Resumen
Desde hace algunos años se introdujo en el país el concepto de generación distribuida de energía eléctrica utilizando grupos electrógenos, estos equipos requieren de un análisis vibracional continuo para detectar la aparición temprana de fallas en su funcionamiento y fallas en las condiciones técnicas que repercuten en su mal funcionamiento, deterioro o paralización, con el consiguiente perjuicio para la
generación. En el trabajo se realiza una revisión bibliográfica con el objetivo de resumir y mostrar los aspectos principales de cómo realizar el diagnóstico técnico a los grupos electrógenos de generación distribuida, así como los principales ensayos y modelos matemáticos utilizados en su desarrollo, con el fin del diagnosticar las vibraciones y el aislamiento de vibraciones en grupos electrógenos. En la actualidad, existe la necesidad en el país de realizar estudios para determinar los niveles de
vibraciones en los grupos electrógenos con relación a los niveles admitidos por sus fabricantes, razón por la cual, el Departamento de Ingeniería Mecánica de la Universidad Central “Marta Abreu” de las Villas, ve la necesidad de efectuar un análisis y determinación de tendencias vibraciones en estos equipos y establecer el diagnóstico y el aislamiento de vibraciones en grupos electrógenos. La
determinación de tendencias vibracionales en los grupos electrógenos, permitirá disponer de un conocimiento completo de los niveles reales de vibración que tienen estos equipos y en base a ello, recomendar las acciones correctivas necesarias.
For some years it was introduced in the country the concept of distributed generation of electric power using by generating sets, these teams require of an analysis continuous of vibrations to detect the early appearance of flaws in their operation and flaws under the technical conditions that rebound in their bad operation, deterioration or stop, with the rising damage for the generation. At work from now on a bibliographic revision for the sake of summing up and showing the major issues comes true of how accomplishing the technical diagnosis to the generating sets of generation distributed as well as the principal essays and mathematical models more used in your development, with end of establishing a proposed methodology for the diagnosis and the isolation of vibrations in generating sets. Generation's concept distributed of electric power using generating sets was introduced at the country for some years; these teams call for a vibrational continuous analysis to detect the premature appearing of faults in their functioning and you fail in the technical conditions that have influence upon your impairment of function, deterioration or paralyzation, with the resulting damage for the generation. As of the present moment, the need at the country of accomplishing studies to determine the levels of vibrations in the generating sets with respect to the levels admitted by his manufacturers, reason exists for which, the Department of Mechanical Engineering of the Central University Marta Abreu de las Villas, sees the need to make an analysis and determination of vibrational tendencies in these teams and to propose a methodology for the diagnosis and the isolation of vibrations in generating sets. The determination of vibrational tendencies in the generating sets, it will allow having a complete knowledge of the real levels of vibration that these equipment‟s have and on the basis of it, recommending the corrective necessary actions.
