Analysis of the Response of L and LCL Filters in Controlled Rectifiers used in Wind Generator Systems with Permanent Magnet Synchronous Generators
(2018)
This paper presents the comparative study of the response of a Controlled Rectifier in a wind power system with a synchronous permanent magnet generator when a L filter and a LCL filter are used between the generator and ...
Experimental demonstration of a noise-tunable delay line with applications to phase synchronization
(Elsevier Science, 2015-05)
In this paper we propose and demonstrate a discrete circuit capable of generating arbitrary time delays dependent on noise, either added externally or already present in the signal of interest due to a finite signal-to-noise ...
O efeito de técnicas de relaxamento em atletas iniciantes do nado sincronizado
(Universidade Tecnológica Federal do ParanáCuritibaBrasilBacharelado em Educação FísicaUTFPR, 2017-08-02)
The Synchronized swimming, as well as other competitive sports, can cause negative stress in athletes due to their unique characteristics and the complexity of the sport. On the other hand, the objective of the study is ...
Proteção contra perda de excitação em geradores síncronos: uma nova proposta utilizando o método do cálculo contínuo da impedância aparente
(Universidade Federal de Santa MariaBREngenharia ElétricaUFSMPrograma de Pós-Graduação em Engenharia Elétrica, 2015-10-16)
This work presents a new Loss-of-Excitation in synchronous generators protection scheme based on the Continuous Apparent Impedance Calculation. This methodology aiming to improve security and dependability to the ANSI 40 ...
Binary position sensor for synchronous machines based on a serial n-bit sequential code
(IEEE, 2013)
This work presents the design of an absolute position encoder with n-bit resolution based on a serial sequential code to measure rotor position in synchronous machines. The encoder is capable of define 2n positions minimizing ...

A fault detection technique for variable-speed wind turbines using vibrations and electrical measurements
(Sociedade Brasileira de Eletrônica de Potência, 2014-11)
A technique for detecting faults in variable speed wind turbines with permanent magnet synchronous generators is proposed. The proposal consist on sampling and process vibration signals at constant position intervals, in ...
Nonlinear observer-based control for PMSG wind turbine
(Pergamon-Elsevier Science Ltd, 2016-10)
This paper introduces a mechanical sensorless control strategy to be used in variable speed wind energy conversion systems based on permanent magnet synchronous generators. The goal of the control strategy is to track the ...
Synthesis of Sinusoidal Waveform References Synchronized With Periodic Signals
(Institute of Electrical and Electronics Engineers, 2008-03)
This paper proposes a novel method to generate a sinusoidal waveform synchronized with any measurable periodic signal whose frequency is within a given neighborhood. The synthesized sinusoidal signal could be used as a ...
