Ways to Ensure Electromagnetic Compatibility of Powerful Frequency Converters in Internal Power Supply Systems of Industrial Enterprises in the Presence of Resonance Phenomena

Power Factor Modelling and Prediction at the Hot Rolling Mills’ Power Supply Using Machine Learning Algorithms

“…Harmonic disturbances in the electrical grid may damage electronic and electrical equipment [18]. Harmonics can cause overheating in frequency or lamination control problems in hot rolling mills.…”

“…Power losses or outages can induce unexpected shutdowns, causing equipment failure. Process continuity may require interruption management [15,16,18].…”

“…Voltage drops have significant repercussions for production. Malfunctioning of the electric drive in the technical installation causes interruptions in the technological process, resulting in equipment breakdowns, rejects, and the underproduction of products [18].…”

“…Monitoring and managing equipment power quality are crucial for hot sheet operation and product quality. Harmonic filters and surge protection devices can improve electrical quality and reduce disturbances in the rolling process and completed product [12,16,18].…”

“…Harmonic currents are caused in large part by the widespread use of power converters, which are found in many electrical and electronic systems, including household appliances. While the power of household appliances is relatively low [21,22], harmonic currents cause significant power losses in industrial electrical installations due to the very high power [15][16][17][18]. As a result, many papers in specialized journals present research on the presence of harmonic currents, load unbalances, or overcurrents.…”
