Harmonic propagation analysis in electric energy distribution systems
(2011-12-01)
An important alteration of the equivalent loads profile has been observed in the electrical energy distribution systems, for the last years. Such fact is due to the significant increment of the electronic processors of ...
Identificação de ilhamento elétrico em redes de transmissão de energia
(Universidade Tecnológica Federal do ParanáCuritibaDepartamento Acadêmico de Eletrotécnica, 2015-02-13)
The real-time operation of a power electric system (SEP) is an extremely complex task, and therefore requires several functions analysis and control of the network. Thus, interruption of the energy supply and the formation ...
Mathematical decomposition technique applied to the probabilistic power flow problem
(2011-05-31)
In this paper a framework based on the decomposition of the first-order optimality conditions is described and applied to solve the Probabilistic Power Flow (PPF) problem in a coordinated but decentralized way in the context ...
Inclusão de transformadores reguladores no algoritmo de análise de fluxo de potência
(Universidade Tecnológica Federal do ParanáPato BrancoBrasilDepartamento Acadêmico de ElétricaEngenharia ElétricaUTFPR, 2021-08-18)
The electric power systems (EPS) are non-linear systems that are constantly changing during its operation. Since the EPS’s creation, its complexity has grown fast, implying the needing of more precise analysis. This research ...
A decision support system for DC optimal power flow analysis on large scale interconnected system
(2011-01-01)
This paper proposes a decision support system for the National Interconnected System in Brazil. The developed decision support system is a tool that uses a DC optimal power flow to obtain the operating status of the network ...
Electrical modelling and power quality analysis of three-phase induction furnace
(2014-01-01)
The induction furnaces are loads having high power and nonlinear characteristic. The power consumption depends on the stage of melting metal in its interior and can cause serious problems on the electric power distribution ...
