Reliable wind energy: Improving the reputation of wind energy

Renewable energy systems are a vital way of guaranteeing sustainable energy for the future, and wind turbines are regarded as one of the most promising technologies. However the reliability of wind turbines needs to be improved as they rarely reach the desired lifetime of 20 years without mechanical failure of the major drivetrain components. The drivetrain of a wind turbine is composed of the gearbox, the generator, and the necessary components that a turbine needs to produce electricity. Mechanical failure of any of these components can be expensive to repair and lead to downtimes of several days, or even weeks, resulting in significant cost in terms of lost energy production. These issues are likely to become worse as wind turbines become larger and offshore installations become more common, i.e. with the associated access and safety issues. The principal problem is that NMIs do not currently offer calibrated measuring standards for drivetrain components because they are so large, and even measurement processes for industrial large component measurements are insufficient. This project therefore developed measurement techniques for drivetrain components and traceable standards that were appropriate for large parts. These were then put into practice by manufacturers in order to have the potential to increase the reliability of drivetrain components.
