Calculation of the Voltage Unbalance Factor for High-Speed Railway Substations with V-Connection Scheme [PDF]

open access: yesElectronics, 2022
In France, high-speed railway lines are powered by a 2 × 25 kV/50 Hz electrification system. The substations include two single-phase transformers connected to the high-voltage electrical transmission network on different pairs of phases according to a so-called “V-connection scheme”.

An Alternative Methodology for Quantifying Voltage Unbalance Based on the Effects of the Temperatures and Efficiency of Induction Motors

open access: yesIEEE Access, 2022
Many unbalanced voltage conditions, which produce different effects on electric equipment, are associated with the same voltage unbalance factor. This fact hinders the precise association between the values of this index and the effects of voltage ...

Development and Analysis of a Sensitivity Matrix of a Three-Phase Voltage Unbalance Factor [PDF]

open access: yesIEEE Transactions on Power Systems, 2018
Unbalanced phase voltages in electricity networks prevent efficient and stable delivery of power and energy services from utility companies to end-users, and vice versa. While variations in voltage magnitude and power loss have been studied extensively, little attention has been paid to the development of linearized expressions to account for the ...

A Multiobjective Voltage Unbalance Factor for PV Hosting Capacity with Probabilistic ZIP Load Models [PDF]

open access: yes2018 IEEE Power & Energy Society General Meeting (PESGM), 2018
This paper proposes a multiobjective voltage unbalance factor to estimate single-phase photovoltaic (PV) hosting capacity in 3-phase residential networks. This factor is derived from a combination of various components, including zero and negative-sequence voltage unbalance factors associated with the inherent variability and uncertainty of both loads ...
