ABSTRACT
The article discusses the importance of monitoring the oscillation of wind turbine blades to keep them turning. Rotor blades are considered the most accident sensitive parts of a wind turbine. Among the most common problems with wind turbine blades are excessive load, lightning damage and ice formation. The traditional method of monitoring blades includes using dual anemometers (one heated) or to monitor the ambient conditions.
