POWER QUALITY
The tasks of scientific and technical policy in the field of power quality at the present stage of digital economy development in the Russian Federation
Abstract.
Power quality assurance should be viewed as an independent cross-sectoral task in the light of large-scale digitization of the branches of national economy and modernization of generating and electric grid companies equipment. The paper considers the special features of the existing approach for power quality management taking into account sectoral development trends. The impact of approaches to power quality indexes calculation on the production processes of individual industrial enterprises and relationships between consumers and suppliers is analyzed. Practical steps for scientifically based solution of power quality problems are proposed.

Standardization and conformity assessment of power quality
Abstract.
The paper considers the issues of power quality assurance for consumers in the Russian Federation, with the use of standardization and conformity assessment mechanisms. The general analysis of the current legal acts and reference documentation in the field of power quality standardization and conformity assessment is given. The main problems of regulatory activity implementation in the field of power quality in Russia are shown and solutions of these problems are suggested.
Keywords:
standard, standardization, conformity assessment, certification, electric power
Ensuring power quality and power supply reliability for a large industrial enterprise
Abstract.
The paper considers the problems of ensuring power quality and power supply reliability related to insufficiently developed design solutions (the example of a large industrial enterprise is considered). Technical measures and means for eliminating the shortcomings of power supply scheme are proposed. The effectiveness of those means is demonstrated using mathematical modeling tools.
ENERGY EFFICIENCY
44 Electricity consumption forecasting. Practice of application
Migranov M.M., Ustinov A.A., Melnikov A.V.
Abstract.
Current trends in the development of the electric power market in the Russian Federation are characterized by: aconstant increase in the prices of resources that are needed for the fuel and energy complex for the continuous production of electricity; rise in the cost of the construction of new power plants and power grids for energy transportation; widespread rise in insolvency of enterprises-consumers of electricity. The reform of RAO “UES of Russia” in 2008 led all participants of the wholesale electricity and power market to the need to develop their own unique strategies and tools for using energy resources to ensure a balance between the energy produced and consumed. In this article, we compare the various methods for predicting electricity consumption using machine learning algorithms and statistical methods using the example of the forecast of the electric power consumption for own needs of the 500kV SS Chelyabinsk PJSC “FSK UES”

OVERHEAD TRANSMISSION LINES
58 Joint oscillations calculation of conductors and transmission poles within section of an overhead transmission line under the action of periodic wind load
Kravchenko A.Ya., Krasnorutskiy D.A., Levin V.E., Rodenko S.V.
Abstract.
The paper presents the results of joint oscillations calculations for conductors and transmission poles of power transmission line section with P110-3 poles. Transmission poles are represented by reduced finite element models with preservation of internal dynamics in the range of several lower eigenfrequencies and are included in the nonlinear dynamics of framework which is simulated conductors, insulator strings and ground wire. After calculating the response of the system to lateral wind load, the displacement amplitudes are applied to the full-size finite element pole model and stress distribution throughout the pole is determined.

Abstract.
The paper presents first developed methodological basis for determining the acid number by means of rapid method. In order to increase the reliability of acid number semi-quantification through rapid method, the application of the recommendation model based on naive Bayes classifier via use of the corresponding indicators in the RGB system is demonstrated.

FIRE SAFETY
116 Fire hazard of cable lines in plastic pipes laid in the ground
Smelkov G.I., Ryabikov A.I., Pekhotikov V.A., Nazarov A.A., Kuznetsova E.V.
Abstract.
The paper considers the selection of plastic pipes (mainly polyethylene pipes) for purpose of cable laying and wire installation. Previously published articles recommend to select pipes on the ground of thermophysical and mechanical properties of materials used for pipes manufacture. In addition to those publications, the paper considers new dimension of the problem — cables fire protection inside the pipe.

128 Analysis of advisability of arc breakdown detectors for integrated protection from fires caused by failures of electrical equipment
Korolev I.V., Kondratieva O.E., Valuev P.V, LoktionovO.A.
Abstract.
Analysis of fires, arising during the operation of electrical installations, shows that one of the main causes of their occurrence is the electric arc. Herewith, the majority of the classic protection means does not prevent the ignition of cables in this case. The article presents an overview of foreign experience in the development of the regulatory framework and technical solutions for detecting arc breakdown and increasing the efficiency of protecting electrical networks from fires. A comparative analysis of arc-breakdown detection devices on the Russian market is carried out.

Abstract.
The modern stage of civilization development is characterized by the increasing of power-to-weight ratio and therefore by the expansion of the circle of persons, linked with exploitation of various electrical installations. In these terms, health and safety issues in the exploitation of electrical equipment gain specific value. In this article the review and systemization of basic demands about maintenance safe work under voltage and analyze of demands regarding safety at various schemes of carrying out such works are represented. Basic ways of increasing safety works in grids under voltage are suggested, including of accounting for the influence of atmospheric conditions on work outside.
