A Strategy to Eliminate Instantaneous Active Power Oscillations and Reduce High Currents in the DFIG During Asymmetric Voltage Sags

Autor: Joacillo L. Dantas, Francisco K. de A. Lima, Paulo H. P. Silva, Jean M. L. Fonseca, Carlos G. C. Branco

Publikováno v: Eletrônica de Potência, Vol 24, Iss 2 (2019)

Wind turbines are widespread around the globe, and the number of windfarms connected to the grid is continually increasing. The Doubly-Fed Induction Generator (DFIG) plays an important role, since it is one of the most used configurations for wind po

Modelo Simplificado para as Sequências Positiva e Negativa do Sistema de Conversão Eólico-Elétrico Baseado em Gerador de Indução Duplamente Alimentado

Autor: Celso R. Schmidlin Jr, Francisco Kleber de A. Lima, Tobias R. Fernandes Neto, Carlos G. C. Branco

Publikováno v: Eletrônica de Potência, Vol 23, Iss 2 (2018)

Para melhorar o desempenho e aumentar a suportabilidade a afundamentos de tensão do gerador de indução duplamente alimentado durante desequilíbrios nas tensões da rede elétrica, muitos estudos propõem que o sistema de controle também atue nas

Providing Ancillary Services with Wind Turbine Generators Based on DFIG with a Two-Branch Static Converter

Autor: Ernande Eugenio C. Morais, Francisco Kleber de A. Lima, Jean M. L. Fonseca, Carlos G. C. Branco, Lívia de A. Machado

Publikováno v: Energies, Vol 12, Iss 13, p 2490 (2019)

This work aims to analyze and validate through mathematical modeling and experimental results, in a three-phase three-wire electrical system, the technical viability of a static power converter with a two-level topology with only two controlled branc

A Non-isolated Single Phase Ups Topology With 110v/220v Input Output Voltage Ratings

Autor: Carlos G. C. Branco, Cícero M. T. Cruz, René P. Torrico-Bascopé, Fernando L. M. Antunes

Publikováno v: Eletrônica de Potência, Vol 11, Iss 2, Pp 111-118 (2006)

A circuit configuration of a single phase non-isolated on-line uninterruptible power supply (UPS) with 110V/220V input output voltage ratings is proposed, allowing the bypass operation without a transformer even if the input voltage is different of t

Proposal of Three-Phase High Frequency Transformer Isolation UPS Topologies

Autor: Carlos G. C. Branco, René P. Torrico-Bascopé, Cicero M. T. Cruz, Francisco K. A. Lima

Publikováno v: Eletrônica de Potência, Vol 16, Iss 4 (2011)

A family of double conversion three-phase uninterruptible power system with power factor correction and high-frequency transformer (HFT) isolation topologies is presented in this work. This might be an alternative compared to large conventional UPS s

A High Frequency Transformer Isolation Ups System With 110V/220V Input Voltage

Autor: René P. Torrico-Bascopé, Demercil S. Oliveira Jr., Carlos G. C. Branco, Fernando L. M. Antunes

Publikováno v: Eletrônica de Potência, Vol 11, Iss 3 (2006)

This work proposes an isolated double conversion UPS with power factor correction using a high frequency transformer, and input voltages equal to 110V/220V. The arrangement is suitable to rack structures because it has small size and reduced weight.
