Avaliação de desempenho da estratégia de representação laboratorial de turbinas eólicas utilizando motores de indução controlados

Abstract

Currently, it is observed an increasing energy demand worldwide. Thus, it is great the search for a more sustainable energy model that is able to meet all the need. In this context, there come the renewable energy sources which present with low environmental impact when compared to other options. Among renewable sources, the wind energy stands out as one of the most promising, which implies an increasing interest in studies for the development of this technology that is still coming up with limitations due to the complexity of the strategies employed. In particular, although the recognition of a large number of computational work aimed at the representation of wind complex, there must be pointed that the resources aimed to laboratory studies, which greatly complement the training and research, are not easily found. In light of these facts and seeking the establishment of a strategy focused on the experimental representation of small-scale wind turbines, this work presents a proposal to use the inverter controlled induction motor as an alternative to replace the wind turbine. Under this strategy, this dissertation advances towards performing simulations to obtain information pertinent to mechanical and electrical quantities in various parts of the conceived structure. Finally, a comparative analysis is made with the technique that adopts controlled dc motor for the same goal.
