“…Note that the components of the vector payoff (2) are nonlinear functions of the vector of spatial arrangement and geometric sizes of SC, as well as the parameters of the regulator X and uncertainty parameters vector d are calculated on the basis of the Maxwell equations solutions in the quasi-stationary approximation [28][29][30][31][32][33][34][35][36].…”

The paper presents results of synthesis, theoretical, and experimental studies of a robust system of active shielding of the magnetic field generated by overhead power lines with triangular conductor arrangements. The synthesis is based on the solution of a multi-criteria stochastic game, in which the vector payoff is calculated on the basis of the Maxwell equations solutions in a quasi-stationary approximation. The solution to the game is based on the algorithms of stochastic multiagent particle multiswarm optimization. The possibility of a significant mitigation of magnetic flux density and a reduction in the sensitivity of the system to the plant parameters uncertainty is shown. Three shielding coils are required to shield a magnetic field in a five-story building, and two shielding coils are sufficient to shield the same magnetic field in a single-story building. Practical recommendations are given on the reasonable choice of the spatial arrangements of the shielding coils of a robust system of active shielding of the magnetic field generated by an overhead power line with a triangular arrangement of conductors. The experimental research into the robust system of active shielding model of the magnetic field generated by overhead power lines with a triangular arrangement of conductors and two shielding coils is carried out. The comparison of experimental and calculated results of the magnetic flux density values in the shielding space shows that their spread does not exceed 30 %.

With the development of information technology, electromagnetic radiation becomes a tangible view of the physical (wave) environmental pollution. Modern scientific research aimed at the components of the electromagnetic environment pollution problems mainly involves the anthropocentric approach. There is no procedure for determining the influence of harmful physical factors on biota, in particular in terms of water (Daphnia magna Straus) and air (Drosophila melanogaster L.) environments. A clear system of rationing of maximum permissible levels of electromagnetic radiation, including volume and ecosystems protected areas has not been developed. The article considers the relevant scientific and practical problem of creating a framework for assessing and predicting the negative impact of electromagnetic radiation on the biota related to ethological changes and teratogenesis. The characteristic of all the constituent elements of the system determines the degree of the negative impact of the induction of the magnetic field on the biota: activity, mortality; reproduction; availability, and frequency of Teratology. A method for determining the activity levels of Daphnia and Drosophila total average activity biota was developed and described. The trajectory patterns of Daphnia motion at low activity in the state of stability, with increased activity in the excited state, were created. The results of the research on the negative impact of electromagnetic radiation of industrial frequency on biota were presented. The critical levels of the magnetic field and noise pollution, which cause the depletion and destruction of the test object, the relationship between ethological changes and the occurrence of mutations depending on radiation levels were determined. The biological test objects were proven to minimize the error of the results of determination of electromagnetic effects on the biota, in comparison with the mathematical methods of research.

“…Motors with a higher load overheat and quickly fail also due to the presence of low-quality electricity in the contact network [8][9][10][11][12][13][14]. Motors are repaired at specialized repair enterprises allowing the following deviation of the output parameters according to the GOST state standard: the armature winding -10% and the excitation winding -2% [11][12][13][14][15][16][17][18]. The irregularity of the parameters results in irregular rigidity of mechanical characteristics and in irregular distribution of the load among the motors.…”

The paper deals with the problem of the assessment of the functionality of the multi-motor direct current traction electric drive of the quarry electric locomotive. The problem of the failure of electric drive motors because of extremely unsatisfactory state of the rail tracks and the wear of wheel pairs is analyzed. Taking into account the number of the existing repaired electric motors the probability of fitting up the traction electric drive with the electric motors with the widest electrical parameters variety is determined.
