The existing control systems for compensating installations do not take into account the general state of the power grid in terms of reactive power flows. The article proposes the monitoring system that processes data from a current and voltage sensor in a distribution grid, based on the processed data control actions are formed on corrective devices. Today high-speed static VAR compensators (SVC), built on the principle of indirect compensation, are most widely used. However, such compensators have a number of disadvantages, therefore, to improve the energy efficiency of the monitoring system, it is advisable to use SVC based on magnetic valve elements. To predict reactive power in the distribution grid, the artificial neural networks (ANN) module is used in the monitoring structure. To train the neural network, using the method of combined matrices, a distribution grid model is formed.The proposed monitoring system will make it possible to stabilize the parameters of the grid for consumers, to reduce losses from reactive power flows. The neural network module included in the main processor will reduce the development of emergency situations. The use of SVC based on magnetic valve elements will increase the energy efficiency of the monitoring system in distribution grids with a sharply variable nature of electricity consumption.

This paper presents a description and appearance of a software package that implements the possibility of conducting researches of cascades with an arbitrary hydrological scheme. The complex allows to make water-energy calculations of HPP cascades, HPPs under construction and upgraded. Using the complex, can be determined the energy effect, i.e., increase in generation, of HPP cascade due to the construction of a new plant or the modernization of an existing one. The complex is developed in the Python programming language using the PyQt5 library, the calculations are optimized using the dynamic programming method. The calculation is made for the stage of pre-project assessment of the feasibility of building a hydroelectric power plant. The data for calculations were taken for the Kama hydroelectric power plant.

Modern car security systems are complex, multiprocessor systems in which the main module interacts with peripheral devices via digital buses. One such device is a microprocessor-based shock sensor. The sensing element of the sensor is usually a MEMS accelerometer. To distinguish between weak and strong impacts on the car body, the sensors have two zones (two levels) of operation. Publications on shock sensors are mainly advertising in nature. This is due to production secrets and unwillingness to disclose signal processing algorithms. The paper presents experimental data on accelerations upon impact on a car body. An information signal processing algorithm is proposed that excludes false alarms and allows the implementation of a digital sensor with 16 adjustable sensitivity gradations and adaptation to periodic disturbing influences.

Technologies for energy saving and use of renewable energy sources are in great demand today. Application of turboexpander units allows to cover a wide range of technological needs, including the use of secondary energy resources. In the course of the work the design features of turboexpander units used for utilization of excess pressure of natural gas at gas distribution stations during pressure reduction in the gas pipeline, as well as units for utilization of low-potential heat of flue gases and other gaseous heat carriers are considered. The potentially more efficient scheme of the flue gas utilization installation, based on the use of energy of the gas flow through the gas utilization non-compressor turbine with a parallel heat recovery is proposed. On the basis of technical and economic calculations of the presented installations and a comparison of their design and technological features, the effectiveness of their use has been evaluated. On the basis of the results obtained the most rational designs of utilization plants, based on the use of turbo expander units were selected.

Digital signal processing is widely used in modern technology, including robotics, medical technology, etc. Thus, high-pass filters are used to eliminate the constant component of the output signal at the output of an analog-to-digital converter. This also reduces the low-frequency interference level spread out on the frequency axis to the left of the lower boundary of the signal spectrum. In the case of a dynamic change in the signal and interference spectra, controlled digital filters are used, the coefficients of which explicitly depend on the cutoff frequency. A non-negative impulse response, which corresponds to a flat transient response, is required. For example, in the case of determining the presence of a negative signal against the background of a positive pulse of a much larger amplitude. Or, conversely, to determine the presence of a positive signal against the background of a negative pulse. As this takes place, a signal pass is allowed, but a false detection is not allowed. False detection can be caused by undershoot or fluctuations in the step response ($SR$) of the high-pass filter. The paper investigates the structures of high-pass filters based on a parallel connection of a direct pass and a cascade connection of first order low-pass filters, which are obtained by the method of invariant transformation of the impulse response. The disadvantage of some of the studied structures is the presence of an overshoot on the amplitude-frequency response in the vicinity of the cutoff frequency. The conditions under which the negative impact of this emission decreases, are analyzed.

The article is devoted to the analysis of existing models of magnetic fields formed by magnetostrictive converters of linear and angular displacements containing permanent magnets in the form of a rectangular parallelepiped. Mathematical models of permanent magnets in the form of a rectangular parallelepiped are considered. It is shown that not all existing mathematical models allow to correctly and accurately calculate the magnetic fields of permanent magnets in the form of a rectangular parallelepiped. Computational experiments were carried out to study the magnetic field of permanent magnets in the form of a rectangular parallelepiped using mathematical models. The results of computational experiments also showed that the difference in the calculations of the magnetic field strength of magnetostrictive displacement transducers containing permanent magnets in the form of a rectangular parallelepiped according to the exact model and the approximate model differ and depend on the ratio of its length or length and width from its thickness. Depending on whether this value exceeds 10 times, it becomes possible or not to use the above formulas and expressions. It is revealed which formulas and expressions are better to use in this or that case. To confirm the results of the computational experiment and theoretical studies, an experimental test was carried out, which showed a coincidence with the results obtained in computational experiments.
