High impedance Fault Detection in Low Voltage Overhead Distribution based Wavelet and Harmonic Indices
Published by Enaam ALBANNA1, Alya H. AL-RIFAIE2, Ahmed A. Abdullah AL-KARAKCHI3, Northern Technical University (1,2,3) ORCID: 1. 0000-0002-3974-0116; 2. 0000-0002-7978-2193; 3. 0000-0003-1151-3015; Abstract. High-impedance fault HIF occurs when an energized conductor makes contact with a surface with a high impedance. Conventional overcurrent protection cannot detect this fault due to the low fault current, and thereContinue reading “High impedance Fault Detection in Low Voltage Overhead Distribution based Wavelet and Harmonic Indices”
Optimization of Field Upgrades of MV Power Lines using Evolutionary Algorithms
Published by Wojciech NITA1, Sylwester FILIPIAK2, PGE Dystrybucja S.A. Oddział Skarżysko-Kamienna (1), Politechnika Świętokrzyska (2) Abstract. This article elaborates on and supplements the research presented in earlier works [19,20,21] on planning for upgrading field MV power grids. While that study developed models for optimizing failure rates (SAIFI, SAIDI, MAIFI) for large areas of the grid,Continue reading “Optimization of Field Upgrades of MV Power Lines using Evolutionary Algorithms”
