wind and the internal excitation due to the ...

Effects of gain-scheduling methods in a classical wind turbine controller on wind turbine aeroservoelastic modes and loads

Wind Turbine Failure Risk Assessment Model Based on DBN

* Energy & Power Engineering School, North China Electric Power University China, Beijing, ([email protected]) ** Energy & Power Engineering School, North China Electric Power University China, Beijing, ([email protected]) Abstract As wind turbine is mainly composed of two strongly coordinated mechanisms, the transmission mechanism and the energy conversion, fault propagation characteristics ...

Aerodynamics of wind turbine wakes Literature review

This report reviews the available literature on the aerodynamics of wind turbines and wind farms. Firstly, two introductory chapters are devoted to the physics of the flow around a wind turbine and the existing engineering models for blade and wake aerodynamics. The focus of this work is however on the numerical modeling of wakes. The difficulties in solving the Navier-Stokes equations are disc...
