The electric grid system is the basis for functioning of the Unified electric power system of Russia and technologically isolated electric power systems. One of the most serious problems in the electric power industry is the aging of the fixed assets of already built and operating power grid facilities. The second problem is to clarify the seismic hazard of the territories of the Russian Federation in the direction of its growth. As a result, the number of power grid facilities fall into the zones of increased seismic hazard. In the zone of 7 points or more, approximately 30 % of the entire length of electric networks and transformer capacities are located. Information is provided about the characteristics of seismic load and how the objects respond to an earthquake. The experience of earthquakes testifies to the high vulnerability of the overhead power lines, cable power lines, substations, power transformers, relay protection equipment and automation under intense seismic loads. Information is provided about massive damage to the power grid during earthquakes in the territory of Russia, Armenia, and other countries of the world. Frequently occurring short circuits during earthquakes in electrical networks, at transformer substations, in electrical equipment elements of power grid facilities lead to fires. It is determined that power grid facilities have less seismic resistance than electric power generation facilities, than buildings and structures where electrical equipment is located. The problem of insufficiency of the current regulatory framework for ensuring seismic resistance of electric power facilities was also identified. Possible measures to prevent accident rate and increase the resistance, reliability, and seismic stability of power grid facilities in case of earthquakes are considered. The development of normative regulation will allow to take measures to ensure the seismic stability of power grid facilities in operation, and to ensure that control and supervision activities are carried out at a higher level.

Increasing economic importance of the Arctic, further intensification of northern sea routes, and exceptional sensitivity of the arctic natural environment to anthropogenic impacts are fundamental factors for a comprehensive study of environmental aspects in the application of innovative technologies for the development of infrastructure in the Arctic. Despite the growing interest in low-power nuclear power plants as a distributed generation facility, their possible application in technologically isolated power systems does not lose relevance. The development of both the Arctic and Far Eastern regions of the Russian Federation presents great opportunities and demand for the use of nuclear power sources. Also, development programs for the Russian arctic zone imply a significant increase in the role and number of nuclear power facilities, in other words of potential radiation-hazardous facilities. Large-scale use of nuclear-powered installations in the Arctic necessitates advanced development of a scientifically grounded and modern forecasting system as well as assessments of threats and risks in case of possible radiation emergencies at nuclear- and radiation-hazardous facilities. Also, the development of proposals for necessary measures to minimize negative consequences of such emergencies is required. This is especially true for the case of compact placement of industrial, infrastructure and residential facilities in the Arctic in the immediate vicinity of nuclear facilities. The paper demonstrates that the demand for low-power nuclear power plants and their competitiveness will grow steadily in the conditions of electric-power industry decentralization, further spread of distributed generation and the development of technologically isolated power systems. Approaches to the generation of a low nuclear-power system based on the philosophy of industrialization of production and centralized management are presented. Special features of the environmental impact assessment of low-power nuclear power plants for the development of a methodology to study the radio-ecological hazard related problems are provided.

Abstract In modern low-voltage electrical installations, the predictive maintenance of the major electrical equipments involved in the power delivery process (transformers) or in the conversion of the electrical energy (especially electric motors) becomes mandatory. Thus, a high level of reliability and safety is assured for both the electric facility and operators. The proactive maintenance is to be non-invasively performed and mainly requires an infrared (IR) thermographic inspection and power quality analysis of the installation loads. A vibration investigation is also necessary for the motor drive systems. The paper critically studies the first two main maintenance procedures revealing their main characteristics, performances and limits. A case-study presents a 1000 kVA distribution transformer that supplies a bakery facility that comprised mainly heaters and inductions motors as loads.

Solar energy is one of the main power sources of electricity in the world. It has become widespread as an attractive solution to provide low power consumption to human groups live in remote villages or areas away from the national electric grid, also when the electric power is underproduction such as in our country (Iraq). For this reasons we designed a system of photovoltaic generator with facilities to be built in houses. The system consists of three basic parts of equipment, 3KW peak solar panels, which could be spread easily at the housetop, a storage battery system and the electrical control system. The electrical control system was completely designed and tested using ORCAD simulator, it consists of 4KW battery charge regulator with 300V system, and 220V, 50Hz transformerless three – level square wave inverter.

