Abstract:

The paper shows that the operational management of the power consumption regime is reduced to solving the problem of operational forecasting of the enterprise's load. The paper analyzes the works devoted to the forecasting of electric loads of power systems and industrial enterprises. It is shown that in order to achieve the required forecast accuracy, it is advisable to use adaptive forecasting procedures and, in particular, to use artificial neural networks. The use of artificial neural networks for forecasting the load of industrial enterprises is due to their properties, such as the abilit

Abstract:

Cement production is an industry that consumes a lot of electric energy. During the period of power shortage in China, the government encouraged multi-channel financing to run electricity to alleviate the power shortage problem of large industrial users. Therefore, many cement enterprises have established their own power plants. This paper analyses the basic electrical characteristics of the cement industry, classifies the loads of enterprises, and studies the regulation characteristics of various types of equipment.

Abstract:

Diagnostics of electrical equipment at industrial enterprises is an urgent task, since the failure of the main and auxiliary electric drives can lead to significant economic losses for the enterprise. The main share of failures of asynchronous motors is caused by their overload and, accordingly, overheating of the stator winding. Such overheating leads either to an interturn circuit and engine failure, or to a significant reduction in its resource. Therefore, winding temperature control is an important task. In this paper, we propose an algorithm for calculating the temperature of an induction

Based on complex studies, conclusions were drawn about the structure of electrical loads in coal mines, which are characterized by a non-linear and non-symmetric nature. The problem of higher harmonics and interharmonics with limited short-circuit power, which is characteristic of an autonomous power supply system, is highlighted.
