Authors: Shakirov Vladislav , Kurbatsky Victor , Tomin Nikita , Guliyev Huseyngulu
Published: December 2020

The article deals with the problem of the negative impact of wind farms stochastic generation on power grid. One of the ways to reduce the stochasticity of the wind farms generation is their geographically distributed siting. A technique for sizing and distributed siting of wind farms from the standpoint of the influence on the variability of the total generated power is proposed. Modeling of wind power generation with hourly detailing is carried out using the developed Wind-MCA software based on data from archives of long-term observations of ground-based weather stations. The optimal distribution of wind turbines in potential locations is based on a genetic algorithm. The objective function is the coefficient of variation of the power generated by all wind farms in the sites under consideration, depending on the number of wind turbines in their composition. The genetic algorithm is implemented using the built-in MATLAB function. The proposed technique is applied to assess the capacity options and sites for wind farms in the Zabaykalsky Krai. The solution providing the minimum value of the coefficient of variation of the wind farms generated power and high value of the wind farms capacity utilization factor has been obtained.

Authors: Madrakhimov Daniyar Bakhtiyarovich , Ivanova Vera Pavlovna , Tsypkina Victoria Vyacheslavovna
Published: December 2020

Reliability of cable lines in hot climate is determined by the climatic characteristics of cables and wires, which include: long-term and short-term heat resistance, cold resistance, moisture resistance, resistance to cyclic exposure to temperatures and solar radiation, ozone resistance, etc. This article considers the main impacts of environmental factors: high temperatures, solar radiation, which, as practice shows, lead to irreversible deterioration of the electrical and mechanical properties of cable products. The result of climatic impacts in the Central Asian region, in hot climate conditions, is the aging of both insulation and protective coverings, which leads to irreversible change in the mechanical and electrical properties of the used polymers due to the loss of elasticity of the extruded material and its subsequent cracking, turning into cracks. The assessment of the possibility of long-term operation of the used polymer was carried out according to the polyethylene oxidation period, which determines the time of natural preservation of various types of cables during the period of their operation. The research was carried out on samples of cables stored under a canopy in wooden boxes, protected from sunlight and precipitation, by measuring criterion parameters with strict compliance with the established norms. Thus, the proposed solution for increasing the reliability of cable lines consists of debugging the technological process of applying insulation and sheathing, in which the extrusion of the polymer mass is carried out by technique that minimizes the ingress of contamination. Review of the results showed that extrusion line improvement would provide possibility of increasing reliability in the operation of cable products under the impact of climatic factors of the Central Asian region due to the reduced aging of insulation.
Improving the reliability of power supply to active consumers by improving the technology for manufacturing cable product
Authors: Ivanova Vera Pavlovna , Tsypkina Victoria Vyacheslavovna
Published: December 2020

The growing demand for high-quality transmission of electrical energy with a high level of reliability of cable lines is determined not only by the conditions of operation, installation, but also by the technology of cable production. This article discusses the issues of increasing the reliability of power supply to active consumers, which is achieved through the use of cable products with a higher level of reliability. The concept of "reliability", disclosed in the article, is valid for all cables and wires with insulation, which must maintain integrity as part of the product for the entire period of operation. The use of fundamentally improved technological processes, as the conducted study shows, makes it possible to reduce ohmic resistance of the conductive part of the cable product and thereby allows reducing the temperature parameters of the operating cable line. Cable failure, in most cases, is associated with insulation breakdown, the reason for which can be caused by a rise in temperature inside the cable insulation. In this regard, the creation of conditions for reducing the ohmic resistance of a current-carrying conductor is one of the ways to increase the reliability of a cable product at the stage of its manufacture. Proposed technical solution, considered in this article, is focused on the technological operation - drawing, where changes in the standard drawing route make possible reduction of the ohmic resistance of the current-carrying conductor by 3-5% for copper and aluminum, respectively.

Published: December 2020

Pre-trial detention of persons accused of committing a criminal offense is an integral measure in the justice system of any state. In most countries, there are specialized institutions for maintenance of this category of citizens. In Russia, they are called pre-trial detention centers. Such institutions belong to the penitentiary systems. By isolating a potential offender, pre-trial detention centers perform several tasks: 1) exclude the possibility of persons to hide from the investigation and the court; 2) make it impossible for them to continue criminal activities; 3) maximally complicate their obstruction of establishment of truth in a criminal case. Implementation of these tasks is facilitated to the maximum extent by proper design and construction of pre-trial detention centers, competent placement of facilities, security buildings and premises, optimal use of special gratings, doors and locks. The article deals with the regulation of design and construction standards of pre-trial detention centers by Russian legislation. The authors analyze the experience of penitentiary systems of foreign states, as well as the norms in force in Russia, highlighting strengths and weaknesses. The actual double subordination is established in solving the current problem. On the one hand, the department executing the preliminary report, on the other, the department organizing and controlling design and construction of institutions executing preventive measure. Such inconsistency creates problems in practical application of provisions of existing norms, leads to errors and, as a result, inadequate performance of isolation of suspects and accused of committing crimes. Based on the results of the study, it was proposed to create a unified legal document regulating the procedure for design and construction of pre-trial detention centers. There is a need to exclude the listed issues from provisions of documents not related to design and construction sphere. This will provide proper, common understanding of existing problems and their faster resolution.
Urban water bodies as the basis for functioning of public spaces
Authors: Kurochkina Valentina
Published: December 2020