Introduction. Over the past twenty years, the most severe natural and man-made disasters have occurred in various regions of the country and the world, as a result of which people were deprived of housing. The increase in the number, scale and duration of the consequences of emergencies related to the violation of the conditions of normal living of people requires the creation of temporary field accommodation points for the affected population, which create and serve rescue formations. At the same time, in the complex of tasks aimed at the life support of the population and rescue units in field temporary accommodation facilities, their electric power supply plays an important role. However, the established practice of calculating the electrical loads of stationary objects by methods based on data on separate electrical receivers makes it difficult to determine them for a field temporary location of people due to the lack of reliable information on its electrical receivers, which leads to significant errors in calculations, irrational composition of the electrical supply system and the use of its elements against the background of restrictions in the use of local energy resources and infrastructure facilities, which themselves may experience difficulties with reliable power supply due to the limited capacity of local power systems. The purpose of the study. Electric power supply and electric power safety of field temporary accommodation points of the affected population and rescue units, ensuring the required reliability of electric power supply, maximizing its efficiency in conditions of possible resource constraints and minimizing the influence of the uncertainty factor when planning power consumption. Research methods. The main provisions of the calculation of electrical loads, systems theory, set theory, probability theory and the apparatus of mathematical statistics. The results of the study. A methodology has been developed that allows to justify the power consumption of a temporary field accommodation facility for people, while the construction of its life support power supply system is carried out in accordance with the available consumers, taking into account their composition, area and other factors affecting the organization of the power supply system and the construction of consumers. Conclusion. The scientific and methodological approach to the choice of methods for calculating the electrical loads of the life support system of the affected population and rescue units during field deployment is substantiated, which also allows to resolve the contradiction between the need to organize the power supply of their life support and the lack of reasonable standards of power consumption of life support facilities and methods of their calculation. Key words: temporary field accommodation, life support, electric energy consumers, electric power supply, organization.

Power systems in general supply consumers with electrical energy as economically and reliably as possible. Reliable electric power systems serve customer loads without interruptions in supply voltage. Electric power generation facilities must produce enough power to meet customer demand. Electrical energy produced and delivered to customers through generation, transmission and distribution systems, constitutes one of the largest consumers markets the world over. The benefits of electric power systems are integrated into the much faster modern life in such extent that it is impossible to imagine the society without the electrical energy. The rapid growth of electric power distribution grids over the past few decades has resulted in a large increment in the number of grid lines in operation and their total length. These grid lines are exposed to faults as a result of lightning, short circuits, faulty equipment, mis-operation, human errors, overload, and aging among others. A fault implies any abnormal condition which causes a reduction in the basic insulation strength between phase conductors or phase conductors and earth, or any earthed screens surrounding the conductors. In this paper, different types of faults that affected the electric power distribution grid of selected operational districts of Electricity Company of Ghana (ECG) in the Western region of Ghana was analyzed and the results presented. Outages due to bad weather and load shedding contributed significantly to the unplanned outages that occurred in the medium voltage (MV) distribution grid. Blown fuse and loose contact faults were the major contributor to unplanned outages in the low voltage (LV) electric power distribution grid.

В настоящее время на судах и объектах морской индустрии широко внедряется энергосберегающее электрооборудование, что позволяет добиться резкого снижения расхода электроэнергии и массогабаритных показателей оборудования, существенно расширяет функциональные возможности электротехнических комплексов и систем, приводит к улучшению эксплуатационных характеристик. Однако использование новейших энергосберегающих технологий, основанных на нелинейных элементах, и коммутация электрооборудования приводит к ухудшению качества электрической энергии в судовой электроэнергетической системе. В то же время, растет число потребителей, предъявляющих к качеству электроэнергии повышенные требования. В итоге, работа судовых энергокомплексов может отличаться от расчетной, а в ряде случаев становится аварийной. В работе приведены результаты экспериментальных исследований показателей качества электрической энергии в судовой электроэнергетической системе учебного парусного судна «Крузенштерн». Представлены результаты лабораторных исследований на физической модели судовой электростанции с источниками электромагнитных помех, обоснованы организационные и технические решения по снижению уровня электромагнитных помех в судовых электроэнергетических системах. Nowadays, energy-saving electrical equipment is widely introduced on ships and maritime industry facilities. It leads to a decrease in power consumption, weight and dimensions of equipment, significantly expands the functionality of electrical complexes and systems, and provides improvement of operational characteristics. However, the use of the latest energy-saving technologies based on non-linear elements and the switching of electrical equipment leads to a deterioration in the quality of electrical energy in the ship's electric power system. At the same time, the number of consumers with increased requirements for the quality of electricity is growing. As a result, the operation of ship power complexes may differ from the normal one, and in some cases it becomes emergency. The paper presents the results of experimental studies of electric power quality indicators in the ship's electric power system of the sail training ship "Kruzenshtern". The results of laboratory studies on a physical model of a ship power plant with sources of electromagnetic interference are presented, organizational and technical solutions to reduce the level of electromagnetic interference in ship power systems are substantiated.

