The problem considered in the work is concerned to detecting of signal distortions occurred in the railway ALSN cab signaling system. The ALSN system is designed to transmit track status information into the train cab and uses rails as a continuous communication channel between track and train. The amplitude and duration of the pulses in the ALSN code combinations are changed over time due to deterioration of the track transmitters and other devices in the signal transmission channel, as well as due to electromagnetic influence of the traction current, rails magnetization, and other sources of electromagnetic interference. Due to distortions of ALSN signals, their decoding becomes unstable, which leads to intermittent failures in the form of temporary incorrect indication at the cab traffic light or to complete failure of the ALSN system. Diagnostic of the ALSN system and the revealing of signals with distortions is carried out by analyzing the signal current, recorded using the railway car-laboratory. However, the use for this purpose of the classifiers with sharp boundaries for input diagnostic parameters and strict rules for signal selection does not allow us to reveal incipient defects that arise in the ALSN system. The work investigates the effectiveness of using adaptive neuro-fuzzy inference system (ANFIS) and wavelet packet energy Shannon entropy (WPESE) for timely detecting of signal distortions in the ALSN system. The obtained results confirmed the efficiency of ALSN signal processing using ANFIS and WPESE for detecting of railway sections with unstable or faulty ALSN system.

In this paper, a technical virtual power plant (TVPP) aggregates distributed energy resources (DERs) under its supervision to participates in energy and flexibility markets. The paper presents a two-stage co-optimization framework which in the first stage, the TVPP participates in day-ahead (DA) energy market and specifies the optimal scheduling of the DERs and in the second stage, the TVPP participates in real-time (RT) flexibility market and specifies flexible DERs’ optimal upward and downward flexibility powers. The TVPP aims at maximizing its profit while taking distribution network operational constraints and the customers’ preferences into account. Furthermore, the uncertainties associated with the DERs are considered using scenario-based stochastic approach. The proposed model is mathematically formulated as a mixed integer linear programming (MILP) which guarantees obtaining the global optimum solution. The model is implemented on the IEEE RBTS-BUS5 distribution test system and the obtained results demonstrate the effectiveness of the model.

In our day the use of Lithium ion battery has considerably increased, especially to feed light electrical vehicle (LEV) application. These types of batteries need careful attention to avoid deep discharge and overcharge. Therefore, a battery management system is mandatory for the real-time monitoring of their main parameters i.e state of charge (SoC) and state of health (SoH). On the other hand, since these batteries have chemical structure, they need careful modeling of their internal reaction, some methods use electrical battery modeling. This paper proposes an advanced model of battery pack suitable for the estimation of SoC and SoH. It allows the emulation of electrical parameters’ variation such as the Open Circuit Voltage (OCV) model as well as the thermal effect and balancing process. Simulation results are given and compared to former research works to emphasize the completeness of the proposed model.

One of the effective use areas of an active rectifier is AC drives based on autonomous voltage inverters. In them, an active rectifier makes it possible to recuperate the energy of the electric motor into the supply network and increase the electromagnetic compatibility of the converter with the supply network. This can be achieved by using various topologies of active rectifier control systems. Therefore, in this article, an analysis of the basic control systems effectiveness of an active rectifier was carried out in the implementation of the main functions assigned to the converter power circuit. A new structure of a vector control system with a fixed modulation frequency is proposed, which makes it possible to form a sinusoidal mains current with a given phase shift relative to the supply voltage.

The paper is devoted to development of technology and equipment for obtaining of protective reinforcing and heat-shielding thin-film coatings with controlled structure and their usage in production of tools with improved operating characteristics in technological engineering. Recent times much of attention has been paid to creating of wear-resistant hardening coatings and development of multilayer nanosized coatings. By changing the application parameters of such coatings, one can control the composition, particle size, morphology as well as thickness and number of individual layers. Due to this, they can be easily adapted to obtain optimal physical and mechanical properties. The most effective method for coating of cutting tools is ion-plasma vacuum-arc coating deposition (Arc-PVD) which is characterized by high deposition rate and high ionization degree of the vaporized material providing increased adhesion strength of a coating, and this is the main objective of the article.

The light-absorbing coatings based on low-vacuum aluminum condensates are alternative to existing light-absorbing coatings. Such coatings obtained by special methods of metal condensation in low vacuum have extremely high absorption factor (As > 95 %) in the visible and infrared spectral regions makes optical properties of these coatings similar to black body properties. It was investigated the morphology and optical properties transformation of such coatings after one-year exposure to open space simulator. The effect of substructure and optical characteristics stability of inorganic light-absorbing thermoregulatory coatings based on low-vacuum aluminum condensate at thicknesses t > 0.3 μ and the size effect associated with substructure and optical properties degradation of coatings at small thicknesses (t < 0.2 μ) were found.

In this work, a smart temperature monitoring system was developed for a Parabolic Solar Thermal Collector (PSTC) integrated with Membrane Distillation (MD) system. The objectives of this work were to monitor and record the temperature data of salt solution in the PSTC system and to control the circulating water pump flow based on the targeted temperature. The PSTC system was used as a supporting system to pre-heat the salt solution until the it reaches the desired temperature. This was monitored by a DS18B20 waterproof temperature sensor. The real-time data was then be displayed on an LCD, saved in a microSD card and via smart phone. An Internet of Thing (IoT) of Blynk Applications and data logging systems were utilized. The energy and the separation performance of the integrated system was also investigated. The highest temperature attained by the PSTC system based on the conducted experiments was above 60°C. Based on the results, a fluctuation of energy consumption by the integrated system was observed. This was due to the supplementary energy supplied by the solar collector system. The integrated system also exhibited a moderate separation efficiency with maximum permeate flux of 3.5083 kg/m2.h and salt rejection of 93.96%. As a conclusion, the PSTC system integrated with MD system can surely bring a lot of benefits for the desalination industry. Additionally, IoT can be employed in the future as means to accurately monitor solution temperature for such integrated systems.

Modern requirements for traction DC power supply in the organization of high-speed movement are reduced to the need to provide a normalized voltage level of 2900 V on the pantograph of electric locomotives. The existing power supply system does not allow to provide the necessary mode of voltage at change of load and the necessary specific energy consumption, despite the considerable aggregate power of traction substations. The purpose of the work is to develop a hybrid traction system with the use of alternative generators of electricity. The article presents the algorithm of interaction of different types of generation when the traction load is changed. The developed hybrid power supply system for electric rolling stock allows to provide the necessary voltage level on electric locomotive pantograph and to reduce the range of its changes, which will allow to fulfill the necessary conditions for ensuring high- speed movement without changing the voltage in the traction line.
