Prefabricated Compact Substation

Communication base station box-type substation power

Designed for 11kV to 33kV networks, these substations support both oil-immersed and dry-type transformers, and are compatible with SF6 or vacuum switchgear. Their compact size reduces land use and shortens commissioning time.

Structure of the energy storage system in the substation

Therefore, this article proposes an energy storage system (ESS) based on Li-ion batteries for regulating the maximum demand of traction substations. An ESS is connected to the DC bus of a railway power conditioner (RPC), which is connected to the two power supply arms of the.
