The need to provide the required electrical capacities of the transport infrastructure facilities of the Baikal-Amur and Trans-Siberian highways

THE PURPOSE. To study the need to provide the required electrical capacities of the transport  infrastructure  facilities  of  the  Baikal-Amur  and  Trans-Siberian  highways.  Today, increasing the transportation capacity of the railway transport system in the Eastern direction is an  important  transport  task..  The  solution  of  problems  related  to  the  creation  of  transport infrastructure  is  inextricably  linked  with  the  creation  of  sources  of  electric  power  in  the presented  scientific  work,  the  authors  analyzed  the  technical  failures  of  the  equipment  of traction substations of the railway line. This analysis revealed that the main cause of equipment failures  of  the  traction  power  supply  system  is  equipment  wear.  It  accounts  for  about  45%  of failures, which is certainly a lot. METHODS. In order to identify technically weak zones on the established  section  of  the  railway  line,  taking  into  account  the  passage  of  heavy  trains  for  the prospective development of the Baikal-Amur and Trans-Siberian highways, traction calculations were  performed  using  the  Kortes  software  package  as  part  of  the  increase  in  freight  traffic  in the eastern direction. RESULTS. The calculated values obtained with the existing dimensions of the organization of train traffic allowed us to conclude that the traction power supply system of the  section  in  question  does  not  allow  to  provide  the  necessary  level  of  traction  network parameters  and  skip  the  planned  train  flow.  The  largest  number  of  failures  falls  on  the equipment of traction substation No. 4, which necessitates the replacement or modernization of this  equipment.  CONCLUSION.  The  expediency  of  reconstruction  of  traction  substations  is determined, taking into account the prospective state of operation of the site.
