The research indicates open-flame arc self-quenching conditions in 35 kV overhead distribution networks with low single phase-to-ground fault currents (less than 6 A): in an isolated neutral network and in a compensated network, taking into consideration arc extinction constraints for the channel modeling. The methodology stated (evidence from this 35 kV network studies) allows to analyze self-quenching conditions in case of overhead line faults. Transient single phase-to-ground faults such as direct lightning strikes, induced overvoltages due to a close lightning discharge, self-extinguishing faults entailed by incidents of mechanical origin can be considered. The analysis can be an integral part of the network reliability assessment, for instance, to calculate number of line cut-offs with fast or automatic reclosing.

In this paper a novel impedance control technique is developed. The technique is aimed to suppress the steady-state ripples of a micro grid's DC-bus voltage, caused by load's current harmonics. The effect is achieved by lowering the bus impedance at the selected frequencies, that correspond to the frequency spectrum of the loads. The frequency-selective impedance control (FSIC) is implemented by increase of the voltage-loop gain at the specified frequencies using the cascade of the resonance-type controllers (R-controllers). The R-controllers are tuned to the parameters of the distortion. Since the oscillation frequency of the R-controller isn't restricted by the voltage-loop's bandwidth, the control capabilities of a power converter are extended up to its Nyquist frequency. An approach to configure the R-controllers is developed. The effectiveness of the technique is proved by the experiments at the DC micro grid prototype. The experiments demonstrate a significant reduction of the bus voltage ripples under the FSIC.

In this paper we have studied the software system of the semi-physical simulation training system for wind turbines, along with the optimizing of yawing and power distribution for offshore wind turbines considering long-term fatigue loading. The semi-physical simulation platform is based on doubly-fed wind turbines. The semi-physics terms refers to the need for usage of actual physical objects or controllers in the simulation system. One of the most vulnerable modes for the load affecting is yawing process. Since the yawing errors may strongly affect the strength loading, the study of mechanical and electrical, as well as fatigue properties, is very important. To reduce maintenance frequency, we proposed an optimized power distribution for balancing fatigue differences between wind turbines, and adopted the consistency algorithm in the multi-agent system (MAS), using the fatigue value of the wind turbine as the consistency variable to solve the problems with different fatigue values.

The problem of determining locations of a double ground fault in networks with isolated neutral is much more complicated due to a topographic remoteness of faults places. The necessary level of perfection of the novel method for determining locations of such faults is ensured through the use of many algorithmic network models. The general algorithmic model of the network is used to calculate the voltage at the supposed place of a fault. Algorithmic models of an undamaged network and models of a pure fault regime allow dividing electrical quantities into components, related only to the measured voltages at the installation location of the device, and into components that are completely determined by the fault currents. Such property of the models allows the algorithm to be theoretically independent of short circuit resistances. An important role in fault locations is played by the hypothesis of the resistivity of the ground fault circuit. Following this idea, the new algorithm uses an objective function to fault location on the line, which is a measure of the transmitted reactive power in the transverse circuit between phase and ground. The stability and accuracy of the algorithm do not depend on the remoteness of faults places from each other.

The last decade has seen increased interest of Russian manufacturers in distributed generation (DG), as it can produce cheaper energy for less costly and more competitive manufacturing. In some cases, critical users that cannot afford power outages have to construct hydrocarbon-fired DG facilities. This paper analyzes the electric parameters of power districts that contain distributed energy sources (DES) and how those parameters change in a variety of operating situations. It has been found that fast electromechanical transients might cause the power quality to vary significantly, and short-term fluctuations in the parameters to occur in a wide dynamic range, especially in case of islanding. The paper considers the core factors that necessitate changes in the requirements to relay protection and automation systems (RPA) shall DES's be integrated in distribution grids on a large scale. The authors here of present their guidelines on how to tackle various issues when projecting the development of, or operating distribution grids.

