Determination of the Parameters of a Compensating Unit in a Traction Power Supply System with a Booster Transformer

Dependence of the concentration of small gas impurities in the air basin of the Southern Baikal region on synoptic and meteorological conditions according to the Listvyanka station

“…However, in almost half of the cases, the peaks were short-term. It is a common fact that atmospheric flows are changeable 18 , and plumes from elevated anthropogenic sources can meander either flowing into the station or passing by. In order to simplify the further analysis, the bursts lasting less than 2 hours were excluded from the research.…”

Simulation modeling balancing current in the traction network of a substation group

“…As can be seen from the bar chart, these differences usually differ by an average of 20-30%, so equalization of the voltage on-load tap-changer will be ineffective [1,6]. An automatic balancing current reduction device is proposed [1], which consists of a block of voltage addition and contains an input transformer, an rectifier [7,8], a voltage inverter, a rectifier filter, an output filter [9] and a voltage-boosting transformer [3]. The additional voltage is formed as follows.…”

“…Thus, the energy indicators of the electrified railway are reduced, and Russian Railways Company incurs economic damage from imperfections in the interfacing of external and traction power supply systems. Some disadvantages in the joint operation of the external power supply system with the traction network are caused by the simultaneous electrification of the railway and settlements, industrial and agricultural loads in the regions [1][2][3].…”
