20.500.12556/RUL-155874 Arc quality index based on three-phase Cassie–Mayr electric arc model of electric arc furnace In steel recycling, the optimization of Electric Arc Furnaces (EAFs) is of central importance in order to increase efficiency and reduce costs. This study focuses on the optimization of electric arcs, which make a significant contribution to the energy consumption of EAFs. A three-phase equivalent circuit integrated with the Cassie–Mayr arc model is used to capture the nonlinear and dynamic characteristics of arcs, including arc breakage and ignition process. A particle swarm optimization technique is applied to real EAF data containing current and voltage measurements to estimate the parameters of the Cassie–Mayr model. Based on the Cassie–Mayr arc parameters, a novel Arc Quality Index (AQI) is introduced in the study, which can be used to evaluate arc quality based on deviations from optimal conditions. The AQI provides a qualitative assessment of arc quality, analogous to indices such as arc coverage and arc stability. The study concludes that the AQI serves as an effective operational tool for EAF operators to optimize production and increase the efficiency and sustainability of steel production. The results underline the importance of understanding electric arc dynamics for the development of EAF technology. electric arc furnice Cassie–Mayr particle swarm optimization arc model equivalent circuit elektroobločna peč Cassie–Mayr optimizacija z rojem delcev model obloka nadomestno vezje true false true Angleški jezik Slovenski jezik Članek v reviji 2024-04-23 12:35:36 2024-04-23 12:35:36 2025-08-15 12:38:31 0000-00-00 00:00:00 2024 0 0 23 str. iss. 3, [article no.] 338 Vol. 14 Mar. 2024 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 621.365.2:681.5 2075-4701 10.3390/met14030338 189471491 metals-14-00338_(1).pdf metals-14-00338_(1).pdf 1 CDD89802B74ACF96671FD98FFE7B61FC 632cd523b11dd14b021c7ba149f821f8642275d9363bb4e64ca42093788c6488 df583f04-015d-11ef-9b79-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=182993 https://www.mdpi.com/2075-4701/14/3/338 1 3938e074-015d-11ef-9b79-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=182991 Fakulteta za elektrotehniko 0 0 0
