Condition monitoring of noise output

Published:  13 August, 2014

TWI_d009170_10_Wind_turbine_photography.jpgA joint industry project known as CMDRIVE to develop the use of a non-contact microphone array for structural health monitoring of the rotating machinery in the nacelles of wind turbines has been launched by TWI and wind turbine service provider Renewable Technical Services Ltd (RTS).

The project will first establish the feasibility of an in-situ noise capture system then develop an integral condition monitoring and active noise control kit for use onshore. The new diagnostics hardware will aim to have environmental impact in enabling noise levels of machinery to be reduced and allow the industry itself to make a dramatic reduction in the amount of downtime required for maintenance or exploratory investigation if failure arises.
