Optimización del plan de mantenimiento mecánico para el mejoramiento de la disponibilidad del Sistema Oleo Hidráulico en las unidades de generación Fase AB en la Central Hidroeléctrica Paute Molino.

Abstract

The high demand for electrical energy in the country, requires maintaining the permanent availability of all the generation units of the Paute Molino Hydroelectric Power Plant. There are too many preventive interventions that cause unavailability of the generation units, this project proposed an improvement in the optimization of the mechanical maintenance plan for the improvement of the availability of the Eolic Hydraulic System in the generation units of the Phase AB, based on its history, compilation of information from the manufacturer’s manuals, equipment failures, incidents and maintenance actions, also for which maintenance management audit strategies, Pareto diagram and predictive maintenance techniques were used. For the information that served for this analysis, the results of reports and technical reports of tests performed on the assets of the present study were considered. The audit findings determined weaknesses and the results obtained were aligned to the general objective of optimization of the Mechanical Maintenance plan and allowed the increase of the availability. It concluded with the approach of reducing the time in the execution of the preventive maintenance, elimination of bimonthly maintenance and improvement of the plan of predictive maintenance and online monitoring of the condition of the equipment. It is recommended to implement the proposal.
