Authors: Dolgih Roman , Suvorov Ivan , Palkin George , Kakaurov Sergey , Morozova Marina
Published: July 2021

Up to 38% of asynchronous motor (AM) failures are caused by damage to the stator insulation. Despite the wide variety of methods, the reliability of determining the inter-turn short circuits of stator windings under operating voltage still remains at a low level. The existing methods for diagnostics of asynchronous motor failure of the interturn short circuit of stator winding have been examined. New diagnostic methods for individual parameters developed in the course of the previous study are described. A new diagnostic method is formulated, on the basis of which the research work is carried out. The method will allow us to constantly monitor the technical condition of the stator winding, and identify its damage at an early stage of their development. Diagnostics can be performed without dismantling the engine and without removing it from the working process. The microprocessor unit is implemented for diagnostics of the technical condition of AM introducing this method. Moreover, the software and hardware complex is implemented for diagnostics of the technical condition for AM. The results of experiments on a laboratory stand with inter-turn AM closures are presented, which confirm the higher reliability of monitoring.

Chalcopyrite CuFeS2is a known semiconductor mineral with a wide range of unique physical and chemical properties. These materials can be used as elements of solar batteries, coherent and incoherent sources of polarized radiation, in photovoltaic, thermoelectric and spintronic devices. Despite the relatively large number of studies on CuFeS2, many questions about its magnetic and electronic properties, are still outstanding. In this paper we were carried out studies of the distribution of the electron density and spin density in the nuclei of iron and copper in the semiconductor mineral CuFeS2. Special attention was devoted to interrelation of electronic and spin subsystems of the compound. The results of studies of the compound obtained in NMR63,65Cu local field at low temperatures were used to perform the corresponding analysis. The cluster approach was used. The biggest cluster had Cu9Fe10S28-4formula. Calculations were carried out in the framework of restricted self-consistent Hartree - Fock with open shells (SCF-LCAO-ROHF), MINI basis. The calculations were made with the “foundation” on the quadrupole parameters (quadrupole νQ frequency and the asymmetry parameter of the electric field gradient tensor η), obtained from the experiment. Study of electron density maps were performed for the regions containing chains of Fe-S-Cu and S-Fe-S for the different layers of metals and sulfur atoms. It is shown that the nature of the connection of iron atoms belonging to neighboring layers with sulfur atoms of the intermediate layer is different, which is reflected on the electron density distribution.

Published: July 2021

This article discusses the specific features of such a product as reactive power. The degree of reactive power compensation both in the domestic electric power industry and in most industrialized countries is clearly insufficient. The possibilities available in electric grids, at power plants and at consumers of electricity for coordinated regulation of reactive power and voltage levels are not fully used. The main factors influencing the formation of the reactive power market in the electric power industry are revealed. The proposed market is based on the organization and implementation of qualified selection of reactive power suppliers. The scheme of the price bid of reactive power suppliers, developed on the fundament of the cost structure of various types of reactive power suppliers is proposed. Rational regulation of reactive power is currently not considered as an economic problem, but it is one of the main tools for managing the efficiency of EPS. The proposed organizational mechanism of pricing for reactive power and the qualified selection of its suppliers is aimed at determining the range of suppliers of reactive power capable of meeting the demand for it with the least costs, as well as to stimulate investments in the construction of new sources of reactive power.

Published: July 2021

There is usually no information about permissible error of current transformers in modes succeed by large relative short-circuit current, at which microprocessor-based protections operate stably. By this reason, it is necessary to use data, defined for analog relays. It leads to value appreciation of a project because it is often essential to reduce current transformers’ error in case of a short circuit fault. Therefore, it is necessary to define the value of current transformers’ error, permitted for impedance relays. Conclusions of fundamental and applied sciences (mathematical analysis, theoretical foundations of electrical engineering, theory of simulation), analytical methods of researching nonlinear circuits and digital signal processing were used. A simulation model was created for setting overall tests of the current trans-former (CT) system. It was a relay protection device that reflected all the important properties of studied objects and allowed an analysis of digital distance protection’s operation at high levels of short-circuit currents. The factors influ-encing over digital distance protection’s operation in case of deep saturation of CTs were revealed, and a certain algorithm for definition of the permissible CT errors was proposed. Stable operation of digital distance protection was observed in case of a fault nearby the place of current transformers’ setting in all theoretically possible combinations of electrical system’s power and length of a protected electric power transmission line. It is valid if electric load choice is carried with account for stable protection’s operation in condition of a fault in the computational point and if voltage swell in secondary wirings is infeasible.

