Modified Droop Control For Low Voltage Single Phase Isolated Microgrids
(IEEENew York, 2016)
RESONANT (P plus RES) CONTROLLER APPLIED TO VOLTAGE SOURCE INVERTER WITH MINIMUM DC LINK CAPACITOR
(Ieee, 2011-01-01)
Voltage source inverters use large electrolytic capacitors in order to decouple the energy between the utility and the load, keeping the DC link voltage constant. Decreasing the capacitance reduces the distortion in the ...
Theoretical analysis of the voltage unbalance factor to characterize unbalance problems in induction motors
(Corporación Universidad de la Costa, 2021)
Assessment of branch outage contingencies using the continuation method
(2014-01-01)
This paper provides a contribution to the contingency analysis of electric power systems under steady state conditions. An alternative methodology is presented for static contingency analyses that only use continuation ...

Measurement of unbalanced voltages in three-phase induction motors using acoustic transducers and zero-crossing-weighted energy
(2021-08-23)
In modern industries, transducers and measurement systems have been largely applied for equipment monitoring. In this context, three-phase induction motors (TIMs) are the main focus of predictive maintenance due to their ...
Emprego de um comutador eletrônico de taps para regulação de tensão em redes elétricas a partir do modelo de carga
(Universidade Federal de Santa MariaBrasilEngenharia ElétricaUFSMPrograma de Pós-Graduação em Engenharia ElétricaCentro de Tecnologia, 2018-08-31)
This doctoral thesis proposes a method for regulating the secondary voltage of distribution systems
based on the identification of ZIP models of the load (constant impedance, constant current and
constant power) at the ...
