“…Considering this, the results of the study of adaptive compensation of magnetization currents of power transformers and displacement currents, which are typical for the extended intersystem (interstate) connections, are presented in [4][5][6][7][8][9][10]. Unlike with the currently existing stationary compensation solutions in [4][5][6][7][8][9][10][11][12][13][14][15][16][17], the use of additional software algorithms for identification of power equipment parameters is proposed. The proposed method allows to reduce the minimum tripping current to the level of 0.1-0.15 p.u.…”

“…Initially, this caused by the methodological error due to the insufficient mathematical rigor of the formulation of the research problem, and in some cases in using of unreliable primary (initial) parameters of the mathematical model during the performance of numerical experiments. All this inevitably causes errors in solving the problem when performing computational studies and can lead to subsequent misinterpretation of the obtained results, which is ultimately reflected in the erroneous view of the operation reliability and stability of the power system [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17].…”

“…Quite often, power sources of the examined electrical equipment are idealized, thereby introducing methodological roughness and possible distortions of the experimental results. However, due to the unjustified complication of the model and the inability to meet the computational performance requirements of modern microcontrollers, the use of a rigorous mathematical description of electrical power equipment transients may not be acceptable when solving the problem of improving and expanding of the functionality of microprocessor protection means and automatics [11][12][13][14][15][16][17][18].…”

“…Logistic activities use warehouses or transshipment facilities to constitute logistic networks, which enable the regional consolidation of transports for different customers and from different suppliers. Through freight consolidation, the utilization of the means of transportation can be increased, and therefore, overall transportation distance as well as CO2 emissions can be reduced [5,6].…”

The logistics network in the oil industry is highly inflexible, which arises from the production capabilities of crude oil suppliers, long transportation lead times, and the limitations of modes of transportation and energy planning and management. The paper considers the key factors for reducing costs and increasing the company’s profits in managing supply chains: demand management, efficient distribution of petroleum products among customers, better transportation scheduling, warehouse management, and quality and timeliness of information through the automation of the supply chain. And this principle is carried out within the framework of the logistics concept of supply chain coordination - Supply Chain Management. The paper also considers advantages from implementation of supply-chain management. Implementation of supply-chain management in the oil industry can help to reduce costs, increase the company’s profits in managing supply, and manage the planning of deliveries.

Development of Alloyed Pipe Steel Composition for Oil and Gas Production in the Arctic Region

et al. 2019

Gas and oil pipelines for the Arctic region must sustain low temperatures and high internal pressures of a corrosive active medium. Generation of new steel compositions for oil and gas pipelines is an urgent issue in order to ensure their high reliability. Low-carbon steels with a ferritic–pearlitic structure are normally used in pipe production, but they are unable to cope with increased market demands. The main objective of this study is to investigate the influence of the cooling rate on the structure and morphological characteristics of bainite, which determines the exploitation properties of the pipe steels. Dilatometric tests were carried out using a Gleeble 3500 complex. Optical microscope and scanning electron microscope analysis, with the computer image analysis system Thixomet PRO, were used to study the microstructure of steel. Hardness was measured in accordance with ASTM E-384. Morphological characteristics of bainite components that were formed at various cooling rates from 0.05 to 100 °С/s were defined. The novel result of this study is the continuous cooling transformation diagram of undercooled austenite of the steel containing 0.062% С; 1.80% Mn; 0.120% Mo; 0.032% Cr, 0.90% Ni and other elements (Al, Cu, V, Nb, Ti).
