The State and Prospects of Development of Power Supply Systems of Metallurgical Enterprises with On-Site Power Plants

Abstract

The article considers the features of design of industrial power supply system of metallurgical enterprises with on-site electrical power generation. The problems of increasing the efficiency of the main electrical equipment of on-site power plants are formulated. The analysis of development trends in the energy sector of Russian metallurgy is carried out, on the basis of which the importance of industrial on-site power plants is shown. The problem of choosing a generator automatic excitation control system of on-site power plants is con-sidered and possible ways of its solution are given. The task of regime optimization of industrial on-site power plants is considered and original optimization algorithms are presented. Methods of increasing the reliability of power supply of critical equipment and mechanisms involved in the technological process of thermal power plants are proposed. The urgency of the tasks of complex automation and digitalization in the industrial power supply systems is shown, while the special meaning of "digital twins" is noted. Possible prospects for the development of on-site power plants in the context of the decarbonization policy and the transition to alternative energy are considered.
