PALOMINO-MARIN, Evelio; CABRERA-GOMEZ, Jesús  e  CEPERO-AGUILERA, Yanexy. Condition monitoring in engine generator sets based on vibration analysis by spectral bands. Ingeniería Mecánica [online]. 2018, vol.21, n.3, pp. 130-137. ISSN 1815-5944.

Based on the vibration analysis by spectral alarm bands, it is shown a first approximation of condition monitoring for generators HSR7719-8P of HYUNDAI HIMSEN engine generator sets atreal power plant. Measurements were made on 24 engine generator sets, recording narrow band peak vibrations at selected points according toISO 8528-9. Registered frequency components from the engine were not taken into account and four discrete spectral alarm bands were defined, as a starting point to condition monitoring of such generators. Preliminary alarm thresholds were estimated using statistical treatment of the dominant amplitudes within each spectral band. It was concluded that those generators in which the vibrations were recorded exhibit a normal condition.