Authors: Litvinov Ilya , Naumova Aleksandra , Titov Vasiliy , Trofimov Andrey , Gracheva Elena
Published: July 2021

Special attention is paid to high-speed relay protections’ operation in transient modes due to a number of major failure events that have occurred over the past 10 years in the power system of the Russian Federation. Operation of power transformer’s differential protection in case of internal short circuit is studied in this research. False blocking of protection is possible in such mode due to saturation of current transformers. A value of blocking time may exceed the maximum permissible short-circuit disconnection time under conditions of maintaining the dynamic stability of the power system. Primary and secondary currents in transient modes are obtained by simulation of short circuits. Windings of the modeled current transformers are connected in a star to a null wire. RMS values are calculated using a mathematical model of the Fourier filter. The current transformers were checked according to the methods declared in PNST 283-2018 and GOST R 58669-2019. The analysis carried out in this work allows to estimate possibility of long-term blocking of the differential protection of a power transformer in case of internal short circuit, especially in case of significant value of time constants.

Design of an acrylic wastewater treatment method based on deep oxidation technology
Authors: Liang Wei
Published: July 2021

Acrylic fiber is one of the earliest developed chemical fiber species in China. Acrylic products are fluffy, warm, soft to the touch, and have good weather resistance and anti-mildew and anti-moth properties. Acrylic fiber has a wide range of applicability, but the wastewater generated during its production is a major problem facing the world. The complex composition and high toxicity of acrylic wastewater pollutants, the presence of many oligomers and other difficult to biodegrade, as well as the presence of sulfate, sulfite and other bioinhibitory components, make the biochemical properties of acrylic wastewater very low, making it very difficult to treat. In this paper, we propose an acrylic wastewater treatment method based on deep oxidation technology to solve this problem, which can effectively carry out wastewater treatment and make it meet the national discharge standards.

Published: July 2021

With the objective of improving the measure performance of Acoustic Doppler Current Profiler (ADCP) and promoting the level of marine environmental monitoring, the precision and accuracy of ADCP current measurement have been analyzed in detail based on the current flume with water concentration (0 - 20) kg/m3. The experiments indicated that the precision of ADCP current measurement is enhanced with the uprising of water concentration. The precision of ADCP measurement was significantly influenced by the water concentration when the current was (0.7-0.9) m/s, and it was less affected by the water concentration when the current was 0.3m/s. In addition, with the increase of water concentration, the accuracy of ADCP measurement increased at first and then decreased. The accuracy of current measurement was higher when the concentration was (9-11) kg/m3, and decreased in varying degrees outside this range. When the current was 1.1 m/s, the accuracy of ADCP was greatly affected by the concentration, while it was less affected by the concentration in the case that current is 0.3 m/s. The correlation analysis and conclusion can provide a reference not only for the research and development of ocean observation equipment, but also for marine scientific studies.

L’individu peut s’emparer de ces outils à notre époque, pour témoigner de son existence, et tenter d’inscrire son histoire personnelle, parfois intime, dans une histoire humaine globalisée. Dans un contexte où les images s’échangent à grande vitesse, en renseignant sans trêve toutes les crises qui agitent le monde, chaque sujet cherche à s’approprier sa propre histoire, et sa place parmi les autres. Donner un sens personnel à son existence serait aussi indispensable que complexe pour les sujets rescapés d’une histoire traumatique collective. Le travail psychique nécessaire pour y parvenir pourrait alors être soutenu par les qualités artistiques et techniques du film et par un accompagnement art-thérapique adapté. En s’appuyant sur un travail de médiation artistique réalisé avec deux jeunes femmes rescapées du Bataclan, l’auteure tente de montrer quelles sont les spécificités de la création vidéo et de son accompagnement dans le champ art-thérapique et en quoi ceux-ci favoriseraient une reconstruction personnelle.

Published: July 2021

Education is an important part of individual life. Everyone is learning whether realizing it or not. There is pressure for a longer period of formal education due to the growing volume of knowledge and the need to use it in working life nowadays. In connection with new technologies, there is a need for growing population with tertiary education, but there is also a need for a skilled workforce with appropriate vocational training achieved by upper-secondary education. Formal education takes place mainly in the full-time form, which makes it necessary to give up the possibility of earning income from classic employment relationship. Improving employability at labour market and possibility to get higher net income, forces individuals to stay at education for longer time and to sacrifice possible incomes during the time. Therefore, education is analysed as opportunity costs and the payback period of education is assessed with respect to the increase in the net mean income. The results of the analysis carried out according to data from the Member States of European Union show significant differences in the opportunity cost and in the return on education as investment, both, for tertiary education and for upper-secondary education.

While the XR technologies struggle with limitations of the proper research on one side, multiple research projects including this one, have shown significant acceptance and potential of the XR technologies, especially in the ongoing digital era accelerated by the COVID-19 situation. The research presented in this paper was held with the small groups of artists in France who had opportunity to test the augmented reality mobile application on artworks from various artists. This and other cited research projects show that the acceptance rate of the XR technologies by the informed audience strongly predominates over its penetration in such population which can be interpreted as significant market opportunity. This milieu has strong impact on the democratization of the XR industry in the recent years with substantial investments by business sector. Meanwhile these technologies have become powerful enough to raise serious concern of their impact on ethical issues, social distancing and other related topics.
