Dissertação (Mestrado em Engenharia Elétrica.) – Instituto de Tecnologia, Universidade Federal do Pará, Belém, 2011. Disponível em: http://repositorio.ufpa.br/jspui/handle/2011/2896. Acesso em:.https://repositorio.ufpa.br/handle/2011/2896Due to the study of power systems in real plants as a hydroelectric power plant it’s not common because the risks and costs involving their operation, it is preferred to conduct computational mathematical models of this system solving problems and developing new technologies. However, computer-realized models do not provide the visible, audible and tactile experience that a real physical model can offer. Therefore, in this work, it is presented a description and modeling of a micro-generation system of 10kVA, which is a real physical system, composed of a DC motor, a synchronous generator and transformers, also called micromachine system, which makes part of the infrastructure of the Laboratory of Electrical Engineering at UFPA. For this system, through this work and the Moraes’ work (2011), were developed electronic subsystems and computer drives, automation and control to operate it safely and to support research in control of power systems, as well as the development of academic work. In this same context, it is proposed an emulation technique of the dynamic of a hydraulic turbine controlling by the power applied to DC motor micromachine system, which was developed mainly for the purpose of supporting the study and development of techniques of speed regulation for hydraulic turbines. It also will present a proposal for a digital speed governor for hydraulic turbines based on the canonical structure RST digital control, whose parameters are designed by two techniques studied in this work. And to prove the effectiveness of tools for hardware, software and theory developed in this work, results of experiments performed at the micromachine system will be presented and analyzed.porAcesso AbertoControle digitalRegulação de velocidadeTurbinas hidráulicasMicromáquinaMotor CCSpeed controlDigital controlHydraulic turbineHybrid simulationHybrid simulationMicromachineDC motorDissertaçãoCNPQ::ENGENHARIAS::ENGENHARIA ELETRICA::SISTEMAS ELETRICOS DE POTENCIA::MAQUINAS ELETRICAS E DISPOSITIVOS DE POTENCIACNPQ::ENGENHARIAS::ENGENHARIA ELETRICA::SISTEMAS ELETRICOS DE POTENCIA::GERACAO DA ENERGIA ELETRICACNPQ::ENGENHARIAS::ENGENHARIA ELETRICA::ELETRONICA INDUSTRIAL, SISTEMAS E CONTROLES ELETRONICOS::AUTOMACAO ELETRONICA DE PROCESSOS ELETRICOS E INDUSTRIAISCNPQ::ENGENHARIAS::ENGENHARIA ELETRICA::ELETRONICA INDUSTRIAL, SISTEMAS E CONTROLES ELETRONICOS::ELETRONICA INDUSTRIAL
