Avaliação de desempenho de turbina eólica conectada a rede básica: por meio do histórico de operação

Abstract

Wind energy is a sustainable alternative energy source experiencing significant global growth, driven by supportive policies and falling costs. The international landscape is led by countries such as China, the USA, and Germany. Brazil ranks sixth in onshore installed capacity, contributing 12.5% to the national energy matrix. Despite these advances, the operating cost, when compared to other energy sources, remains high, mainly due to the complex configuration of wind turbines (WTs), with various systems that can fail. These failures cause downtime, which implies generation losses. This research analyzes the operational performance of a WT connected to the main grid, through factors that impact its performance, such as failure rate, mean repair time, and availability. The results presented provide an overview of operations, revealing the systems with the highest failure rates and mean repair time and their respective impacts on availability, aiming to contribute to the economic competitiveness of wind energy in Brazil, minimizing costs and improving maintenance practices.
