Еxtending the life of power transformers in the reconstruction of traction substations ac railways
The paper presents a mathematical model of the wear of winding insulation of power transformers traction substations AC railways, which takes into account the uneven wear of winding insulation for transformer phases. Extending the life of transformers is made decrease the intensity of wear of winding insulation with the most wear and tear. The corresponding winding connected to the switchgear under the new circuit with the minimum of wear intensity. Connecting transformers in the new circuit on the basis of the algorithm inputs connecting it to the switchgear of the higher, the traction and district voltage substation.
Keywords: traction power supply system of railways AC 25 kV, power transformers, service life, deterioration of winding insulation, substation reconstruction.

Simulation of the mechatronic system based on laser tracking system intended for navigational transit purposes
Deeva V., Ivoylov E., Slobodyan S., Cupin A.
High interference immunity due to precise directionality and monochromatic radiation is the important benefit of the optical, laser and LED systems. However, the predominant features of the optical and laser amplifiers, and today's optical emission source, lead to some trouble. For example, high intensity precise directional electromagnetic radiation is factored into the test program with the use of a portable high-precision system. The most significantly factor is that laser targeting is used for the detection and tracking of dynamic objects of any shapes. However, the moving objects are the short-term objectives or are positioned in the field of vision wider than the laser beam size. Also we investigate, using computational modeling and simulation, the potential of the kD-motion platform to expand the field of vision of the laser systems and we receive influence from other variables.
Keywords: simulation, efficiency, dynamic platform, model, estimation, rough guidance, laser, control, space, guidance system, tracking.
