Analysis of the Operating History of Brazilian Power Generation Plants using Maintenance Indicators

Large power generation plants play a crucial role in meeting consumer demand and maintaining the stability of the electrical system. Different types of plants, each with their own operational characteristics, contribute to the complementarity of the electric power system. This study aims to analyze the operational history of six Brazilian plants using data provided by the National System Operator (ONS). Indicators such as Mean Time to Repair (MTTR), Mean Time to Failure (MTTF), Mean Time Between Failures (MTBF), Failure Rate, Total Downtime, and Availability will be calculated. From this analysis, it will be possible to identify which plants have the best indicators and which ones need improvements in their operation and maintenance processes. This type of study is essential to ensure the efficiency and reliability of the Brazilian electrical system, enabling the implementation of more effective preventive and corrective maintenance strategies. The main contribution of this study is to provide a better understanding of the maintenance needs of power generation plants in Brazil, enabling the formulation of policies and practices that ensure the robustness of the national electrical system.
