Titre : Detailed state of the art review for the different online/inline oil analysis techniques in context of wind turbine gearboxes Type de document : texte imprimé Auteurs : Andrew Hamilton, Auteur ; Francis Quail, Auteur Année de publication : 2012 Article en page(s) : 18 p. Note générale : Tribology Langues : Anglais (eng) Mots-clés : Condition  monitoring  Fluorescence  Fourier  transform  spectra  Gears  Infrared  spectra  Lubricating  oils  Maintenance  engineering  Photoacoustic  spectra  Sensors  Wind  power  Wind  turbines Index. décimale : 621.5 Energie pneumatique. Machinerie et outils. Réfrigération Résumé : The main driver behind developing advanced condition monitoring (CM) systems for the wind energy industry is the delivery of improved asset management regarding the operation and maintenance of the gearbox and other wind turbine components and systems. Current gearbox CM systems mainly detect faults by identifying ferrous materials, water, and air within oil by changes in certain properties such as electrical fields. In order to detect oil degradation and identify particles, more advanced devices are required to allow a better maintenance regime to be established. Current technologies available specifically for this purpose include Fourier transform infrared (FTIR) spectroscopy and ferrography. There are also several technologies that have not yet been or have been recently applied to CM problems. After reviewing the current state of the art, it is recommended that a combination of sensors would be used that analyze different characteristics of the oil. The information individually would not be highly accurate but combined it is fully expected that greater accuracy can be obtained. The technologies that are suitable in terms of cost, size, accuracy, and development are online ferrography, selective fluorescence spectroscopy, scattering measurements, FTIR, photoacoustic spectroscopy, and solid state viscometers.
