Gestão da manutenção de sistemas eletromecânicos em usinas hidrelétricas: revisão bibliográfica sobre eficiência, confiabilidade e sustentabilidade.

Abstract

Maintenance management in electromechanical systems of hydropower plants is essential to ensure high levels of reliability, availability, and operational efficiency. This study presents a systematic literature review with a qualitative approach aimed at analyzing the main practices, methodologies, and technologies applied to industrial maintenance in the hydropower sector. The research was carried out through scientific databases and technical documents published between 2015 and 2025. The findings indicate a transition from corrective approaches to predictive and condition-based strategies, highlighting continuous monitoring techniques, vibration analysis, thermography, and digital technologies. It is concluded that the integration of predictive maintenance, asset management, and digital technologies represents a strategic factor for improving reliability and operational sustainability.
