Abstract(s)
A manutenção condicionada em turbinas eólicas é entendida como um conjunto de operações que garantem a funcionalidade, segurança e longevidade destes equipamentos, com uma reflexão notável para a qualidade de energia produzida, bem como para os custos relacionados com as prováveis indisponibilidades das mesmas.
As tendências atuais na utilização das turbinas eólicas na produção de energia elétrica, justificam a importância de investir em estudos contínuos sobre o princípio de funcionamento o controlo dos seus componentes, com destaque aos mais suscetíveis a falhas que conduzem a retirada do grupo gerador.
Com a realização do presente trabalho avaliaram-se diferentes estratégias utilizadas na manutenção de turbinas eólicas, tendo como foco variáveis relacionadas com a monitorização de óleos lubrificantes, análise de vibrações e a temperatura. As análises integram dois momentos chave, o antes e o depois de várias substituições de caixas multiplicadoras e dos seus componentes, geradores e rolamentos dentro do gerador, localizados no Drive End (DE) e no None Drive End (NDE). O principal objetivo do presente trabalho foi a avaliação das estratégias utilizadas na manutenção de turbinas eólicas a a sua eficiência na produção de energia elétrica.
A metodologia aplicada foi de analisar os parâmetros acima mencionados para as 38 turbinas pertencentes à empresa VentientEnergy localizadas no parque eólico da Pampilhosa da Serra, este estudo utilizou dados recolhidos durante um período de 5 anos, de 2019 até 2023. As ferramentas utilizadas para a análise e tratamento de dados foram, Renewables Management System-RMS iberwind, MATLAB e excel.
Os resultados desse estudo apontam para fortes correlações entre as curvas de potência antes e depois das intervenções de manutenção, bem como a redução de valores de vibração, contudo na variável temperatura e análises de óleos não se encontrou um padrão entre o antes e depois da substituição.
Conditioned maintenance on wind turbines is understood as a set of operations that ensure the functionality, safety, and longevity of these equipment, with a notable impact on the quality of energy produced, as well as the costs related to their potential unavailability. Current trends in the use of wind turbines for electrical energy production justify the importance of investing in continuous studies on the operating principles and control of their components, with emphasis on those most susceptible to failures that lead to the removal of the generator set. In carrying out this work, different strategies used in the maintenance of wind turbines were evaluated, focusing on variables related to the monitoring of lubricating oils, vibration analysis, and temperature. The analyses integrate two key moments, before and after several replacements of the gearbox and its components, generator bearings inside, Drive End (DE) and Non-Drive End (NDE). The main objective of the present work was to evaluate the strategies used in the maintenance of wind turbines and their efficiency in the production of electrical energy. The applied methodology was to analyze the parameters for the 38 turbines belonging to the VentientEnergy company located at the Pampilhosa da Serra wind farm. This study used data collected over a period of 5 years, from 2019 to 2023. The tools used for analysis and data processing were the Renewables Management System-RMS Iberwind, MATLAB, and Excel. The results of this study indicate strong correlations between power curves before and after maintenance interventions, as well as a reduction in vibration values. However, for the temperature variable and oil analysis, a correlation between before and after replacement was not found.
