Correlação entre pressão de óleo e perda de potência ativa em aerogeradores de eixo horizontal: uma análise exploratória dos dados do sistema de controle de pás

Abstract

Wind energy has been consolidating itself as a rapidly growing energy source, mainly due to concerns about environmental conditions, which has driven significant investments in the sector. In this context, to offer competitive prices, reducing wind turbine maintenance costs and increasing efficiency become essential. This work, therefore, investigates the correlation between the decrease in effective power and oil pressure in the blade control system in horizontal axis wind turbines, aiming to optimize predictive maintenance and improve operation and maintenance strategies in the wind sector. The research uses data segregation and stratification, correlation analysis with Pearson's Correlation Coefficient and scatterplots to identify whether oil pressure can serve as an early indicator of power loss and future failures. The temporal analysis of the correlation in different periods of wind turbine operation will allow observing the relationship between variables at different times and identifying the general behavior of the wind turbine in different oil pressure ranges. It is expected that the research will contribute to the literature on the topic, providing alternatives to increase the reliability and efficiency of wind energy generation
