Abstract

A large metallurgical enterprise has a complex multilevel hierarchical structure for managing energy consumption. High-precision commercial metering devices for the enterprise as a whole determine total electric energy consumption. At the lower level, that is, at the level of technological facilities, technical accounting of electric energy consumption is implemented by means of metering devices providing lower measurement accuracy. Besides, a great diversity of operating modes of production equipment results in various levels of electric energy consumption in different modes, which makes the task of energy consumption and rationing very complicated. Thus, high uncertainty level of energy consumption at the production level results in certain misbalance during accounting of energy consumption on the basis of data obtained from the production metering devices, which is used to solve the problems of consumption forecasting and rationing. It is necessary to find a balance of high accuracy of devices for commercial accounting of electric energy consumption and technical accounting of electric energy consumption by individual technological facilities of the enterprise.The paper proposes an algorithm for predicting and rationing electric energy consumption by technological facilities of a metallurgical enterprise based on a method of minimizing a general error in predicting electric energy consumption in an energy and metallurgical complex.The obtained energy characteristics can be used in solving problems of optimizing technological processes according to the criterion of minimum energy consumption, as well as for rationing energy consumption.
