Condition monitoring and diagnostics of wind turbines — Part 2: Monitoring the drivetrain

This document specifies the implementation of a condition monitoring system for wind turbines, with particular focus on monitoring of the drivetrain. Guidance for a practical implementation of the FMSA is provided, as well as guidance for specifying best practices and minimum recommendations regarding the condition monitoring system used for failure mode detection, diagnostics and prognostics of the direct drive and geared wind turbine drivetrain, including:

a) main bearing(s);

b) gearbox, if applicable; and

c) generator (mechanical aspects).

This also includes subcomponents such as coupling and the lubrication system.

This document provides an overview of the important aspects of condition monitoring of wind turbines and makes references to other standards where in-depth information on the subjects is available.
