Modeling Onboard Energy Storage Systems for Hybrid Traction Drives

Marketing and commercial problems and perspectives for interaction between participants of the transportation process

“…7 [8][9]. The monitoring demonstrated the following issues and bottlenecks [10,11]: such criteria as «meeting delivery dates», «level of transport infrastructure development » and «meeting the demand for transportation» lost 2 points each; -such index as "availability of carriages of the required type in the required quantity" decreased by 11 points at once; -such index as "cost of services of JSC Russian Railways" decreased slightly by only q point; -such criterion as "cost of services of operating companies" dropped by 9 points for the quarter; -such index as "supply of carriages for loading / unloading on schedule" decreased slightly lessby 3 points; -such criteria as "technical condition of carriages" and "cargo safety" left at the level of the first quarter of 2021; particular items were identified that "grew" in the eyes of the participants of the transportation process, e.g. "efficiency of approval of applications" (plus 1 point) и "information technology level and efficiency of transfer of accounting documents" (plus 3 points).…”

Automatic Voltage Stabilization of an Electric Rolling Stock Catenary System

“…As has been noted in [1][2][3][4], the influence on the catenary system can be reduced by equipping ERS with an energy storage device (ESD). This device will allow accumulating braking energy and using it in subsequent accelerations.…”

“…Similarly to the installation of an ESD on the rolling stock [1][2][3][4], the installation of ASCSs in heavytraffic areas will weaken the influence of the ERS on the catenary system, but with a lower number of ESDs and without increasing the ERS weight.…”
