Development of Energy Storage System for Urban Transit System
도시철도용 에너지저장시스템 개발에 관한 연구
The energy storage system is considered to be one of the useful devices for energy storing and recycling. the energy storage system can save energy cost and stabilize the system voltage. This paper presents the development of two energy storage systems. One is 750V system for light rail system. the other is 1500V system for heavy rail system.
