Abstract
The article discusses the results of statistical and field studies of the energy consumption modes by the traction and non-traction loads in the overhead contact system (OCS) of the on-ground urban electric transport vehicles in the warm and hot seasons and the associated changes in the operation modes of an NKE-3GT stationary buffer energy storage. It is shown that the reduction of non-traction load, which takes place mainly in the warm season, entails a redistribution in the amounts of surplus and useful energy of electric rolling stock regenerative braking toward surplus energy and, hence, a growth in the surplus regeneration energy flows through the buffer energy storage.
