The instrumental control of the charging balance makes it possible to quickly assess the efficiency and technical condition of the components of the vehicle power supply system. Factors have been developed that allow assessing the technical condition of the automobile alternator (efficiency factor) and its operation efficiency at the current combination of load and engine speed. The main parameters of the power supply system were measured using a four-channel analog data logger. Further research will be aimed at identifying the changes in the charging balance of the vehicle in case of failures of the automotive alternator and accumulator starting battery.

This chapter proposes the interpretation of the concept of “power supply system efficiency” and a mathematical model that focuses on minimization of electricity supply expenses while observing the time criteria. The research examines the constituents of the specified time criteria, the calculations of power outage time, and the time of power supply restoration. In addition, this chapter describes the constituents of implementation time for a technological connection of rural consumers to electric networks and the statistical data on the time of inconsistency between power quality and regulatory requirements. Furthermore, this chapter investigates the applying possibility of the proposed mathematical model for the development of measures that can improve power supply system efficiency. In order to improve electricity supply reliability of rural consumers, the technical condition monitoring of power lines and electrical network automation is carried out.

Abstract The paper considers the implementation prospects and features of the synthesis of an intelligent automatic system for diagnosing the internal combustion engine vibration of a power supply system in terms of developing technologies for automatic or remote control of unmanned vessels. The paper addresses the issue of predicting the technical condition of a combustion engine using available diagnostic methods. The study focuses on the equipment required for monitoring and analyzing the technical condition of the engine of an unmanned vessel when operating in automatic or remotely controlled mode. An algorithm has been developed for collecting, storing and accumulating data on the condition of the engine components and units in the on-board information system of the vessel to exchange data on the condition of the engine and its components during remote monitoring and to determine fault codes. The approaches to the synthesis of an intelligent automatic system for diagnosing the combustion engine vibration are considered from a methodological point of view. Vibration diagnostics equipment used for the analysis of the technical condition of the engine is proposed. Some results of the classification of the technical condition of the engine are presented. The expediency of introducing and using hybrid intelligent systems based on artificial neural networks is exemplified by diagnostics of the MITSUBISHI S16R engine.

The article is devoted to choosing ways to improve the technological reliability of regional electric network (REN) to ensure reliable power supply. At the operational stage, the task of increasing operational reliability is assigned to the enterprise asset management system of the territorial network organization (TNO), as a REN operator. Technological reliability is ensured by an operational dispatch control system, which uses the existing reserves in the network to support the technological process of electricity supply to electricity consumers in case of network equipment failures. The relevance of improving the technological and operational reliability of power supply system (PSS) requires the development and improvement of methods for analyzing and assessing the TNO's readiness to provide power transmission services. The indicators adopted in Russia reflect the level of technological reliability of PSS. However, these indicators do not reflect the technical condition of the equipment, or identify causal relationship between an equipment failure and an interruption of power supply. The research is aimed at identifying “bottlenecks” from the technological reliability standpoint and substantiating maintenance and repair, and technical re-equipment and reconstruction measures to improve operational reliability. A PSS model is proposed reflecting the technical condition of the network equipment, the operational readiness of automation systems, the availability of structural, functional and load redundancy in the REN. A method is suggested for calculating the PSS reliability indicators, where the developed indices reflect the degree of development of the network technical potential and the role of the aforesaid nodes in the PSS. The method makes it possible to identify the network parts, where it is necessary to introduce new technologies. In contrast to a well-known method, which is based on expert estimates of probabilities of different circuit-mode states of the network and on the calculation of normal and post-emergency modes, a less timeconsuming formalized procedure for analyzing and evaluating the network structural and functional reliability is proposed. The results obtained allow to increase the validity of the decisions made both at the operational stage and the design stage.

Abstract This article describes the methods and means for determining the technical condition of electrical equipment in power supply systems, particularly in transformer substations. There are many ways to determine the technical condition of electrical equipment. However, their implementation requires complex and additional equipment and devices. In addition, these tests must be carried out when the power supply system is off. This will lead to a decrease in the quality of electrical energy. Determination of the technical condition of electrical equipment using thermal imagers is performed under the voltage and in operating modes, the measurement process does not affect the parameters of the power supply system. The results of research in energy enterprises of the Syrdarya region are presented.

The paper analyzes damage along overhead and cable power lines. The calculation of the main indicators of reliability is carried out to predict the value of the actual resource of the main high-voltage electrical equipment for the shops of the production metallurgical line. The calculations were performed for the existing circuit using the software package [1]. The performed analysis of the obtained results of the developed algorithm and methods for calculating reliability indicators made it possible to assess the technical condition of overhead and cable lines subject to intense aging in terms of voltage levels and to estimate the number of outages at nodal substations.

Units of modern cars require an uninterrupted supply of electricity of the required quality, therefore, the prompt determination of the technical condition of the power supply system (SE) is an urgent task. During the operation of the car, there is a dynamic redistribution of electricity consumed for the needs of consumers between the car generator and the storage battery (AKB). The efficiency of the balance of electricity on board the car is influenced not only by the power of consumers, the mode of movement of the car, weather and climatic factors, but also by the technical condition of the generator and battery, however, insufficient attention has been paid to this. It has been established that the currents of the generator, the field winding and the battery, as well as the voltage of the on-board network, can serve as indicators of the technical condition of the vehicle’s ESS. The purpose of the article is to develop typical loading modes of a vehicle’s solar cell and a technique for their modeling in laboratory conditions. The leading method for solving this problem is fixing the ESS parameters using an analog data recorder with variations in the load current and the generator rotor speed. In the course of the experiment, the loading modes were changed in the order of increasing the generator rotor speed. The nature of the change in the parameters of the solar cell in the case of a working generator and a charged battery has been determined. The efficiency of the solar cell can be indirectly estimated by the ratio of the areas limited by the charging and discharging currents of the battery of the dynamic characteristic curve. With a load current of 10 A, the energy supplied by the battery generator exceeds the energy consumed for the work of consumers. When the load current increases to 15 A, the energy balance shifts towards the discharge part. The experimentally established dependences of the change in the parameters of the solar cell with variations in the load and speed modes of operation can be considered a scientific novelty. The practical significance of the research carried out is to increase the reliability of diagnosing SE based on the analysis of indicators of its technical condition. Further research will be aimed at determining changes in the parameters of the vehicle’s ESS in the process of occurrence and development of generator and battery malfunctions.
