Evaluation of energy recuperation efficiency for operating conditions of city electric transport

The method of evaluation of energy recuperation efficiency is proposed. This method based on the research of trolleybus power consumption in real operating conditions. It was determined that the part of recuperation energy is about 18% from the energy utilized in traction mode. Also it was estimated that the probability of energy recuperation is about 90% in case of fully paralleled bilateral feeding of traction network and the presence of 14 trolleybuses at the feeding area.
