Abstract

Urgency of the research. Ukraine has powerful dispersed generation resources. At the same time, one of the four measures proposed by the International Energy Agency for improving energy efficiency in the countries of the world is increasing the use of renewable energy sources in the total electricity production, including not the last role given to dispersed generation. Meanwhile, the consequence of the natural decrease in the levels of iron ore extraction in our country, at depths exceeding 1000-1500 m, that is, towards the projected ones, which already increases the energy intensity of its extraction and the decline of the con-capita ability on the world market. Target setting. The main purpose of this work is to synthesize the features of the electric power supply of iron ore enterprises, provided that they are introduced into the system of their electricity supply of distributed generation sources and analysis of the specifics of their operation. Actual scientific researches and issues analysis. Thus, the actual scientific-practical task is to study the peculiarities of the operation of systems of electricity supply of iron ore enterprises with the use of sources of dispersed generation in their distribution networks. Uninvestigated parts of general matters defining. Previously, it was proposed to install power plants at the crosscutting overheads, on dumps of quarries and other possible places of installation in the conditions of iron ore enterprises. However, the principles of the implementation of intelligent power supply management systems for the enterprises under consideration, especially when reconfiguring these systems, are not yet definitively defined. The research objective. The purpose of this work is to synthesize the features of the electricity supply of iron ore enterprises, provided that the sources of distributed generation are introduced into their electricity supply system. The statement of basic materials. In a number of previous studies, the authors justify the positive effect of the introduction of dispersed generation into the structure of the power supply systems of enterprises. The application of artificial neural networks in control systems and determination of electrical energy parameters of power supply systems of iron ore enterprises is proposed, which will allow multifactorial management and analysis of energy parameters in the implementation of distributed generation sources. The proposed approach for the implementation of artificial neural networks for modeling the reliability of the power supply system of iron ore enterprises with the introduction of dispersed generation can be presented with the help of artificial neural networks, which will improve predictability of generated electricity by dispersed generation in time. Conclusions. The model of reliability of the power supply system of the field-view enterprises in the implementation of dispersed generation can be represented using artificial neural networks, which will improve predictability of generated electricity by dispersed generation in time.
