In view of the fact that excessive illumination levels are economically and hygienically unprofitable, it is necessary to use LED lights with adjustable brightness. As LEDs are DC devices, a pulse width modulation (PWM) may be effectively used; it enables variations of LEDs current and luminous characteristics within a wide range. The method of brightness control with PWM for LED sources featuring a moderate inertia generates an enormous pulsation of luminous flux imperceptible to humans but adversely affecting human health. Given a low inertia of LED sources becomes evident, inertial properties of human vision must be considered. When designing a safe lighting system, processes of fast and slow adaptation at perception of flickering light should be taken into account. For that purpose, a mathematical model complying with basic laws of physiological optics and reflecting vision perception of flashing light was developed. Estimate of vision inertial properties proved the need for increase of PWM frequency at luminous flux control.

Regulation of the transformation ratio maintains a standard level of transformer substation voltages within power distribution networks. At the same time, the problem of power loss minimization within the rated period taking into account an appropriate selection of automatic regulator's transformation ratio is solved. The paper proposes an algorithm for power loss minimization under average load conditions of network operation. The equivalent T-shaped network design is used. Voltage level of transformer substations is controlled by calculating the maximum and minimum load limits. A distinctive feature of the algorithm is maintaining an optimal power loss in view of network process limitations.

The article examines the issues of digital signal processing high-performance computing structures development for solving problems of plastic piping diagnosing in the system of oil fields' reservoir pressure maintenance. Pipelines diagnostics is based on the magnetic field changes study in the pipe damage areas. This method allows fault detecting from the earth's surface without resorting to expensive procedures of pipes excavation. Having the aim to obtain reliable information about the magnetic field condition, we propose a modular wavelet analysis by using polyphase filters with finite impulse response. It is proved that transition from the normal radix numeration system to the deductions system based on the Chinese remainder theorem in the filtering process significantly contributes to the pipelines digital data processing performance.

The population of thermostatically controlled loads can be used to solve power balance control tasks in electrical grids. Nowadays, effective use of resources and improvement of electricity production is a very important issue, thus, research studying the use of smart grid features are topical. The first paper part deals with simulation of the population of thermostatically controlled loads. The proposed method is quite convenient and effective. It allows us working with a large group of electrical heaters. The second part of the paper contains an example of the task which can be worked out. The obtained results show that the task can be solved relatively well even using some simple controller structure such as the PID-controller.

The paper considers the method for measurement of active and inductive resistances of the power line supplying career excavators based on mathematical processing of current and voltage at the input of the excavator in two modes of operation — power consumption and power recuperation during the excavation cycle. Parameters of measurement errors when using the line transducers of different class index numbers have been estimated. The effectiveness of the method has been confirmed by simulation of an excavator electrical system practical use of the developed module for controlling parameters of power line as a part of the information-diagnostic system designed for career excavators.

The study focuses on the investigation small-signal stability in power systems using two methods. One of the methods is traditional method of modal analysis investigating behavior of the eigenvalues. Another one is a new sub-Gramians method that was worked out in Institute of Control Sciences (ICS) RAS. The method is based on the application of the so-called sub-Gramians derivable from solving the Lyapunov equations. The comparison of methods was made using the MATLAB software for two test systems: 1) a well-known model of transmission system proposed by P. Kundur, and 2) IEEE 57-bus test model.

The analysis conducted is of influence of unmeasured and measured (process mode parameters) feature variables, such as catalyst activity, feed data on the model parameters is conducted. It is shown that at the change of the unmeasured feature variable the situation models with linear structure can be adjusted by means of absolute polynomial term change for oil refining and petrochemistry processes. The conditions and algorithm of adjustment of linear situation calculation models of technical and economic values considered during normal facility operation is suggested.

We propose a new system for control of an electric drive of the cutter-loader greatly improving its operational reliability and safety. The problem is solved by forecast of electric and mechanical diagnostic indicators of the electric drive and implementation of predictive control activities related to maintenance and repair based on actual technical conditions. Forecasting drive parameters is enabled with a neural network model. It increases the mean time between failures and availability factor of the electric drive compared with operation of the control system without a parameter prediction feature.

The mathematical model of the experimental stand for vibration damping is described in the article. A vibration table is used as a source of vibration of different frequencies. Asynchronous motors are attached to the vibrating table from below. These motors are frequency-controlled and have eccentric disks on the shafts. Due to imbalance, the motors create a vibration that is transmitted to the upper table through the samples of the damping devices being examined. The upper table is equipped with the measuring equipment. Additional sources of vibration are the harmonic components of the voltage generated by power electronic converters at the terminals of the stators of two asynchronous motors. Modeling allows obtaining quantitative characteristics of the studied devices damping in wide ranges of material properties, geometric parameters and control algorithms. The mathematical model of a mechanical system is based on the Lagrange equations and electromechanical energy conversion by electric motors. This model allows for analyzing various options of dampers with various external and control impacts.
