Open-End Winding Induction Machine Fed by a Dual-Output Indirect Matrix Converter
(2016)
Open-ended winding induction machines fed from standard two-level voltage source inverters (VSIs) provide an attractive arrangement for ac drives. An alternative approach is to use a dual-output indirect matrix converter ...
Rastreamento do ponto de máxima potência de turbinas magnus acionando geradores elétricos
(Universidade Federal de Santa MariaBREngenharia ElétricaUFSMPrograma de Pós-Graduação em Engenharia Elétrica, 2014-01-24)
The constant human need for electricity, as well as the increasing demand for energy causes the use of finite sources, as oil and coal. The search for alternative energy sources as wind harvesting is the motivation for ...
Estudo e desenvolvimento de um aplicativo em ambiente Simulink/Matlab para simulação de uma turbina eólica
(Universidade Tecnológica Federal do ParanáPato Branco, 2013-03-01)
This work studies regarding the process of energy conversion systems for wind power generation. Initially, we present an analysis of how today takes the use of wind energy in Brazil and worldwide, considering that the use ...
Initialization of the DFIG Machine for Electromagnetic Transients Calculation
(Institute of Electrical and Electronics Engineers, 2018-02)
There is currently a strong trend in the world toward the use of power generation from renewable resources. This poses new challenges with respect to the modeling of electrical generators connected to power electronics ...
Diagnóstico de desequilíbrio de massa para rotores de aerogeradores utilizando máquina de vetores de suporte
(Universidade Federal de Santa MariaBrasilEngenharia ElétricaUFSMPrograma de Pós-Graduação em Engenharia ElétricaCentro de Tecnologia, 2021-02-26)
Condition monitoring systems (CMS) are essential to reduce costs in the wind
energy sector. This paper proposes a method based on Support Vector Machine (SVM)
to detect rotor mass imbalance for a multi-class problem, ...
Emulação dos regimes permanente e transitório das turbinas de eixo horizontal incluindo o modelo estático da turbina Magnus
(Universidade Federal de Santa MariaBREngenharia ElétricaUFSMPrograma de Pós-Graduação em Engenharia Elétrica, 2014-01-24)
The lodgment of wind sites is in a visible growing demand not only in Brazil, but all over the
world. The wind energy, even though consolidated, still hosts many scientific researches and
industrial development in several ...
Inverter-fed linear asynchronous machine
(1998-12-01)
The behaviors of an arc-shaped stator induction machine (the sector-motor) and a disc-secondary linear induction motor are analyzed in this work for different values of the frequency. Variable frequency is produced by a ...
