Abstract

Se presentan los resultados del estudio cuyo objetivo fueconseguir una primera aproximación a la definición de parámetros para el monitorado de la condición de generadores del tipo HSR7719-8P de grupos electrógenos HYUNDAI HIMSEN instalados en unacentral eléctrica, basada en el análisis de vibraciones por bandas espectrales.Se efectuaron mediciones en los 24grupos electrógenos instalados,registrándose las vibraciones en banda estrecha en términos de velocidadpico parapuntos seleccionados en correspondencia conlanorma ISO 8528-9. En los registros se discriminaron aquellas componentes procedentes del motor de combustión interna y se definieron cuatro bandas espectrales de alarma con carácter discreto, como punto de partida para monitorar la condición de los generadores. Se estimaron los umbrales preliminares de alarma a través del tratamiento estadístico de las amplitudes dominantes dentro de cada banda espectral. Se concluyó que los generadores en los cuales se registraron las vibraciones, exhiben una condición normal. 

Palabras claves: monitorado de condición, banda estrecha, alarma, vibraciones.

Abstract

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.

Key words: condition monitoring, narrow band measurement, alarm, generator set.
