Detecção de falhas em motores de indução trifásico utilizando o método off-line avaliando a resistência estatórica
(Universidade Tecnológica Federal do ParanáCornelio ProcopioBrasilEngenharia ElétricaUTFPR, 2015-06-08)
Short circuits in the stator windings are considered as one of the major failures that occur in a three-phase induction motor (MIT), influenced by the quality of the insulation between the windings and between the phases ...
Imageamento térmico do estator de geradores de alta potência empregando sensores óticos distribuídos
(Universidade Tecnológica Federal do ParanáCuritibaBrasilPrograma de Pós-Graduação em Engenharia Elétrica e Informática IndustrialUTFPR, 2017-03-17)
This work presents a new method of thermal imaging for stator of high power generators, using distributed optical sensors based on Raman scattering, which can identify areas with relatively high temperatures in any part ...
Comportamento dos geradores de indução duplamente alimentados em turbinas eólicas de 1,5MW
(Universidade Tecnológica Federal do ParanáCuritibaDepartamento Acadêmico de Eletrotécnica, 2013-09-11)
Among the different ways to generate wind energy, one is the use of an induction machine with a wound rotor, where it is doubly-fed by the electrical system, being fed directly in the stator and in the rotor through ...
Hinf controller design for a variable wind speed turbine
(2008-10-10)
Abstract: This paper gives a description of a wind
generator system composed by a doubly fed induction
generator (DFIG), its dynamic model and each one of its
subsystems. Also, the control logic that regulates the
active ...
Diseño de experimentos para modelar las faltas de mayor incidencia en el estator de los motores trifásicos de inducción.
(Instituto Tecnológico de Costa Rica, 2012)
This paper's main objective is to design experiments to model
higher incidence of faults in the stator of the three-phase induction motors, which are
propose four experiments, the data obtained allow to know and ...
Improved Efficiency Optimization Control for Brushless Doubly Fed Induction Generator-DC System by Regulating Stator Frequency
(2023-03-01)
Taking into account the relatively low efficiency of brushless doubly fed induction generator (BDFIG) at present, the efficiency optimization is important to promote the industrial application of BDFIGs. The power winding ...
Rotor Demagnetization Effects on Permanent Magnet Synchronous Machines
(Elsevier, 2013-10)
The effects of asymmetrical magnet faults on the rotor of permanent magnet synchronous machines (PMSM) are analyzed in the present work. Two different stator winding configurations, series and parallel connected windings, ...
Submersible permanent-magnet synchronous machine with a stainless core and unequal teeth widths = Maquina síncrona de imán permanente sumergible con núcleo de acero inoxidable y anchos de dientes desiguales.
(Universidad de Concepción.Departamento de Ingeniería EléctricaDepartamento de Ingeniería Eléctrica., 2021)
In recent years, permanent magnet synchronous machines (PMSM) have gained
popularity owing to their excellent performance compared with other kinds of electrical
machines in numerous applications. Furthermore, advances ...
