Ferramenta para priorização do plano de manutenção de ativos da rede elétrica da Universidade Federal do Ceará

Abstract

Managing asset maintenance is critical to ensuring the physical integrity of equipment, reducing maintenance costs and ensuring system reliability. Among the reliability-centered maintenance, total productive maintenance and risk-based maintenance methodologies, this paper proposes the use of performance and risk indicators to calculate the priority of maintaining the Pici Campus power grid assets. These indicators were obtained from the web platform database analysis developed by the Energy Conservation Coordination (CCE) called SICEM (Equipment and Maintenance Control System). To compute the proper intervention priority, modifications were made to the database and platform access screens. In the database, tables were added to store the results of number of occurrences, date since last maintenance and equipment type. In the access screens, modifications were made to the code to display the priority result, obtained by simulating equipment failure occurrences. Finally, it can be concluded that the developed tool has the potential to assist in the elaboration of an adequate maintenance plan for the university's electrical network equipment, and may also be used to monitor the maintenance of other assets, such as equipment for refrigeration, elevators and fire extinguishers. It can also be concluded that the tools used to develop the platform, which are all free software, proved to be efficient and appropriate for the proposed application type.
