Energy industry is traditionally considered as the one with the high requirements towards safety and reliability as integral components of the sustainable functioning of the entire country’s industrial complex. The article analyzes the risk assessment methods, the use of which is most appropriate in the framework of industrial safety management system to prevent and minimize damage from accidents at energy facilities. The proposed algorithm for assessing the risk of accidents at energy facilities, based on the Failure Mode and Effects Analysis (FMEA), Event Tree Analysis (ETA) and Human Reliability Assessment (HRA) methods, will increase the level monitoring effectiveness of repair work organization of electrical equipment and its technical condition.

This paper studies the application of the distributed static synchronous series compensator DSSSC in the power flow control of 110 kV transmission system. The transformer-less DSSSC is developed to control the injected series voltage to regulate the power flow. The power electronics circuitry and control system of such compensator are developed and analyzed. The control system for power flow regulation is designed to provide fast and stable response at various modes of operation. The power flow control using the DSSSC is applied for two power system models; the two-machine model and the two parallel transmission line. The practical implementation and practical results emphasis the ability of the proposed compensator to control the injected voltage to control the power flow throw the transmission lines.

Currently, the repair and maintenance of overhead lines is necessary to ensure uninterrupted power supply. Analysis of the statistics of electrical injuries shows that accidents during this type of work make up the majority. One of the reasons is the effect of induced voltage on disconnected lines passing near active lines. When the overhead lines are grounded only at the workplace, the electrostatic component is completely removed, but accidents occur during such work.When calculating the capacitive current for three-phase lines, it is necessary to take into account the increase in the number of wires, the phase shift of currents in the influencing line and partial capacitances. The calculation of induced voltages is carried out for symmetric modes of network operation. In practice, it is necessary to take into account the asymmetry at different loads at energy enterprises. It is shown that the asymmetry increases the value of the induced voltage.

The paper presents a software product that enables contactless identity verification at various sites using Leap Motion controller and neural network module, which will improve security at critical sites. The authors present the results of a study of numerical sequence generation for identification through two-factor authentication and a predictive hand model recognition module to perform automatic identification of an individual. The process of verification of an identifiable fingerprint is based on a decision support system–by means of a fuzzy rule base, the percentage coefficient of accessibility for an identifiable person is determined. In addition, the algorithm has been optimised to work with devices based on ARM single board computers-the deployment is in this case an independent customer authorisation unit at a remote distance from the information processing server with the varied possibility of working offline and online modes.

Currently, batteries are of great importance in the modern life of every person. With the development of electronics, there is an increasing number of portable equipment, therefore, there is a need of compact portable devices. Batteries are widely used as power sources for Autonomous vehicles. Whatever system the batteries are applied for, its premature failure can lead to consequences of varying severity. This article will discuss the processes that affect battery wear, as well as recommendations for reducing the negative impact on battery wear will be given.

Electrical node centrality for the power networks is an essential parameter to identify the critical nodes under attack. Topological analysis is vital for evaluating the network robustness while electrical characteristics have to be considered to make the analysis consistent for realistic power networks. However, the capacity limit of the power network changes under various nodal attacks. It is essential to find the relationship between the loading margin limit of the power network with the node centrality features, so that appropriate measures can be considered to improve the robustness of the power networks. Thus, voltage stability index (VSI) is defined for every node, and its centrality features are modelled. Robust Bayesian regression is used to model the nodes responsible for a change in loading margin and causing grid blackout. The method has been validated on benchmark complex power networks like reduced Great Britain network, IEEE 57-bus and IEEE 118-bus systems.

Energy storage elements based on lithium-ion batteries became a part of new generation of power systems. One of the most efficient places of energy storage elements implementation is DC traction system because of train regenerative breaking mode. The experiment made in 2012 in Moscow metro shows advantages of energy storage elements installation at 2 substations even at the worst conditions for regenerative breaking. Authors extended that experiment to digital simulation to show the potential advantages of energy saving in ideal conditions. Authors considered two different locations of energy storage element. The first location is DC bus of the first substation. The second location is the point in the middle between the first and the second substations. The results show the significant advantages of its connection to the point in the middle between substations and provides better operation conditions.

In this paper, a comparative study has been performed between two methods used to detect short circuits in stator winding. The first approach is based on the motor current signature analysis (MCSA), while the second approach is based on the analysis of the negative sequence component (NSC). The study showed the advantages and disadvantages of each method, and it also showed the change in the fault indicator for each method under different operating loads and in the presence of short circuit in the stator winding. Experimental results proved that MCSA is more efficient to detect short circuits in the stator winding.

The article presents the results of the development of a mathematical model for assessing the technical condition of boiler installations based on generalized experimental data on failures due to damage to superheaters and evaporation surfaces, depending on the thermal load. Based on the results of the analysis, it was found that statistical data on operating time, failure rate, metal condition, and residual resource allow us to develop approaches to evaluating the performance of each equipment element in order to obtain a reliable and representative sample of failure statistics for assessing the reliability of components and systems of boiler plants. The results obtained can be used to create predictive models that provide approaches to prolonging the operation and operation of elements of boiler plants and in the implementation of projects of digital energy systems for monitoring and diagnostics of power equipment of thermal power plants.
