“…Dependence between reactive power and voltage on SEM contact terminals is cubic, at this voltage is nonstandard and can be in the range of 500-3400 [5]. In fact capacity factor takes into account strengthened watering of operated well and is ~ 0.7 OE [6][7][8][9][10].…”

“…Currently, static capacitor banks with non-standard rated voltage are used to compensate reactive power in electrical complexes of producing wells with ESPI [11], which are connected directly to terminals of stator and submersible motor in well. This installation allows compensating reactive component of linear motor current in cable line and in OTSEM transformer and reducing the active power loss up to 6% [8,[12][13][14][15]].…”

The substitution scheme and the system of differential equations for electrotechnical complex of producing well are given. The mathematical and simulation models of electric drive of electric centrifugal pump installation with submersible individual compensating installation are developed. The scheme of inclusion and practical realization of individual compensating installation consisting of the static capacitor battery with non-standard nominal voltage which is connected directly to the stator clips of submersible electric motor in a well is proposed. The simulation model of electric actuator of the electric centrifugal pump allows one to simulate the operation mode of electric actuator in steady-state and transient modes, as well as the group start of electric drives of electrical complex of the producing well. The optimal level of outgoing line voltage, energy parameters and the optimal parameters of individual, node and centralized compensating installations, as well as the rational voltage level of the main substation were determined from simulation.

“…Expansion of production volumes, creation of new technologies in the metallurgical industry involves an increase in the volume of processing of raw materials and, as a result, an increase in emissions of dust and various gaseous substances into the atmosphere. With an increase in production volumes and, correspondingly, an increase in pollution, above the assimilation capacity of the environment, external costs are imposed on the enterprise [8]. We will present the results of financial analysis of three biggest Russian metallurgical companies, Severstal PJSC, Novolipetsk and Magnitogorsk Metallurgical Plants.…”

The development of the metallurgical industry requires investing in the environmental safety of processes and technologies of metal processing, as well as to the measures aimed at energy costs reduction. We will look at the economic impact of reducing production costs by saving resources and improving the efficiency of the energy complex. The financial effect of reducing energy consumption per unit of production can be achieved by optimizing the purchase of energy resources, modes of operation of technological and support equipment, improving the management of the company's energy complex. The article examines the most important indicators of the operating and financial activities of the three companies in the steel industry-Novolipetsk and Magnitogorsk Metallurgical Plants, as well as Severstal PJSC. The financial stability of these companies and the agility of their capital are quite high, and their fixed assets are financed by their own funds. Companies are also financially stable in the short term, as evidenced by the high current liquidity ratios (2 and above), and their own capital exceeds borrowing by 1.5 to 2 times. Thus, we can conclude that they are operationally efficient and have good financial sustainability in the short and long term.

The development of the metal processing industry requires paying attention both to the environmental safety of technologies of metal processing and to the energy costs. We will look at the economic impact of reducing production costs by saving resources and using environmental engineering tools. Minimizing the cost of protecting the air and water, soils and perennial plantings, recycling and disposal of waste and protecting natural landscapes are an important aspect of the company's development strategy. The article discusses the implementation of elements of strategies announced by the largest steel companies-Novolipetsk and Magnitogorsk Metallurgical Plants, and Severstal PJSC. The definition of strategy has been given. The strategy, on the one hand, is presented as an element of the enterprise's interaction with the external environment. On the other hand, it is seen from the point of view of the company's activity on three levels: corporate-business-functional, each of which, in its turn, consists of certain elements. We highlight the main elements of company's strategies, which are (generalized) as a combination of operational efficiency and cost reduction (functional strategies)-for all the companies, as well as market leadership (corporate strategy)-only for NLMP. The SWOT-analysis of the activities of all companies highlighted common characteristics of their traits: low growth of the world and domestic economy, low level of use of metallurgical capacity worldwide; the policy of protectionism that replaced globalization, the introduction of duties to enter the markets, the fact that domestic companies have their own resource base, the full production cycle, and other factors.As a general conclusion, despite the complexity of the external environment, companies try to adhere to the stated strategy and maintain high performance of operating efficiency and dividends. Companies can be considered to be confirming to their strategies and a system of planned indicators.
