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 ...
Contribuições ao projeto de sistemas eólicos de efeito magnus com rastreamento da máxima potência
(Universidade Federal de Santa MariaBrasilEngenharia ElétricaUFSMPrograma de Pós-Graduação em Engenharia ElétricaCentro de Tecnologia, 2016-08-26)
This work deals with an unconventional wind energy conversion system, in which the wind turbine has rotating cylinders rather than traditional blades. These cylinders can be driven by a brushless DC motor. The turbine ...
