METHOD OF SELECTION OF PARAMETERS REACTIVE POWER COMPENSATION
IN TRACTION AC NETWORKS
A. . Minina1, V. I. Panteleev1, E. V. Platonova2
Siberian Federal University 26 Kirenskiy street, Krasnoyarsk, 660074, Russia. -mail: pvi0808@rambler.ru 2Khakas Technical Institute - branch of the Siberian Federal University 27 Shcetinkin street, Abakan, 655017, Russia. E-mail: eplatonova@yandex.ru
The authors show a program for calculation of normal and resonant modes with a procedure of calculation of a network with nonlinear load on the example of traction substation, which allows, on the basis of the analysis
of frequency characteristics of the input resistance = f (v), to appreciate the range of currents and voltages in the
network elements, and to assess the levels of active losses and overloads of compensating devices with currents of higher harmonics.
Keywords: reactive power compensation, resonance, input impedance network, compensating device, harmonics.

GROUP-THEORETICAL ANALYSIS OF Ni5GeO4(BO3)2 POTENTIAL MAGNETIC STRUCTURES
I. I. Nazarenko, S. N. Sofronova
Siberian State Aerospace University named after cademician M. F. Reshetnev 31 Krasnoyarskiy rabochiy prospect, Krasnoyarsk, Russia. E-mail: ilnz007@live.ru
The work presents a group-theoretical analysis which makes possible to determine Ni5GeO4(BO3)2 crystal potential magnetic structures. The obtained information will help to analyze and interpret experimental data, while determining the true magnetic structure and the mechanisms of magnetic transitions in the compound being tested.
Keywords: magnetism, group-theoretical, ludwigites.
