Conversor CA-CA de elevado fator de potência para aplicações com geradores de Ímã permanente
(2010-12-01)
This paper proposes and describes a high power factor AC-AC converter for naval applications using Permanent Magnet Generator (PMG). The three-phase output voltages of the PMG vary from 260 Vrms (220 Hz) to 380 Vrms (360 ...
MILP branch flow model for concurrent AC multistage transmission expansion and reactive power planning with security constraints
(Inst Engineering Technology-iet, 2016-09-02)
This study presents a mixed-integer linear programming (MILP) model to solve the simultaneous transmission network expansion planning (TNEP) and reactive power planning (RPP) problem. The proposed model considers reactive ...
Milp Branch Flow Model For Concurrent Ac Multistage Transmission Expansion And Reactive Power Planning With Security Constraints

Análise dos impactos das correntes harmônicas nas redes de distribuição causados pela grande penetração de geração fotovoltaica
(Universidade Tecnológica Federal do ParanáPato BrancoBrasilDepartamento Acadêmico de ElétricaEngenharia ElétricaUTFPR, 2022-06-13)
In this work, the effects of harmonic currents in a distribution network system with several photovoltaic inverters were analyzed. In the first part, the inductivecapacitiveinductive (LCL) filter sizing methodology was ...
Accidental torsion due to overturning in nominally symmetric structures isolated with the FPS
(JOHN WILEY & SONS LTD, 2003)
Overturning of a structure causes variations in the normal loads of the isolators supporting that structure. For frictional isolators, such variation leads to changes in the frictional forces developed and, hence, in the ...
Desenvolvimento de protótipo para medição de indutância em corrente e frequência nominal para conversores estáticos
(Universidade Tecnológica Federal do ParanáCuritibaBrasilDepartamento Acadêmico de EletrotécnicaEngenharia Elétrica com Ênfase em AutomaçãoUTFPR, 2015-07-02)
This work seeks to develop a reliable inductance measuring converter through a buck in nominal current and operating frequency. The text presents the prototype specification, construction specification and the data acquiring ...
On the robustness of structural risk optimization with respect to epistemic uncertainties.
(Redding, 2012)
In the context of structural design, risk optimization allows one to find a proper point of balance between the concurrent goals of economy and safety. Risk optimization involves the minimization of total expected costs, ...

An experimental study of nominally symmetric and asymmetric structures isolated with the FPS
(WILEY, 2003)
This experimental investigation deals with the earthquake behaviour of a nominally symmetric and a mass-asymmetric three-storey structural model isolated with the frictional pendulum system (FPS). Both accidental and natural ...
