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 ...

The different unbalance definitions applied to three-phase networks are presented shortly, and the unbalance causes and effects on induction motors and ASD are commented. The behavior of an ASD is analyzed when it is fed by an unbalanced voltage centering the attention on the characteristic and non-characteristic harmonic, rms values, K-derating factor,

This paper presents the main aspects observed in analyzing Complex Voltage Unbalance Factor (CVUF) behavior resulting from the variation of voltage magnitudes and angles. The goal is to identify possible incoherencies regarding the use of the CVUF, and also to investigate whether this factor is more sensitive to variations in magnitude or angles under ...

Overview of Power Factor Calculation Method for Nonsinusoidal and Unbalanced Systems
IEEJ TRANSACTIONS ON ELECTRICAL AND ELECTRONIC ENGINEERING, 2023With the increase of nonlinear loads (such as electric arc furnace, electrified railway, etc.) in power system, the harmonic distortion and unbalance of voltage and current are becoming more and more serious. The energy flow in the system is more complex
