Drivetrain Reliability Collaborative Workshop

This workshop welcomes researchers from across the wind turbine industry to discuss the latest gearbox modeling tools, designs, and testing procedures to improve gearbox reliability and an overall reduction in the levelized cost of wind energy.

Premature gearbox failures have a significant impact on the cost of wind farm operations. In 2007, NREL initiated the Drivetrain Reliability Collaborative. The project combines analysis, field research, dynamometer research, condition monitoring, and the development and population of a gearbox failure database in a multi-pronged approach to determine why many wind turbine gearboxes do not achieve their expected design life—the time period that manufacturers expect them to last.
