Abstract :
A distributed power supply system with highly efficient characteristics is being developed to replace conventional centralized power systems. In this system, as in conventional power systems, a standby energy system composed of batteries and engine-generator sets is used as a back-up system for the commercial power lines. However, the distributed power system, except for the engine-generator set, is installed in the telecommunications room. Thus, the floor load limitation is an important design factor. Reliability analyses show that the distributed power system should be designed using a fully duplicated engine-generator set; with battery reserve time reduced to one-sixth that of conventional centralized power systems; and with transfer switch unavailability designed to be less than 5×10-7
