1. Analysis of flicker level on the integration of fixed speed wind generators using multidiscipline models / Análise dos níveis de flicker na integração de geradores eólicos de velocidade fixa em redes de distribuição de energia elétrica utilizando modelos multidisciplinares
The discussions about the environmental issues and the need for renewable sources of energy, with low environmental impacts, mainly about CO 2 emission, have encouraged the Wind Energy expansion. The support for wind energy in the last decades enabled the improvement of the technology and a representative share in the electrical systems of some countries. Th

2. Contribuição ao estudo de aerogeradores de velocidade e passo variáveis com gerador duplamente alimentado e sistema de controle difuso / Contribution to the study of fuzzy control applied to variable-speed variable-pitch wind generators with double-fed induction generator
The efficient capture of aeolic-energy occurs by means of three blades turbines with adjustable pitch-angle and angular-speed. The pitch-angle adjustment is utilized to limit the aeolic-energy capture when occur very strong winds and, the angular speed adjustment is utilized to maximize the capture of kinetic energy of weak winds. In this mode of operation t

3. Uma contribuição à modelagem de complexos eólicos contendo geradores especiais para atenuação das componentes harmônicas
Most of the wind energy conversion systems (WECS) currently in operation in the world use asynchronous generators in the transformation of wind energy into electricity energy. In Brazil, although it is recognized that the parcel of wind farms is still very reduced, it is evidenced that the principle of the employed generation is mainly synchronous. Within th

4. Modelagem e análise de desempenho dinâmico de complexos elétricos contendo centrais eólicas dotadas de geradores síncronos / Modeling and dynamic performance analysis of electric power systems containing wind installations equipped with synchronous generators
New generation resources, with low implantation and operation costs and that provoke the minimum possible impact to the environment, are undoubtedly focuses of attention to all the segments of the society. From this common sense, the alternative or renewable sources of energy, and particularly the wind, have certainly had a significant penetration in the com
