Influence of double excitation AC/DC in the reactive power demand of 3-phase transformers
(IEEE, 1999-12-01)
In this work it is discussed the performance of the reactive power demand in three-leg transformer core and three-phase transformer bank, under different conditions of AC/DC double excitation. In order to analyse the ...
Instantaneous complex power applied to three-phase machines
(1993-12-01)
The theory presented in this paper was primarily developed to give a physical interpretation for the instantaneous power flow on a three-phase induction machine, without a neutral conductor, on any operational state and ...
A Short Note on a Nonlinear System vibrations under Two Non-Ideal Excitations
(2003-10-01)
This paper describes a nonlinear phenomenon in the dynamical behavior of a nonlinear system under two non-ideal excitations: the self-synchronization of unbalanced direct current motors. The considered model is taken as a ...
Non-linear energy harvesting system efficiency comparison from periodic to non-ideal excitation
(2014-01-01)
Dynamics of a non-linear energy harvesting is affected by excitation source and to explore efficiency it is necessary to understand which region offers more energy and the influence of a forced periodic vibration related ...
Reduction of torsional vibrations excited by electromechanical interactions in more electric systems
(IEEE-Inst Electrical Electronics Engineers, 2021)
This paper studies the excitation of torsional vibrations by electromechanical interaction after the connection of electrical loads. Electrical generation and power system in aircraft are becoming of key importance, ...
Influence of Excitation Signal on Impedance-based Structural Health Monitoring
(Sage Publications Ltd, 2010-09-01)
The electromechanical impedance (EMI) technique has been successfully used in structural health monitoring (SHM) systems on a wide variety of structures. The basic concept of this technique is to monitor the structural ...
