Abstract

High capacity UPS and emergency generators are commonly employed at facilities where power interruption is not allowed. Nowadays, combinations of existing commercial incoming power and an emergency generator or combination of multiple generators and CTTS(Closed Transition Transfer Switch) is adopted sometimes for more reliable power supply. In this paper, application of CTTS and STS(Static Transfer Switch) to dual-power line is suggested for highly reliable uninterruptible power. By realizing such a system, construction of incoming power facilities, installation of emergency generator and large capacity UPS can be omitted, through which saving of the installation space and corresponding capital investment can be expected.