Recently, housing construction in cities has been carried out at a high rate. Increasingly, urban abandoned and flooded depressive spaces near water bodies (often rivers), which were previously used as industrial facilities or temporarily used, are becoming the sphere of architectural and landscape transformations. The restoration of such territories helps to improve the quality of urban space and improve its ecological properties. Correct development of territories near rivers and various water bodies has a great health-improving effect on the urban environment, improves its natural and climatic conditions. In addition, social and economic factors play an important role in this process, since such transformed territories and territories adjacent to them significantly increase investment attractiveness. This paper examines modern approaches to the development of urban public spaces, based on the formation of architectural environments that ensure the relationship of urban development with water bodies and adjacent territories. The paper notes that water bodies are not only an important component of the natural-ecological framework, but are also the basis for the framework of urban-planning natural-technogenic systems as a whole. And the creation of a continuous urban fabric is impossible without the organization of a ‘water’ line of development, provision of compositional, functional and communication interconnection of open urban and water spaces, which is actively being introduced today in architectural and urban planning practice. The paper examines the role of water bodies in the ecological system of the city, as well as in its structure as a whole. The aim of the study is to identify the features of the formation of a public urban space, to determine the patterns of its development, to identify criteria that reflect the nature, scale and features of the impact of urbanization on a water body. Some principles of revitalization of coastal areas, as well as the creation of a system of publicly accessible, compositionally expressive spaces are considered. The principles of space transformation aimed at the formation of a holistic image of the city, as well as the impact of such a spatial arrangement of urban and water bodies on the safety and quality of the urban environment are considered.

Authors: Simankina Tatyana , Lukinov Vitaly , Davydov Denis
Published: December 2020

The paper discusses the main prerequisites for the development of parking lots. The main problems are estimated, the solution of which is the construction of multi-level intercept parking lots. The urgency of the problem is associated with the increasing gas pollution in the city, an increase in the number of accidents, a decrease in the speed of delivery of goods and the availability of parking spaces in the city center. The parking lot is considered, which provides its functions all year round regardless of weather conditions. At the same time, design solutions and materials were selected to minimize financial costs. The use of steel as the main material for supporting structures makes it possible to reduce the cost of construction. Structural columns, vertical ties and beams are made from it. Floor slabs should be made of reinforced concrete on fixed formwork from galvanized corrugated sheet of various grades. When using sheets with a high corrugation, it is possible to create a ceiling without secondary beams. Staircases, stairways and elevator shafts should also be made from reinforced concrete or from concrete blocks in order to achieve the required fire resistance limit corresponding to that required for parking lot. The appearance of the multi-level intercept parking lot meets modern aesthetic requirements and also has a positive effect on the minds of motorists, appearing as part of a comfortable living environment.

Despite the fact that activities of authorized persons in during urgent investigative actions are episodic, the absence of responsibility for successful completion of investigation is unacceptable. In this case, law enforcement agencies are fulfilling a single socially important goal, and this should be realized by the relevant officials. Regarding the dynamics of accumulation of information during the investigation of a crime, it should be noted that during urgent investigative actions, an initial array of evidentiary information is formed, which is the result of transformation of initial background knowledge of relevant official regarding what happened under the influence of information obtained by investigative and operational means. The Criminal Procedure Law contains requirements both for the mechanical accumulation of a certain amount of evidence highlighting certain circumstances included in the subject of proof, and for their compliance with strictly established requirements. We are talking about the reliability, sufficiency, relevance and admissibility of evidence, which actually determine the possibility of ultimately using this information in deciding whether a person is guilty or innocent of committing a crime. The required amount of evidence that meets the requirements of reliability and sufficiency ensures the reliability of the evidence base in a criminal case. The evidence obtained should be assessed in the aggregate on the basis of the inner conviction of the person carrying out urgent investigative actions. Their use in the production of further investigation, in the course of court proceedings, depends on how procedurally correct evidence will be collected by the bodies of inquiry during the production of urgent investigative actions.
