Reliability Based Maintenance Planning of Wind Turbine Using Bond Graph

Wind power generation is an effective form of clean, renewable energy which operates both on land and offshore. The primary means of converting wind to power is by wind turbines. The issue with wind turbines is high uncertainty of operating environment resulting in low life cycle reliability. Frequent breakdown failures resulting in reactive maintenance is costly which results in downtime and l...

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 ...

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...

Fatigue reliability analysis of jacket-type offshore wind turbine considering inspection and repair

In this paper prediction of the fatigue reliability of a fixed jacket offshore wind turbine designed for a North Sea site in a water depth of 70 m is performed. The longterm statistical distribution of stress ranges of tubular joints is obtained by combination of time domain simulation for representative sea states. The load histories are normalised to ensure that fatigue design criteria based ...

Reliability-Based Design Optimization of Wind Turbine Blades for Fatigue Life under Wind Load Uncertainty

1. Abstract Conventional wind turbine blades have been designed using fatigue life predictions based on a fixed wind load distribution that does not fully capture uncertainty of the wind load. This could result in early fatigue failure of blades and eventually increase the maintenance cost of wind turbines. To produce reliable as well as economical wind turbine blades, this paper studies reliab...
