Abstract
The energy recovery flows in the rolling stock of mountain electric transport during braking are considered. The influence of the network load power on the useful recovered energy flow directions during rolling stock braking is determined. The energy consumption coefficient for traction and non-traction needs is derived as an intrinsic characteristic of the system for performing transport work in the GET. The change in the energy recuperation flow patterns during charging of a stationary energy storage device in the contact network is analyzed. The effect of additional energy saving by a stationary storage device, not previously described in the literature, has been revealed in addition to the fact that it supplies previously stored energy of excessive recovery to the load in the contact network. Additional useful utilization of the mobilized excess energy recovery occurs during the drive charging, when part of it is consumed directly, i.e. without staying in the drive, by the network load, which does not occur without the stationary drive presence. This phenomenon has been given the name "BCF effect". The basis is laid for the method for calculating the direct consumption amount by the network load of the mobilized excess recovery during the drive charging at the current level of accounting tools development and application.
