Metodologia para controle de reguladores de tensão em redes elétricas de distribuição utilizando simulação digital em tempo real
(Universidade Federal de Santa Maria, 2019-07-03)
Throughout its transportation, from generation to final consumption, the electrical energy fluctuates its voltage levels. These variations are natural and provided by the system itself, but without effective corrections, ...
Avaliação econômica dos erros da previsão de carga em sistemas hidrotérmicos aplicada a um modelo de despacho e fluxo de potência ótimos
(Universidade Federal de Santa Maria, 2019-07-05)
The economic load dispatch is one of the most important activities in the planning operation of an electric power system. Because, is the decision of power dispatch, took by the operator, that determines which transmission ...
Análise térmica de radiadores de transformadores elétricos utilizando o método de elementos finitos
(Universidade Federal de Santa Maria, 2019-07-10)
As any other electric equipment, transformers have efficiency lower than 100%. The “lost” energy is dissipated as heat in the active part of the machine and later this heat must be transferred to the outside environment, ...