Electrical energy from power plants to industrial facilities and settlements is mostly transmitted by wire-connected air or underground lines covering vast territories. However, in some rare cases there is a need for wireless transmission of electrical power to objects located in hard-to-reach areas. The problem of wireless transmission of electrical energy will become especially urgent as space electric power industry based on the placement of solar power plants in outer space is being developed. In this regard, several countries are conducting studies on the problem of electrical energy transmission using both laser and microwave radiation. The fundamentals of building systems for wireless transmission of electrical energy over short distances using microwave radiation are considered. Two options for constructing such systems are analyzed and calculated: using parabolic antennas and using phased array antennas. For both options the main parameters of systems for wireless transmission of electrical energy at 200 m were calculated. In the first case, powerful microwave devices are used: a magnetron or a direct-flight klystron; in the second case, microwave powerful field-effect transistors. For the second option the summation of the powers of microwave generators by means of their mutual synchronization is proposed.

The widespread growth of electric vehicles could pose significant grid and charging infrastructure challenges, especially in areas with underdeveloped infrastructure. This has affected the ease of charging electric vehicles. In this paper, I design a power supply strategy for electric vehicle charging facilities based on wind farm power supply. In this strategy, a preliminary selection of line conductors is carried out, and several schemes are preliminarily determined. Further comparative analysis is made from the three aspects of conductor, tower type, and bus. Through the PowerWorld software, a simulation model is established for each scheme, and an optimal strategy that takes into account economy, security, and system stability is obtained (AAC 31.5 mm double split, tower A and bus 5). This can assist in the transformation of electric vehicle power supply and the construction of wind farm power supply facilities.

Introduction of technogenic physical fields including electromagnetic fields (EMF) to the environment can have an adverse impact on both humans and environment. Development of safety tools protecting against EMF impact involves studying their intensity and assessing EMF spatial extent. This paper proposes a definition of an EMF technogenic impact zone (TIZ) concept based on the instruments lower sensitivity threshold. The paper gives the results of EMF TIZ width assessment based on the measurements of EMF electric and magnetic components intensity generated by power line communication (PLC) along its 200-meter section. The EMF TIZ width was found to be homogeneous along the PLC section. It is noted that the proposed interpretation of EMF TIZ and method of its determination can be generalized for other EMF sources as well, for example, for SHF-radiation sources, tele-and radio-transmission facilities, mobile communication antennas, etc.

In the paper on the basis of the analysis of classical power schemes traction substations of railways and urban electric transport conceptual directions of development of electric networks of external power supply of traction substations in the conditions of market economy and normative requirements of the electric power industry of Ukraine are developed, which allow to provide energy saving modes of their operation. Based on system analysis of domestic and foreign traction power supply systems of railways and electric transport of large cities, the concept of their development is substantiated and proposed by increasing the supply voltage of traction substations and minimizing capacity upflows and energy losses, which provides resource and energy savings. It is suggested that the investment programs of the structures that are part of Corporation «Ukrzaliznytsia» and the municipal services be synchronized according to their technological indicators, as well as according to the criteria of energy efficiency and quality of energy supply with similar investment programs of external energy. For reduction of energy losses, it is proposed: realization of rational schedule of train movement and deep high voltage inputs with the prospect of transition to own 110 kV distribution networks, modernization and equipping of modern rolling stock electrical equipment and infrastructure of the main and perspective directions of the railways. The need to expand tram and trolleybus lines and modernize power supply devices in terms of resource conservation requires new technologies for the design, construction and operation of the facilities of municipal enterprise «Miskelektrotransservice». Such technologies have been implemented by the «DAK-Energetika» enterprise in the manufacture of modern electrical equipment of municipal enterprise «Miskelektrotransservice» TS. The most important tasks are the improvement of stationary and mobile substations and other linear facilities of traction power supply by completing functional modular blocks with modern switchgear with digital relay protection and diagnostics of traction networks; local and remote control of switchgear devices, as well as switch diagnostics and self-diagnosis. Keywords: external power supply, traction substations, electrical networks, power systems operation modes.

Abstract. We could get many helpful information and results from satellite remote sensing images and aerial images, including disaster monitoring, grid hidden danger identification, and electricity consumption management. In the recent years, novel computer vision and deep neural network have got a lot of attention in many fields because of mimicking mammalian cognitive mechanism as much as possible. With the in-depth of mammalian cognitive and motor mechanisms research, people trend to adopt these reliable and efficient methods for power grid management and maintenance.For utilizing computing resources and improving analysing efficiency flexibly, we propose an assessing and verification framework based on bio-inspired perception and understanding, which summarizes the most appropriate image scale in the electric facilities place recognition. The proposed framework consists of different scenes aerial images datasets, several electric facilities place recognition methods, and credible evaluating methods mimicking mammals. Firstly, we gather satellite remote images and aerial images of sufficient electric power facilities in the United States via Google Earth and other public datasets. Then, several typical place recognition methods are adopted to testing recognition ability of multi-scale perception results, like SAD, NetVLAD, and GIST descriptor. To get more reliable result, multi-units and multi-scenes experiments are implemented roundly. After all experiments and evaluations, we could get that the most appropriate image scale is 1000 m size and the highest recognition accuracy of electric power facilities location is 500 m. Conclusion in our article shows the recommended perception form and scale closest to human cognition in the power grid management and maintenance.

