Abstract
The article reflects the results of statistical and field studies of the modes of energy consumption for traction and non-traction load in the CS of ground-based mountain electric transport during the operation of the stationary buffer energy storage NKE-3G. It is shown that the volumes of useful and excessive recovery of braking cars depend on the availability and capacity of the load in the CS. A stationary energy storage device can operate as a controlled load and a peak generator and allows you to increase the useful use of recovery energy by reducing the volume of excess recovery. It has been established that the stationary storage device returns the excess recovery energy for reuse not only when it issues a previously stored part of it, but also during charging by replacing the traction substation as a power source of a useful network non-traction load to the part of excess recovery redirected from the brake resistors of the recuperating car to the contact network. The last effect of saving network energy consumption was discovered for the first time and was called the "KBK effect". The volume of this substitution is comparable to the volume issued by a stationary energy storage device. On-board drives do not allow to implement the "KBK effect".
