Electric energy storage in DC traction power supply systems

Abstract

Electric energy storage systems have been known for a long time. In order to store energy the following
solutions may be used: mechanical (rotating wheels, compressed air), chemical (hydrogen), electrical (batteries
and supercapacitors), and others. Supercapacitors and batteries are most common in electric traction systems.
They are installed in vehicles and substations. They are most widely used in traction power supply systems of
600 V DC and are mainly intended for storage of braking energy, which allows saving energy. Work has begun
on the storage of braking energy in the 3 kV DC system and research and measurements are carried out. In the
paper, the concept of an energy storage system designed to be used on 3 kV DC power supply system is
presented, where batteries are used as the energy storage systems. It is designed to work in traction substations
and sectioning cabins. It can be used on all DC traction power supply systems.
