The effect of the traditional energy saving mode on process engineering is decreasing, so the idea of system energy saving is developing vigorously. This paper summarizes the existing studies on energy saving from three aspects—energy saving technology, energy management, comprehensive evaluation or analysis—and clearly finds that related studies on energy saving have been gradually promoted to promote the development of system energy saving in the whole process engineering process. Among them, the calculation of energy saving brought by energy saving technology is a difficult point in the research. This paper proposes a novel calculation method of energy saving by taking the iron and steel production process (ISPP) as an example. According to the actual data provided by a steel plant in China, the calculation method is validated effectively.

During the implementation of energy efficiency policy in the Russian Federation, issues related to the analysis of the electric power quality (QE) in the power supply systems (PSS) of industrial enterprises are of particular importance. Much attention has been paid in recent years to the problem of the electric power quality both in our country and abroad due to significant economic damage caused by deterioration of QE indicators. The improvement of the main indicators is an integral part of the energy and resource saving policy, the role and importance of which are ever increasing as part of the implementation of the country's energy program. In the course of work, comprehensive studies of electric power quality indicators were carried out using modern measuring devices (AR5, PKK-57), their further analysis using software (DELPHI, MathCad, Excel) and criterial evaluation of theoretical and experimental studies. A method of experimental study of the amplitudefrequency characteristics of the higher voltage harmonics in the 6 kV power supply system of OJSC Pobedit and OJSC Electrozink has been developed. Comparison of experimental data on the harmonic components of currents and voltages and the data of analytical calculations in Fourier series have shown good convergence of the results. The results of the study of nonsinusoidal voltage in the power supply systems, according to the developed calculation methods, were introduced into production at the enterprises of non-ferrous metallurgy of the Republic of North Ossetia-Alania: OJSC Electrozinc (zinc production), OJSC Pobedit (hard-alloy production).

“…The production process for manufacturing steel is energy-intensive and requires a large amount of resources, thus the energy efficiency of steel industry has a direct effect on global energy consumption (He and Wang, 2017). However, due to the currently energy crisis caused by the reduction of the fossil fuels, new energy-efficient technologies and strategies are needed in order to ensure a sustainable energy supply of this industry (Tang et al, 2014). Researches focused on improving the energy-efficient technologies, and management of the steel industry has therefore a high scientific, economic and social interest (Zhao et al, 2015).…”

In this paper, a new strategy for robust control of temperature in a steel slab reheating furnace with large time delay uncertainty based on fractional-order controllers combined with a Smith predictor is proposed. A time delay model of the preheating zone of this process is used, obtained from an identification procedure applied in a real industrial furnace. It is shown that this process experiences very large time delay changes. A fractional-order integral controller embedded in a Smith predictor structure (FI-SP) is designed, which is robust to changes in such time delay. Simulated results of a standard Proportinal Integral Derivative (PID) controller, a PID controller embedded in a Smith predictor and the proposed FI-SP controller are compared. Six performance indexes have been used in this comparison. The analysis of these indexes shows that the designed FI-SP controller exhibits the most robust behavior (lowest indexes averaged in all the range of time delay variation) for ranges that include large time delays. Then the robustness features of the FI-SP controller outperform the other integer order controllers in the time responses both to set-point changes and to step disturbances. Therefore, this controller guarantees the best accuracy of temperature control. The designed FI-SP guarantees system stability and robust performance for a high range of plant time delay uncertainties.
