Resumo: | The worldwide interest in renewable energy has increased, with a large emphasis on wind energy. In this sense, this work presents the supervision and control of an inverter for wind turbines. It uses a three-phase PWM converter with LCL filter for connecting the primary source to the grid. The state-space model of the system in discrete time is shown, as well as the design of the controllers for the grid current and DC bus voltage. The control loop of grid current uses the response of the DC bus voltage as reference. Furthermore, considering the development of wind turbines, a modulation strategy for converters with magnetically coupled parallel legs is proposed, as this makes possible to increase the processing of current by static converters. The modulation properly distributes the pulses between the switches and produces equivalent multilevel line-to-line voltage with reduced harmonic content. The circulating currents, which arise among the parallel legs, are limited through the use of a proportional controller and the addition of a double switching. On the other hand, some protections for connection of the primary source to the power grid are required by grid codes and must be respected. As a result, implementation methods of the necessary relays are also presented, which will be integrated into the inverter. Finally, simulation and experimental results are presented in all chapters to validate the proposed methods. |

Neste sentido, esta dissertação descreve em detalhes um sistema supervisório e o controle de inversor para turbinas eólicas conectadas à rede elétrica. Utiliza-se um conversor trifásico PWM a três fios com filtro LCL para a conexão da fonte primária à rede elétrica. A modelagem do sistema representada em equações de espaço de estados no tempo discreto é apresentada, bem como o projeto dos controladores para as malhas de controle da corrente da rede e tensão do barramento CC. A malha de controle da corrente da rede tem como referência a ação de controle da tensão do barramento CC. Além disso, tendo em vista o desenvolvimento das tecnologias dos aerogeradores, uma estratégia de modulação é proposta para conversores com pernas em paralelo, possibilitando o aumento da capacidade de processamento de corrente dos conversores estáticos. A modulação distribui adequadamente as comutações entre os interruptores e produz tensões equivalentes de linha multínivel com reduzido conteúdo harmônico. As correntes circulantes, que surgem entre as pernas em paralelo, são limitadas através do uso de um controlador proporcional e da adição de uma dupla comutação. Por outro lado, proteções para conexão da fonte primária a rede elétrica são exigidas por normas e devem ser respeitadas. Assim, também são apresentados métodos de implementação dos relés necessários, que serão integrados ao inversor. Por fim, resultados experimentais são apresentados em todos os capítulos, validando os desenvolvimentos teóricos.Coordenação de Aperfeiçoamento de Pessoal de Nível Superior - CAPESporUniversidade Federal de Santa MariaCentro de TecnologiaPrograma de Pós-Graduação em Engenharia ElétricaUFSMBrasilEngenharia ElétricaAttribution-NonCommercial-NoDerivatives 4.0 Internationalhttp://creativecommons.org/licenses/by-nc-nd/4.0/info:eu-repo/semantics/openAccessControle discretoConversores em paraleloConversores trifásicosEngenharia elétricaEnergia eólicaSistema supervisórioDiscrete controlElectrical engineeringParallel convertersSupervision systemThree-phase converterWind powerCNPQ::ENGENHARIAS::ENGENHARIA ELETRICADesenvolvimento de um sistema de controle e supervisão de inversor para turbinas eólicasSupervision and control of inverter for wind turbinesinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisPinheiro, Humbertohttp://lattes.cnpq.br/5900576762082210Carnielutti, FernandaBisogno, Fabio EckeZambra, Diorge Alex Báohttp://lattes.cnpq.br/0649840326082471Nicolini, André Miguel3004000000076006006006008aab6aac-f16b-4f23-8761-b8462475f0275f29fe12-b19e-44c3-9453-b8765f6bcb74afdd020f-c5be-4f2d-bdca-6882d625747d2a8f7d69-d52e-4aaa-bdca-c144ad62e7277416613a-184e-47dc-a2b8-333b1548a60breponame:Biblioteca Digital de Teses e Dissertações do UFSMinstname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMORIGINALDIS_PPGEE_2017_NICOLINI_ANDRE.pdf.pdfDIS_PPGEE_2017_NICOLINI_ANDRE.pdf.pdfDissertação de Mestradoapplication/pdf12129288http://repositorio.ufsm.br/bitstream/1/21419/1/DIS_PPGEE_2017_NICOLINI_ANDRE.pdf.pdfb3fdc3431eb044c6d619771475f05c78MD51CC-LICENSElicense_rdflicense_rdfapplication/rdf+xml;

The worldwide interest in renewable energy has increased, with a large emphasis on wind energy. In this sense, this work presents the supervision and control of an inverter for wind turbines. It uses a three-phase PWM converter with LCL filter for connecting the primary source to the grid. The state-space model of the system in discrete time is shown, as well as the design of the controllers for the grid current and DC bus voltage. The control loop of grid current uses the response of the DC bus voltage as reference. Furthermore, considering the development of wind turbines, a modulation strategy for converters with magnetically coupled parallel legs is proposed, as this makes possible to increase the processing of current by static converters. The modulation properly distributes the pulses between the switches and produces equivalent multilevel line-to-line voltage with reduced harmonic content. The circulating currents, which arise among the parallel legs, are limited through the use of a proportional controller and the addition of a double switching. On the other hand, some protections for connection of the primary source to the power grid are required by grid codes and must be respected. As a result, implementation methods of the necessary relays are also presented, which will be integrated into the inverter. Finally, simulation and experimental results are presented in all chapters to validate the proposed methods. |
