Modelo de dimensionamento de geradores síncronos com ímãs permanentes de superfície utilizando ímãs de ferrite
(Universidade Tecnológica Federal do ParanáPato BrancoBrasilDepartamento Acadêmico de ElétricaEngenharia ElétricaUTFPR, 2018-06-15)
This work proposes the use of an analytical sizing model to determine the main geometric dimensions of a synchronous generator with permanent surface ferrite magnets. Firstly, some of the tax conditions proposed by the ...
A Model-Based Approach for Small-Signal Stability Assessment of Unbalanced Power Systems
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INCPISCATAWAY, 2012)
In this paper, a modeling technique for small-signal stability assessment of unbalanced power systems is presented. Since power distribution systems are inherently unbalanced, due to its lines and loads characteristics, ...
Combined control of a distribution static synchronous compensator/flywheel energy storage system for wind energy applications
(Institution of Engineering and Technology, 2012-06)
The integration of wind power generation in power systems is steadily increasing around the world. This incorporation can bring problems onto the dynamics of power systems owing to the lack of controllability over the wind ...
Filtro ativo paralelo aplicado à compensação de harmônicos e desbalanços de corrente em sistema isolado de microgeração de energia elétrica
(Universidade Federal de Santa MariaBrasilUFSMCentro de Tecnologia, 2023-07-12)
This course completion work aims to present a system capable of compensating for unbalanced and harmonic currents from unbalanced and non-linear loads in an isolated power generation system. The isolated generation system ...

Subsynchronous Resonance Mitigation using Variable-Speed Wind Energy Conversion Systems
(Institute of Electrical and Electronics Engineers, 2013-05)
This work proposes a strategy to mitigate subsynchronous resonance (SSR) in synchronous generators using variable-speed wind energy conversion systems (WECSs) based on full converter wind turbines. A supplementary active ...
Multichannel Detrended Fluctuation Analysis Reveals Synchronized Patterns of Spontaneous Spinal Activity in Anesthetized Cats
(2011)
The analysis of the interaction and synchronization of relative large ensembles of neurons is fundamental for the understanding of complex functions of the nervous system. It is known that the temporal synchronization of ...
Método de sincronização aplicado a conversores PWM trifásicos
(Universidade Federal de Santa MariaBREngenharia ElétricaUFSMPrograma de Pós-Graduação em Engenharia Elétrica, 2006-07-17)
In the last decade, disturbances in the electrical system have been increased, mainly due to proliferation of nonlinear loads. As a result harmonic distortion, voltage unbalance and frequency variations are becoming a ...
Regulação de sistema de geração baseado em gerador de indução autoexcitado empregando gerador síncrono como compensador de reativos
(Universidade Federal de Santa MariaBrasilEngenharia ElétricaUFSMPrograma de Pós-Graduação em Engenharia ElétricaCentro de Tecnologia, 2022-08-19)
This master’s thesis presents the development of a Self-excited Induction Generator (SEIG) and
a Synchronous Generator (SG) based generation system, where the SG acts as reactive power
compensator. In the generation ...
