Abstract
The purpose of the research consists in developing logistics to form the economy of the road map of increasing energy efficiency of mining iron ore raw materials through applying automated control power complexes based on power supply systems with distributed power generation. The scientific article uses analytical and experimental research methods, namely, analytical methods of the probability theory and mathematical statistics; experimental methods – the theory experiment planning and conducting, mathematical modelling. The research deals with developing an automated control system (ACS) of power flows at iron ore underground mines which controls (distributes) power flows among consumers on an hourly basis without violating the technology of enterprise functioning (the option "power consumer-regulator"), determines and regulates the mode of power supply in appropriate periods of time (option "power consumer-generator"). In the cost of iron ore production, the energy component reaches 30% and tends to grow constantly. Therefore, methods of improving energy efficiency of iron ore underground mines as a component of the mining and metallurgical industry of Ukraine are urgent issues to be focused upon. The research enables developing logistics of forming the economy of the road map aimed at increasing energy efficiency of mining iron ore raw materials by applying automated controlled power complexes based on power supply systems with distributed power generation. The issue of implementing automated control of the power grid with potential distributed generation of power is considered. The use of a two-rate tariff without fuzzy automated control systems causes an increase in daily costs for consumed power with single-channel (drainage) and two-channel (ore flow and drainage) control by 12.88% and 7.1% respectively. The use of fuzzy controllers enables compensation of these losses. Application of an automated control system with fuzzy three-channel control (ore flow, drainage and ventilation) reduces the cost of power consumed by 4.45% (according to the data on Rodina mine, Kryvyi Rih). Modelling the fuzzy automated control system in modes of additional pumped storage power generation reveals potential opportunities for reducing total power consumption by 15%-35% (at the two-rate tariff) at iron ore underground mines.
