Metodologia para detecção e classificação de faltas em transformadores de potência por meio da Transformada Wavelet Discreta
(Universidade Federal de Santa Maria, 2018-08-28)
This thesis presents the development of a methodology for the detection and
classification of electrical transients in power transformers, for protection purposes. For this,
we analyzed several electrical transients ...
Compressibilidade de resíduos sólidos urbanos devido aos processos de biodegradação em um aterro sanitário
(Universidade Federal de Santa Maria, 2019-01-14)
The municipal solid waste (MSW) contain a high content of organic matter, which generates leachate and gases due to biodegradation processes, resulting in settlements. Storage capacity and slope stability are among the ...
Escoamento superficial e infiltração de água no solo em sistema plantio direto com “vertical mulching”
(Universidade Federal de Santa Maria, 2018-10-26)
The reduced infiltration of water into the soil in areas of intensive agriculture is one of the main
problems in hydrology. It decreases the water content in the soil profile and causes an increase in
surface runoff which ...
Reconfiguração automáticas das redes de distribuição de energia elétrica com monitoramento em tempo real
(Universidade Federal de Santa Maria, 2013-09-13)
In normal operation, the reconfiguration of distribution network can reduce losses,
balance loads and improve quality indicators. The increasing use of remote controlled
equipment in power systems leads the development ...
Fontes CA de potência: contribuição ao estudo e ao desenvolvimento de topologias híbridas
(Universidade Federal de Santa Maria, 2012-12-20)
In this thesis an study of AC Power Source (ACPS) topologies that guarantee the synthesis
of high quality voltage waveforms (in comparison to the reference signal) without
penalizing the system efficiency is carried out. ...
Alocação de canais para roteamento geográfico em redes de sensores e atuadores sem fio empregando a teoria dos jogos
(Universidade Federal de Santa Maria, 2012-05-25)
Wireless sensor and actuator networks are expected to grow quickly in size due to the
decreasing cost of nodes. For such large scale networks, the geographic routing algorithm
is a suitable approach. It finds a route for ...
Seleção de sistemas de geração de energia elétrica a partir de resíduos sólidos urbanos: uma abordagem com a lógica difusa
(Universidade Federal de Santa Maria, 2012-06-19)
Sustainability is becoming a major driving force in energy policy, leading to the development of different strategies and projects. Many of these strategies are related to the application of novel methodologies for selecting ...
Modelagem estocástica em usinas virtuais de energia utilizando transformada de incerteza
(Universidade Federal de Santa Maria, 2019-12-19)
The increase in distributed generation (DG) participation is a reality, influencing the way it
generates, distributes and consumes electricity. Virtual Power Plant (VPP) will play an
important role in integrating ...
Metodologia para geração e uso de energia elétrica de fontes renováveis com foco em tecnologias disruptivas e valores socioculturais locais
(Universidade Federal de Santa Maria, 2018-08-24)
This thesis was carried out with the purpose of creating a methodology to define the composition of the local energy use and to generate electric energy through the complementarity of the sources of renewable energies, ...
Estimação da seção em falta e processamento de alarmes em sistemas de potência utilizando um sistema híbrido fundamentado na heurística construtiva e na programação inteira
(Universidade Federal de Santa Maria, 2012-09-21)
This work proposes a methodology which is able to accomplish alarms processing and to
estimate fault section in electrical power systems. The purpose is to filter alarms generated
during a shutdown and indicate which ...
