Introduction and Practical Use of Energy Storage System with Lithium-ion Battery for DC Traction Power Supply System

摘要

In this paper, concerned with an energy storage system (ESS) with Li-ion battery for DC traction power system, a study about planning of introducing ESS and the performances of two examples in actual operation are described. Through this study, a suitable condition for introducing ESS with respect to headway of trains was obtained and confirmed by analysis measurements. Further, the effects of adjusting threshold voltages of charge and discharge on the practical use of ESS are also described.
