Power supply system in information communication machine room and power supply control method thereof

摘要

PPROBLEM TO BE SOLVED: To provide a power feed system for an information communication machine room which is suitable as a power feed system of a data center for accommodating a high heat-generating ICT device. PSOLUTION: In emergency such as a power failure, the power feed system is switched to battery power feed without instantaneous interruption. After that, when an engine generator 2b is activated, the power feed is switched to power feed from the engine generator 2b. If the generator 2b is not activated normally, the battery power feed continues. When a battery 5b of an ICT device system 8 is completely discharged in this state, for example, the power feed is switched to a state that SW6b is opened and SW6a, 6c are closed (Fig.4). In this way, both the systems are fed with power from the battery 5a. By such the power feed system, the power feed quality of both the systems can be matched with the same level.
