Function
Condition monitoring systems provide additional health checking and failure prediction capability.
Who supplies them
Brüel & Kjær Vibro, Gram & Juhl, SecondWind and SKF.
Key facts
Condition monitoring systems frequently make decisions about individual components (such as the gearbox) via sensors measuring parameters for that component. They also use a range of sensor and controller outputs and make holistic decisions about all drive train components.
Condition monitoring systems on the rotor [T.2] are able to assess control behaviour as well as blade health.
Turbine and condition monitoring systems send data to cloud-based databases to facilitate analysis over a wind farm and a larger number of turbines. Results of the analysis can lead to changes in control reducing loads on a failing component. Better understanding of the condition of the turbine drive train can lead to increased power output under some conditions where the fatigue life of the turbine allows.
