Experience in implementing energy and resource saving technologies in a electric power supply systems of metallurgical production

The article considers a set of scientific approaches and technical measures aimed at improving the efficiency of power supply to ferrous metallurgy enterprises, currently being designed by the scientific schools of the Nosov Magnitogorsk State Technical University together with PJSC “Magnitogorsk Iron and Steel Works”. The principles of the formation of mathematical models for energy consumption, the basics of their optimization, as well as practical issues of rationing and planning energy consumption and operational management of the energy economy are described herein. The study offers examples of the implementation of energy-saving measures at own factory power plants, as well as at such energy-intensive facilities as arc steelmaking furnaces and rolling mills. The experience of PJSC “Magnitogorsk Iron and Steel Works” with regard to the introduction of modern automation tools in the energy sector and power supply systems within the framework of the promising development program “Industry 4.0” is presented.
