The large-scale adoption of renewable energy throughout the world is only increasing. In terms of economic efficiency, large photovoltaic (PV) installations are only slightly inferior wind power plants, which makes solar energy an attractive energy resource, not only for the construction of solar power stations, but also for installing solar panels in households. In this paper, the authors address the urgent problem of clean solar energy. This paper presents the results of a study of the selection of an engine, an electric drive for it and the software environment of an autonomous and reliable device for cleaning solar panels. The main advantages and disadvantages of solar panel cleaning systems are considered. A system characterized by low power consumption and the absence of the possibility of panel shading, was ultimately designed. To date, a sample has been assembled that can clean the SDM-50 panel from snow, dirt, sand and other contaminants.

To ensure systematic and effective solutions to maintaining fixed plant assets in constant operability and preventing equipment depreciation, they carry out appropriate maintenance and repair. This paper presents an analysis of the ways of organizing maintenance and repair of utilities’ high-voltage equipment as a possible tool for extending its lifetime. Within this study, such methods of organizing maintenance and repair, as time to failure, preventive maintenance and on-condition repairs were considered, as well as approaches to their selection and justification at various electric power enterprises. Also, within this study, the authors made an analysis of implementing energy enterprise management based on plant assets management systems as decision support systems, where the model of equipment maintenance and repair is the basis for its implementation. This paper discusses the use of the equipment technical condition index, which solves the problem of extending the equipment service life in ensuring its required reliability.

The wide use of distributed generation (DG) technologies in electrical energy systems (EES) requires development of new control algorithms in normal, emergency and post-emergency modes. The issues of determining the static aperiodic stability margin in EES equipped with DG plants are of particular relevance. These plants can be removed from the consumption centers, which can lead to static aperiodic stability reserves depletion. The article presents the results of studies aimed at the developing static aperiodic stability reserves express calculation methods in EES equipped with DG plants. An effective technique to determine stability margins was proposed based on one of the modifications of limiting modes equations. The results of determining static aperiodic stability for an electrical network with distributed generation plants are presented. Additionally, the simulation of transient processes in the studied EES for various points in the space of the mode’s controlled parameters has been carried out in the Matlab system.

Automobile engines are the main source of harmful emissions into the atmosphere in large cities. These engines use gasoline or diesel fuel. The efforts of many scientists are aimed at developing measures to reduce the impact of gasoline engines on the environmental situation. Conversion of gasoline engines to gaseous fuel (methane) is considered in this article as an effective way to improve the environmental performance of automobile engines. An overview of research on this topic is given. The article provides a description of the technical characteristics for two gasoline engines that are converted to work on methane. The study was carried out on the basis of mathematical modeling of the engine operating cycle in the Diesel-RK program. A brief description of the mathematical model is presented. It is shown that the conversion of gasoline engines to methane leads to a decrease in power within 7.5% while simultaneously reducing the specific fuel consumption by up to 12%, and there is also a decrease in NOx emissions by 2-3 times. It has been established that the compression ratio of a methane engine has a significant impact on the technical and economic indicators. It was revealed that an increase in the compression ratio to 15 leads to an increase in the power of the gas piston engine to the level of a gasoline engine. At the same time, fuel consumption is reduced by up to 20%, and improved environmental performance is observed in comparison with a gasoline engine.

Nowadays active power refers to the power quality parameters. That’s why, measurement of active power parameters is required in power quality measuring instruments. This paper describes a technique for active power measurement which apply a discrete Fourier transform of instantaneous power. The conveniences and drawbacks of this measurement method are considered in comparison with the accumulation of instantaneous power method and the application of low-pass filtration method. Analytical expressions are obtained that make it possible to estimate the active power measurement error caused by “spectrum leakage” effect for one-harmonic and polyharmonic measured signals situations. Approaches to reducing the methodological measurement error without significant changes of the original measurement algorithm are considered. Methods for decreasing the active power measurement error as a result of finite frequency deviation are proposed. The metrological and implementation features of discrete Fourier transform implementation for solving problem are considered. The simulation model is performed by the implementation of the Goertzel algorithm. With the application of a simulation model, performed by Simulink package, the accuracy and credibility of the obtained analytical formulas are estimated.

Intelligent auto-reclosing technology is an effective method for mitigation of switching overvoltages that occur during reclosing of power lines with shunt reactors. The idea of this technology is to precision control the moment when the power line is energized to reduce the intensity of electromagnetic transients that induce overvoltages. In this paper, we consider the application features of the theory of intelligent auto-reclosing of long transmission lines with shunt reactors in a three-phase auto-reclosing cycle. The principles of choosing line phases energizing moments are investigated and the optimal strategy of three-phase intelligent auto-reclosing is proposed. In contrast to the known strategy, the new strategy takes into account both the inter-phase coupling effect and the influence of the spread of circuit breaker operation time on. The modeling proved better efficiency of the new strategy compared with a known strategy of intelligent auto-reclosing and significant advantages over traditional metal-oxide surge arresters, even if a spread of circuit breaker operation time exists.

This research is focused on the integration of Ethernet POWERLINK (EPL) fieldbus with the Robotic Operating System (ROS) for real-time control tasks. In this part, we analyze latencies and jitter introduced by the Linux operating system, ROS and the openPOWERLINK stack. To increase the determinism of the operating system, we propose using the PREEMPT_RT patch from OSADL. To ensure the simplicity of process data exchange, we offer software that implements the openPOWERLINK stack with a standard ROS interface for applications running with a cycle time of more than 10 ms, and a specialized API based on the POSIX infrastructure for high-speed applications with a cycle of 10 ms or less. The introduced concept covers both Managing (MN) and Controlled (CN) nodes, making it possible to easily integrate Ethernet POWERLINK communication in any robotic application task. More details about hardware and software implementation issues will be described in the paper dedicated to the second part of this research.

Nowadays, the algorithms of the windowed digital signal processing are widely used for the development and introduction of the phasor measurement units. The specific feature of these algorithms is the presence of spikes at the beginning of the transient process due to the inclusion of both steady-state and transient processes into a window span. As a result, the error of the electric mode parameters acquisition during the data accumulation period rises. This effect can be mitigated by shifting the window to points after the beginning of the transient process. In this paper, we present an effective algorithm for real-time determination of the inception point of the transient process. The algorithm was tested on model-generated and real signal samples. The criterion is suggested for precision enhancement of the algorithm by utilizing beginning points of transient processes of phased and linear voltages and phased currents. The error of prediction for the real samples testing does not exceed 0.001 seconds.
