Published: August 2020

Abstract
This work is devoted to the urgent issue of the analysis of arc surges in electric networks of the Arctic region of the Russian Federation, using the electric power system of the Kola Peninsula as an example. The article presents an approach to the development of a computational model of a power system in the Matlab software environment, the Simulink simulation application. When compiling the calculation model, the following points were taken into account: the model was in a three-phase formulation; the inductances of overhead power lines were taken into account; non-linear arc resistance was taken into account; grounding resistance was taken into account; the magnetic coupling between the phases and interphase capacitances were taken into account. Based on the results of the model, graphs of transients in the system were obtained for various operating modes. The correctness of the calculation model was checked on the following points: on the voltage, it is necessary that the phase voltages on the buses of the substation ΦC-24 correspond to the phase voltages at all points of the model and be shifted relative to each other by an angle of 120 °; current, current at all points of the system, the current must be symmetrical; according to the current of a single-phase short circuit, it is necessary that the value of the short circuit current obtained using the calculation model corresponds to the current value obtained in the analytical calculations. In the study of arc surges, more than 60 calculations were performed. The performed calculations showed the dependence of the overvoltage ratio on the fault location and the uneven distribution of overvoltages in the considered sections. An analysis of the results obtained in the work allows us to conclude that it is advisable to apply this approach to other electric power systems of the regions of the Russian Federation and other countries.

Published: August 2020

Abstract
The problem of heat supply to remote dispersed consumers of the Arctic and the possibility of such a local renewable energy source as wind to be involved in are considered. The wind potency distribution over the western sector of the Russian Arctic is shown. Areas with enhanced wind potency are identified, which are the most promising ones for heating needs. Wind energy cadastre principal characteristics of the region are studied (average longterm wind speeds, seasonal distribution in average monthly speeds, wind speed frequency, etc.). There is a winter wind speed peak in coastal areas, which coincides with the cold season peak demand for heating power and electricity. This is the main prerequisite for the successful joint operation of current boiler rooms with wind power plants (WPP), which are able to provide a significant part of the heating load. It is shown that the use of wind energy will save (displace) a significant amount of expensive imported fuel and significantly reduce the working cost of heat generated. The climatic characteristics of the region are studied, and the values of reduced (taking into account the wind) outdoor temperature are estimated. The way how the wind strains the initial picture of the distribution of average annual air temperatures is shown. The consumer heating-load curve and its provision by WPPs possible participation and boiler rooms are considered. The share of high wind potency WPPs reaches 60-80% in one year.

Published: August 2020

Abstract
Geological interpretation of formation processes of Precambrian assemblages with a complicated structure (reconstruction of geodynamic formation settings of metamorphic rocks protoliths) requires approaches other than those applied in studying Phanerozoic objects. The current paper reports some new approaches to studying the material composition and geodynamic evolution of early Precambrian complexes. They are based on the authors’ techniques of identifying the original nature of metamorphites, statistic modeling of varied features of chemical compositions of Precambrian objects in regard to standards of geodynamic settings in the Phanerozoic and considering them in geodynamic reconstructions.
The use of digital technology when positioning the spreader relative to the plane of the container

Published: August 2020

Abstract
Currently, the technological process for processing containers in the presence of a roll or trim of the vessel involves the participation of working personnel. This technological operation is poorly automated, so the spreader is positioned relative to the plane of the container with the help of people, which increases the load cycle, reducing effective and economic indicators. The development of microprocessor technology allows us to automate partially or fully technological processes of container reloading in the port. The most important part of the container handling process is the spreader. Existing systems of automation of the spreader allow detecting gaps between containers, which increases the accuracy of installing the container at the storage location. The developed experimental model offers the option of automating the positioning of the spreader relative to the plane of the container, complementing existing automation systems, such as vibration dampers, sensors for monitoring the position of the container, etc. Using an experimental model allows to reduce the processing time of the vessel, and also eliminates operator errors. The issue of ensuring the operability of electronic components and sensors in the Arctic climate is also important, as they are most exposed to the environment. When using electrical equipment at low temperatures, there are two main problems: safety and operation. The functionality of electrical equipment may change or deteriorate, and the failure of one of the electrical systems entails stopping the loading cycle until it is detected and fully fix the problem. Therefore, in this paper, we consider possible options for preventing the negative consequences that arise when working at low temperatures.

Abstract
Personnel potential plays the key role in the effective development of the Russian sector of the Arctic. It is impossible to conduct the study of the personnel potential without reliance on the psychological science. This article discusses the phenomenon of personal success and its relationship with the model of vital activity chosen by a person. According to the results of the empirical study the publication presents the factor structure of the value-semantic and emotional-volitional characteristics of the personal success in students with different models of vital activity (vital, social and existential). The factor analysis carried out by the method of principal components with varimax-rotation showed that respondents with an ideal of vital model of vital activity (3 factors were highlighted) have pragmatic orientations - “high level of income”, “personal prestige”. Such manifestations as “spiritual satisfaction”, “creativity”, “self-development” get evaluation below average. The factor structure is dominated by indicators that reveal a disharmonious state, a low level of adaptability to people around them and changing situations. Respondents with an ideal of social model of vital activity (4 factors were identified in total) are oriented towards cooperation in professional and social spheres. They demonstrate high level of social adaptability and a tendency toward self-development and express self-efficiency. Respondents with an ideal of existential model of vital activity (3 factors are highlighted) choose the following priority areas: professional activities, training and education, public life. They are characterized by prosocial behavior, a manifestation of altruism and a desire to contribute to socially significant projects. At the same time, they express harmonious state and are prone to assist people around. The information presented in the article has practical value for teachers, students and graduates of higher schools, HR managers.

