Commercial grade wind turbines generally have a target design life of 20 years. This goal is frequently elusive with key components like the gearbox often showing much shorter life in service.
Continuous condition monitoring and motion control are technologies which are beginning to improve the reliability of wind turbines. Condition monitoring can reduce downtime by advance warning of the problem and in some cases making simpler repairs as opposed to full replacement.
There are many ways for advanced monitoring and control technologies to improve the reliability of wind turbines. For more details, see the article at:
