Concept

The first solution that uses airborne emissions to assess the integrity of wind turbine drivetrains

car-network-electric_02

The ACMwind solution is a bespoke, non‐intrusive, acoustic‐analysis CM system, which utilises an acoustic sensor array to detect faults in drivetrain components at an early stage. The developed non‐contact sensor array consists of a group of acoustic pressure sensors arranged in a manner which allow for easy installation and set‐up. This acoustic array is capable of detecting the sound-borne emissions from the different components of the drivetrain including main bearing, gearbox and generator. Vibrations from all the rotating components within the nacelle are monitored through the airborne noise.

Additionally, the signal processing algorithm can differentiate the origin of the sound, and thus prescribe the defect to the faulty piece of machinery (gearbox, bearings and so on). The designed software will then automatically recognise the structural health signature of each monitored component from analysis of the frequency and time dependence of the acoustic array responses. The software also allows for both noise and vibration reduction within the turbine components. The complete system therefore provides continuous, non‐intrusive, health monitoring of the wind turbine drive‐train, combined with active noise cancellation algorithms. The distinct, quantitative history of the structural integrity of the machine components will allow operators to estimate the time left until failure.