One of the possible promising directions for the development of relay protection technologies today is the development of a digital centralized relay protection and automation system (RPA). Due to the current state of development of modern information technologies and the emergence of new international standards, IEC 61970 and IEC 61968, additional opportunities have appeared for solving the problems of automation and control of power facilities, creating a digital type substation. A digital substation is an electric grid with a monitoring, protection and control system, and is based on the transmission of information in a digital format. The aim of the article is to develop a software package designed to diagnose a centralized relay protection system, which is one of the main elements of such a system. The structure of the software package is developed in the article, the data of the diagnostic system for the centralized relay protection system are described and grouped, its configuration is presented, and the problems of relay protection configuration are considered. Recommendations are given on setting up the relay protection and automation functions based on the analysis of their operation with the help of algorithms for determining the location of damage and reference algorithms. The algorithm of the digital diagnostic system of the centralized relay protection system is described and the data flow diagram of the digital diagnostic system of the centralized relay protection system is described. Currently, the software package is undergoing a testing phase and is in trial operation.

The paper is concerned with the features of the PLC-technology and describes the common circuit solutions of data communication devices along power lines. The research group proposes an original type of a data communication device based on making use of new physical phenomena, which have never been applied in the PLC-technology before. An inverted magnetoelectric effect in multidimensional composition material is used to transmit a signal; this effect is a combination of the piezomagnetic and the piezoelectric effects connected by elastic interactions. The proposed data communication device does not have either a transformer or a galvanic coupling between the power high-voltage line and the low-voltage information lines, thus eliminating the influence of the high operating voltage of the power line on the low-voltage lines of high-frequency equipment. The proposed variant of the data communication device can be easily incorporated into standard high-frequency equipment, thus providing higher quality level of its operation. The developed data communication device was tested by experiment as part of an experimental security and fire alarm system.

Traction networks (TN) 25 kV generate higher electromagnetic fields (EMF) with frequency 50 Hz, whose strengths at a standardized height of 1.8 m, as a rule, do not exceed the permissible norms for electrical personnel. In places where railroads routes intersect with high voltage overhead power supply lines (OPL), interference of fields, generated by the traction network and OPL, occurs. This can lead to an increase in strengths and a complication of the EMF spatial structures. The article presents simulation results performed for a complex intersection, while 25 or $2times 25$ kV TN is crossed by a three-circuit 110 - 220 kV overhead power line at 90 degrees angle. Fazonord software application was used for simulating EMF strengths in points of traction networks and OPL intersection. Based on modeling results the following conclusions have been made: at intersection points of $1times 25$ kV traction network with a three-chain 110 - 220 kV power transmission line, the electrical field strength does not exceed the value acceptable for electrical personnel and reaches 4.2 kV/m; at the intersection with $2times 25$ kV traction network, this parameter decreases to 2.7 kV/m; the maximum amplitude of the magnetic field at the intersection points increases slightly.

A typical power supply scheme of an oil pumping station is considered. Also, the influence of short electrical disturbances (voltage dips and interruptions) on the dynamic stability of synchronous and asynchronous motors of an oil pumping station is considered. It is shown that to ensure the stability of power supply of oil pumping station, to reduce losses with various types of short circuits and the presence of closed networks in the power system, we can use fast automatic transfer switch (FATS) device. Such FATS devices should have special current direction relay, response time to emergency mode less than 9 ms and work from external protections of power supply system. Based on the calculation studies, the requirements for the BAVR device are determined.

The paper discusses the research of the cylindrical linear AC electronic motor control system for the actuating mechanism of direct material application. The design of a linear electric motor is considered. A functional control scheme of a rotary linear valve motor is presented. The basic parameters and equations necessary for use in the motor control algorithm are considered. The control of the CLEM module is carried out using a converter in the frequency range (0.5 ÷ 6) Hz to obtain the necessary high-speed motion of the actuating mechanism. The motor control is based on a PC. The software is implemented in C + in the Microsoft Visual Studio 2010 environment and is focused on use on an industrial or personal computer. The personal computer is connected to the frequency converter via a cable communication line of the RS-485 standard (using the RS-485 / USB interface converter) based on the ModBus protocol. Experimental researches of the electro-drive module of the CLEM have shown that the developed system allows to operate in the required speed range within (0.03-0.36) m/s. At the same time, the movement of the secondary element in one direction is 1.2 m, and the number of binary moves varies from 0.75 to 9 per minute. The nominal force of the CLEM module is 400 kN. Algorithm of control tested on experimental installation. The system fully satisfies the characteristics of the technical task.
