Fault Detection of Drive Trains in 10 MW Offshore Wind Turbines using Non-Traditional Methods

One of the world’s biggest concerns is global warming, a solution to this can be wind energy. Offshore wind energy has advantages over onshore wind energy, however, the levelized cost of energy is higher. The maintenance costs are a major cost contributor. To lower these costs, research is performed on faults and its detection. Currently, little...

Wind turbine technology battles: Gearbox versus direct drive - opening up the black box of technology characteristics

This paper studies the battle between two types of wind turbines, the gearbox wind turbine and the direct drive wind turbine. Applicable determinants that affect technological dominance for the wind turbine drive trains case are identified. By applying the Best-Worst Method, the relative importance to the determinants to understand which of...

Limiting mechanisms for the torque density of wind turbine drivetrains

As wind turbines continue to increase in size, so do the loads acting on the drivetrain.<br/>To handle the higher loads the mass of the drivetrain needs to increase. A better understanding<br/>of this mass increase can result in lighter drivetrain design and provide<br/>an insight which drivetrain design has the lowest mass potential for large...

Evaluation of gearbox and direct drive wind turbines: An application of the technology dominance theory combined with the Best-Worst-Method to assess the effect of factors for technology dominance on the technology dominance process of wind turbines

Power generation is at the forefront of a transition from fossil fuel to renewable energy sources (RES). Wind energy is a promising technology with rapid developments and the installed base of wind turbines is continuously increasing. Currently, the majority of the installed wind turbines can be categorised under the direct drive wind turbine...
