A Power-Quality Index to Assess the Impact of Voltage Harmonic Distortions and Unbalance to Three-Phase Induction Motors
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2010)
This paper discusses the need to simultaneously monitor voltage unbalance and harmonic distortions in addition to root-mean-square voltage values. An alternative way to obtain the parameters related to voltage unbalance ...
Voltage unbalance and harmonic distortion effects on induction motor power, torque and vibrations
(Elsevier Science Sa, 2016-11)
Voltage unbalance and harmonic voltage distortion affect the power, torque and vibrations on induction motors (IM). In this paper, we compute the frequency of the oscillations of the power, torque and vibrations due to ...

Improved Energy Conversion Process With Coupling Induction Motors And Invastigate Unbalanced Operation With Definition Of The Voltage Unbalance
(Universidade Federal de Santa Maria, 2015)
Evaluation of distribution system losses due to load unbalance
(2005-01-01)
Distribution network losses can vary significantly depending on the load unbalance. Here, an analysis of distribution system losses is presented that considers load unbalance and the effect of explicitly represented neutral ...
Optimal Multiobjective Control of Low-Voltage AC Microgrids: Power Flow Regulation and Compensation of Reactive Power and Unbalance
(Ieee-inst Electrical Electronics Engineers Inc, 2020-03-01)
The presence of single-phase distributed generators unevenly injecting active power in three-phase microgrids may create undesired upstream current unbalance. Consequently, voltage asymmetry and even active power curtailment ...
Análise do desbalanço de tensão em sistemas de distribuição de energia elétrica trifásicos à dois fios
(Universidade Federal de Santa MariaBrasilUFSMCentro de Tecnologia, 2023-02-13)
The growing demand for higher levels of electrical power in rural areas is a reflection of the
modernization of the countryside. This phenomenon has led energy concessionaires to invest
in technologies that enable the ...
Multiobjective approach for power flow and unbalance control in low-voltage networks considering distributed energy resources
(2017-07-01)
This paper proposes a multiobjective optimization technique that maximizes the active power generation from single-phase distributed generators, and minimizes the unbalance factor at the point of common coupling of the ...
