Estudo comparativo de técnicas de detecção de ilhamento para inversores PWM
(Universidade Tecnológica Federal do ParanáPato BrancoBrasilDepartamento Acadêmico de ElétricaEngenharia ElétricaUTFPR, 2018-06-12)
This monography deals with islanding detection and its impact on distribution networks when distributed generation systems are driven by DC-AC converters. In the three-phase inverter approach, the design of the LCL filter ...
Waveform selection for electrical impedance tomography
(Institute of Electrical and Electronics Engineers, 2013-04)
Electrical Impedance Tomography (EIT) is a non– invasive method that can be used to estimate the electrical conductivity of the head tissues. It is based on the measurement of electric potential on the scalp generated by ...
A mixed-integer LP model for the reconfiguration of radial electric distribution systems considering distributed generation
(2013-01-21)
The problem of reconfiguration of distribution systems considering the presence of distributed generation is modeled as a mixed-integer linear programming (MILP) problem in this paper. The demands of the electric distribution ...