Diversity of regional trends in traditional reindeer husbandry in the Russian Arctic
Authors: Klokov K B 
Published: August 2020

Abstract
Domesticated reindeer livestock is an important resource for traditional economy of the indigenous peoples of the Russian Arctic. The article analyses the variability of the reindeer number trends in different Arctic regions and the reasons why reindeer livestock increases in some areas and decreases in others. The analysis is based on the official statistics data and scientific literature. Author argues that the key condition for the success of traditional reindeer husbandry is the informal economic environment. Due to peculiarities of the regional politics and the ways of adaptation of indigenous communities, such environment have been formed only in four municipal districts in the tundra of Western Siberia. In all other territory of the Russian Arctic the number of domesticated reindeer decreases or fluctuates at about the same level.

Published: August 2020

AbstractDespite developed regulatory framework enshrining legal status of indigenous small-numbered peoples and governmental law-enforcement practice, challenges appear in implementing rights of such population category. One of factors jeopardizing realization of Arctic indigenous peoples rights is interest of companies and states in Arctic resources development. A set of conditions from an increasing geopolitical and economic interests of states in Arctic resources development to challenges of sustainable development of the Arctic region leads to the need for states to negotiate and conclude a treaty with mechanisms for protecting Arctic indigenous peoples rights. The States parties to the 1982 UNCLOS, including Arctic states and indigenous representatives, are recommended to be involved in its elaboration. The Arctic states bear a special responsibility to ensure Arctic indigenous peoples rights. Such treaty should stipulate an obligation of each Arctic state to take the views of indigenous representatives in regulating legal relations with their participation. While the Artic resources development by resource companies is a factor posing a threat to protection of Arctic indigenous populations rights, activities of companies involve new jobs creation and social infrastructure development. The treaty should stipulate a mechanism for a balance between the interests of Arctic indigenous peoples and resource-extracting businesses.
Current state of sympatric whitefish from Lake Pyaozero, Kovda river basin, Karelia
Authors: Sendek D S , Bochkarev N A , Savosin D S , Borisovskaya A A , Ilmast N V 
Published: August 2020

Abstract
The study of whitefish from Pyaozero Lake (White Sea basin) has shown that three forms of sympatric whitefish occurring in the lake are abundant. They clearly differ from each other, but the existing forms/species are similar in countable characters. The evolution of modern White Sea basin populations is associated with the postglacial colonization and hybridization of several genetically distant whitefish forms, This factor is assumed to have given rise to populations with various morphological and ecological characteristics, e.g. growth rate and maturation time. The fact that haplotypes in the morpho-ecological groups of whitefish are highly mixed is consistent with the heterogeneity of the haplotypes revealed earlier in Kamennoye Lake, Kem River basin. Analysis of a gene of ND1 mtDNA has shown that two major phylogenetic whitefish lineages, from which Pyaozero whitefish has derived, are of European origin, while the third one is closely related to whitefish from Siberian water bodies. The strong hybridization of ancestral phylogenetic whitefish lineages in the recent forms of Pyaozero whitefish is also indicated by evidence for the genetic variability of allozymic loci. Recent paleolimnological reconstructions suggest that the origin of multi-rakered whitefish from Karelia’s lakes is associated with the postglacial colonization of an old multi-rakered whitefish lineage, whose relict populations have preserved in the old lakes of the White Sea-Kuloy Plateau unaffected by Lower Quaternary glaciation.

Published: August 2020

Abstract
The complex task of man-machine control of weakly formalized technological units and complexes, which are characterized by a wide variety of conditions, multidimensionality, non-stationarity, uncertainty, multivariate products, is considered. The insufficient effectiveness of the model approach to creating control systems for such objects is shown. Alternative approaches based on the concept of best practices are considered. The well-known best practice procedures using typical representative situations and the model cycle method are presented. A new (precedent) method for the selection and implementation of control actions with the participation of an operator-technologist is proposed. A precedent cycle for selecting controls and a functional diagram of the control system have been developed. An information model of the precedent is formed on the example of steelmaking control in an oxygen converter. The advantages of the precedent method compared with the method of representative situations are determined.

Authors: Ostrovlyanchik V Yu , Popolzin I Yu 
Published: August 2020

Abstract
Using of a doubly-fed machine circuit is a promising way to upgrade existing electric drives of hoist installations based on wound-rotor induction motors. Power connection of induction motors according to the scheme of a doubly-fed machine with control of machine coordinates in the rotor circuit allows to increase the energy efficiency of the drive, organize the recovery of energy, which is usually uselessly dissipated in the rotor circuit, as well as increase the reliability of the drive. To achieve a wide range of speed change while maintaining the overload capacity of the machine by the torque, it is necessary to combine various methods for controlling the amplitude, phase and frequency of the auxiliary voltage on the rotor. These parameters are controlled by a logical control system. So it is necessary to develop an operational algorithm of the logical control system to organize this way of control. This paper is devoted to the development of the operational algorithm of the logical control system for the electric drive of a lifting installation based on a doubly-fedinduction machine, which allows combining different modes of operation of the machine to achieve a wide range of speed control.
