Evaluation of the Efficiency of Electrical Systems when Using a Multi-Stage Capacitor-Reactor Voltage and Reactive Power Regulator
Tabarov B.D. (Komsomolsk-on-Amur State University)
Abstract. Ensuring the normal operation of electrical equipment and maintaining its service life, increasing the capacity of the transmission line and reducing electricity losses, as well as improving the technical and economic performance of an electrical installation depends on the efficiency of electrical systems in the transmission, distribution and consumption of electricity. To evaluate the above indicators, the article examines the efficiency of existing electrical systems with traditional and new multi-stage capacitor-reactor voltage and reactive power regulators, which are based on mechanical devices and power electronics components. The purpose of the work is to evaluate the efficiency of electrical systems with known and proposed technical solutions for the transmission, distribution and consumption of electricity. To achieve this goal, the methods of automatic control and simulation modeling were used in the work. The MATLAB Simulink software package was used as a simulation tool. The results obtained from a study of the efficiency of electrical systems with existing and proposed devices in the event of a voltage deviation in the supply network within ±16% and a change in load current ranging from —95% to +117% of the nominal level are presented. The field of application of the obtained research results is electrical engineering systems, where the transmission of electricity over a long distance is considered. The most appropriate field of application of the research results is electrical engineering systems, where continuous and joint regulation of voltage and reactive power is required over wide ranges and ranges with high accuracy. Comparative analyses of the research results have shown that the use of a new technical solution in a real installation makes it possible to improve the efficiency of electrical systems despite the deviation (fl uctuation) of voltage in the supply network and (or) load current in wide ranges.
Keywords: power supply network, electrical system, main step-down substation, harmonic voltage coefficient, current curve distortion coefficient, multi-stage capacitor-reactor voltage and reactive power regulator.

Feasibility Study of the Impact of Regulatory Obstacles on the Investment Potential of the Solar Microgeneration in Russia
Kharitonov M.S., Kugucheva D.K. (Kaliningrad State Technical Univesity)
Abstract. The article presents the comprehensible feasibility study of regulatory obstacles that inhibit the development of solar microgeneration in Russia. Based on the detailed hourly simulation modeling of the energy balance with regard to climate conditions, technical parameters of solar power plants and stochastic features of the household power consumption, the quantitative assessment of the impact of key regulatory factors on the pay back term of microgeneration facilities was performed for four different regions. It was stated that in the present-day conditions (high cost of the process connection of microgeneration facilities and sales of excess energy for the price calculated by the wholesale market figures) the pay back term is between 8 to 19 years. Therefore, the projects are investment-inattractive. With the help of the sensitivity study it was shown that the dominant system obstacle is the asymmetrical tariff policy. It was shown that introduction of the excess energy sales by the retail tariff is the key measure to be taken to reduce the pay back term and stimulate the development of this energy sector.
Keywords: microgeneration facilities, renewable energy sources, solar power, pay back term, regulatory obstacles, tariff policy.

Determination of the State of the Insulation System of Electrical Equipment (Method of Reference Curves)
Chernyshev V.A., Serebryannikov S.S., Zinchenko K.A., Pevtsova L.S. (Branch of the National Research University MPEI in Smolensk)
Abstract. The desire to ensure reliable operation of power equipment in a given time interval runs into the need to solve the problem associated with assessing the state of a controlled electrical device. However, the lack of a reliable control parameter, a stable comparison base, and convenient hardware design of the measurement method does not allow monitoring the condition properly. The paper describes a method for integral assessment of the state of an insulation system of an energy device based on a spectrum of dielectric absorption currents. The peculiarity of the disclosed method lies in using as a state control parameter not separate points of dependence of total polarisation current on time in a given time interval, but the entire dependence i(t) as a whole, while eliminating loss of useful information. Although it is not possible to avoid some difficulties in forming a set of reference curves (as a stable comparison base), the proposed method makes it possible to organize quite reliable control over the condition of the equipment in operation.
Keywords: diagnostics of the insulation system, spectrum, dielectric absorption currents, technical condition index and health index, state assessment methods, matrix of regression equation coefficients.

Abstract. High-voltage circuit breakers are among the most critical components of power systems, the reliability of which largely determines the uninterruptible power supply to consumers. Failures of oil circuit breakers that have reached the end of their rated service life pose a particular danger. This paper examines the main causes of high-voltage oil circuit breaker failure.
Keywords: high-voltage oil circuit breakers, equipment aging, rated service life, emergency shutdowns, automatic reclosing (AR), transformer oil, insulation degradation, diagnostics, sludge.

Earth Fault Area Detection in a MV Overhead Transmission Line

Abstract. A method for localizing the zone of single-phase ground faults in networks with ineffectively grounded neutral (high-resistance resistor, arc-suppression reactor, or isolated neutral) is presented. The method is based on the excitation of high-frequency oscillations in RCL-sensors. The amplitude of these oscillations is determined by the steepness of the voltage wavefront and decreases significantly with increasing distance from the fault location. Analysis of the voltages on the sensor capacitors, obtained via telemetry, is performed using a low-order interpolation polynomial, the maximum of which indicates the fault zone. It has been established that non-equidistant placement of sensors on an overhead line increases the determination error, whereas increased ground resistance has a relatively minor effect on the accuracy of zone localization.
Keywords: overhead power line, single phase ground fault, RCL-sensor, linear measurement device, fault location, transient process.

Galeev R.G. (Novosibirsk State Technical University)
Abstract. The use of high-temperature superconducting windings in power transformers is one of the promising areas in the electric power industry. The paper presents an analysis of electromagnetic processes in a transformer with a spatial magnetic system to assess its effect on the distribution of the transformer’s magnetic field and the stability of the superconducting state. To optimize the calculations, it is proposed to use the method developed by the authors for calculating power transformers with low-voltage windings made of high-temperature superconductors based on classical approaches to transformer design. The method is implemented in the Python programming language and confirmed by comparing it with the parameters of a real prototype transformer. The results demonstrate high calculation accuracy, which confirms the adequacy of the proposed mathematical tool and the possibility of its use for designing transformer equipment combining a hybrid design of superconducting windings and a spatial magnetic system. Liquid nitrogen was used as the dielectric medium of such a transformer (temperature —196.7°, 77 K). In addition, the effectiveness of the infl uence of the spatial magnetic system on the stability of the superconducting state of the HTS winding has been proven.
Keywords: high-temperature superconductivity (HTS), transformer, magnitude of the critical current of a superconductor, spatial magnetic system, frequency of alternating current, hybrid windings.
