This article describes the impact of the global digital economy on the technological development of the mineral sector in the world. Due to the different specifics of the legislative bases of the investigated regions, such as the USA, China, EU, and Africa, the development of digital transformation is presented on the example of the Russian Federation in the context of world trends. The article presents an analysis of the possibilities of using straight-through digital technology in prospecting, design, development, and use of mineral resources. It describes a structure promoting the development of applied digital technology through research–education centers and international competence centers. This structure would allow forming the new competencies for personnel working in the digital economy. The underfunding of the information and computing infrastructure could be a significant challenge to the digital transformation of the economy. Creating the conditions for a reliable and secure process of generating, storing, and using data is the basis for protection from the cybersecurity hazard that could act as a brake on technology advancement. This article discusses the organizational and technological priorities of the development of the mineral resource sector on the example of the Russian Federation. The challenges for the mineral resource complex resulting from global changes can be taken on through technological changes of the industry. The article gives a thorough description of issues related to technological developments in the raw materials sector, oil refining industry, development of integrated and advanced mineral processing systems, and the use of household and industrial wastes. The research presents basic technology contributing to sustainable development, starting from exploration and production forecasting and up to sustainable planning and distribution of material and energy resources based on real-time data. It also pays special attention to the possibilities of creating digital platforms for the mineral sector. Digital integration, combining research areas, personnel, processes, users, and data will create conditions for scientific and technological achievements and breakthroughs, providing scientific and economic developments in related industries and, above all, in the global mineral and raw materials market.

Fossil Energy in the Framework of Sustainable Development: Analysis of Prospects and Development of Forecast Scenarios

et al. 2021

View full text Add to dashboard Cite

In the next 20 years, the fossil energy must become a guarantor of the sustainable development of the energy sector for future generations. Significant threats represent hurdles in this transition. This study identified current global trends in the energy sector and the prospects for the development of energy until 2035. The importance of risk assessment in scenario forecasting based on expert judgments was proven. Three contrasting scenarios, #StayHome, #StayAlone, and #StayEffective, for the development of fossil energy, all based on comprehensive analysis of global risks by expert survey and factor analysis, were developed. It was concluded that fossil energy is mandatory with integration of advanced technologies at every stage of the production of traditional energy and of renewable energy as an integral part of the modern energy sector. Based on the results of the study, nine ambitious programs for the development of sustainable energy are presented. They require the creation and the utilization of a single interactive digital platform adapted to this purpose. It is a passport mandatory for the flexible interaction of energy production, its transmission, and its consumption in the perspective of having a future sustainable, reliable, and secured energy sector.

“…Then magnitude and phase of each component are calculated from coefficients according to (2). These values are then used to estimate positive and negative sequence components according to (4) and corresponding active and reactive instantaneous, average and oscillatory components of power (6)(7)(8). The calculated values are used to build a data packet according to Table 1.…”

Novel Approach to Collect and Process Power Quality Data in Medium-Voltage Distribution Grids

2021

View full text Add to dashboard Cite

The paper is devoted to the development of the structure of a fast and flexible data collecting system based on the proposed approach to measure power quality indicators in three-phase medium-voltage distribution grids with an example of a Mikhailovsky mining and processing plant. The approach utilizes the properties of a space vector, obtained from grid currents and voltages with disturbed waveform, to allow faster extraction of the harmonic components compared to traditional approaches, based on the direct Fourier-transform applied to a line or phase values. During the study, the concept of a universal measurement device was introduced, which allows fast estimation of the following values at the grid node: magnitudes and phases of voltage and current harmonic components, active and reactive power of harmonics and fundamental components, positive and negative instantaneous powers. The structure of interconnected measurement and control units for the considered grid node with simultaneous operation of two active variable frequency drives with active rectifiers was proposed in accordance with a concept of the Internet of things. The benefits of the proposed solution are shown by the example of the model of the grid node with two operating draglines and nonlinear load, which was developed in MATLAB/Simulink software. The proposed approach was utilized to produce distributed references for control systems of grid inverters to compensate nonlinear currents, which allowed to significantly improve THDi of the grid node input power.
