IEEE Transactions on Energy Conversion, 2010
This paper evaluates the influence of the unbalance factors in calculating total copper losses, efficiency, power factor, input power, output torque, peak currents, and derating factor of the motor operating under unbalanced voltage system. The complete definition for the voltage unbalance is using complex voltage-unbalance factor that consists of its ...

International Review of Electrical Engineering (IREE), 2021
Voltage Unbalance (VU) is one of the most common power quality problems in industrial electrical systems and it is a subject of systematic study. This problem affects the operation and the efficiency of Induction Motors (IMs), which are the loads that demand more energy in the industrial sector with around 68%.

Calculation of the Voltage Unbalance Factor for 25kV-50Hz Railway Substations
2022 20th International Conference on Harmonics & Quality of Power (ICHQP), 2022This paper presents a method to determine the voltage unbalance factor for a 25kV/50Hz railway substation taking into account the power drawn by the trains. In order to correctly size a balancing system to be associated with the substation, it is necessary to calculate with precision the voltage unbalance factor.

Effect of nonlinearity and unbalance on power factor
2000 Power Engineering Society Summer Meeting (Cat. No.00CH37134), 2002Power factor has always been a very important parameter in the economics of power systems engineering. It is a very useful figure of merit that represents the utilization of the supply system. The notions established for the definition of power factor considering sinusoidal voltage and current waveforms do not hold true in the presence of distortion ...

2010 IEEE/PES Transmission and Distribution Conference and Exposition: Latin America (T&D-LA), 2010
In this paper, an analysis of the complex voltage unbalance factor (CVUF) in three-phase lines is offered, in order to orientate future experiments in the study of the effects of voltage unbalance. The geometrical loci for constant magnitudes of the CVUF are presented, considering that the angles of the voltages are constant, and considering that the ...