The article discusses the issues of connecting microgeneration facilities based on renewable energy sources (RES) to electric networks of low voltage (LV) 0,4 kV. This method of connection will allow the use of microgeneration facilities as network sources of energy, and at the same time unused electrical energy generated by micro-generation facilities can be supplied to a low-voltage network of 0,4 kV. Methods of simulation modeling of the processes of electrical energy distribution in the power supply system with microgeneration objects are proposed; the requirements for the power grid controller used to ensure the connection of micro-generation facilities to the low voltage network are formulated. The problems arising in connection with this are analyzed and the ways of their solution are offered. The proposed methods for the development of software and hardware solutions using modern methods of simulation of electrical energy generation and distribution based on rapid prototyping in the Matlab Simulink environment make it possible to carry out field experiments in order to simulate the processes occurring in 0,4 kV low voltage electrical networks using microgeneration objects prosumers.

This article discusses various fields where gas turbines can play a vital role. Building engines for commercial jetliners is the largest market segment for the gas turbine industry; however, it is far from being the only one. One 2015 military gas turbine program of note was the announcement of an U.S. Air Force competition for an innovative design of a small turbine engine, suitable for a medium-size drone aircraft. The electrical power gas turbine market experienced a sharp boom and bust from 2000 to 2002 because of the deregulation of many electric utilities. Since then, however, the electric power gas turbine market has shown a steady increase, right up to present times. Coal-fired plants now supply less than 5 percent of the electrical load, having been largely replaced by new natural gas-fired gas turbine power plants. Working in tandem with renewable energy power facilities, the new fleet of gas turbines is expected to provide reliable, on-demand electrical power at a reasonable cost.

The article outlines the technology of managing electric and thermal power-engineering facilities using intelligent cyberphysical systems, implemented by remote monitoring of operated facilities and based on the ability to assess the technical condition of each equipment item (introducing risk-oriented management based on digital technologies). The technology includes coupled digital solutions that allow to quickly assess and predict the condition of the power system by comparing individual assessment data of the technical condition of the main technological equipment of electric and thermal power-engineering facilities with digital counterparts of technological processes, physical systems, objects and products for the implementation of integrated risk-oriented asset management system (AMS). The analysis identifies indicators characterizing the solution to the problem of finding optimized values under fuzzy conditions and limitations, with an integral indicator of equipment (equipment group) determined by the minimum value with respect to assessing the technical condition of each item of equipment in a single unified digital network model. Based on the introduction of a virtual model for tracking the equipment life cycle, integrated with adaptive shells of applied digital business services, the management of both technological and economic business processes is being built to switch from planned preventive repair of equipment of electric and power-engineering facilities to state-based repair.

One of the basic problems of electric power systems is the absence of normative documents regulating the operation, maintenance and repair of the capital equipment, the service life of which exceeds the normative value. We shall name them «old equipment» (OE). The essence of the difficulties to be overcome is reduced to the absence of methodologies for quantitative estimation of operational reliability and safety of OE, with the subsequent comparative analysis of OE. Considering the science intensity, cumbersomeness and labour intensity of solving this problem, the necessity of development of the relevant automated systems becomes indisputable. In this article, some features are considered of an estimation of an integral indicator and comparative analysis of unique facilities. Here, unique facilities mean those, which have no analogues in terms of the set combination of varieties of significant attributes. The methodological foundations of the synthesis of integral indicators are considered: ensuring the infallibility of the information base; requirements to evaluations of integral indicators; providing the physical essence of the integral indicator; possible types of integral indicators; the comparison of integral indicators of operational efficiency in the framework of the theory of testing statistical hypotheses for one-dimensional random variables is associated with a high risk of erroneous decisions; the assessment of the critical values of the integral indicator is carried out on the basis of simulation modeling within the framework of the fiducial approach.The development of automated systems for collecting and formalizing data on the technical condition of OE, the automated analysis and synthesis of these data, performing standardization of TEI, evaluating integral indicators and some results of comparative analysis, preparing operational recommendations to improve work efficiency, developing appropriate methodological guidelines, indicate the possibility of an objective assessment of the operational efficiency of OE and a decrease in the risk of unacceptable consequences. For an illustration of recommended methods and algorithms, technical and economic parameters of power units with SGI-400 are used.
