The present invention relates to an uninterruptible power system for electricity facilities of a large building. More particularly, the uninterruptible power system is, under normal circumstances, separately operated for a low-risk (greater than 100V and less than 700V) load facility and a high-risk (greater than 700V and less than 7,000V) load facility. Further, when the facilities are checked or repaired, or when legal inspection is performed, or when an accident occurs, integrated operation is enabled so that the uninterruptible power system supplies power in an uninterruptible power state without stopping the operations of the facilities within the building. Simultaneously, a customer electricity load facility is separately operated as an annual load facility or as a seasonal load facility, as an uninterruptible power load facility or as an interruptible power load facility, and as a low-risk load facility or as a high-risk load facility. Thus, the uninterruptible power system for electricity facilities may be flexibly used according to the power operations of the electricity load facilities and increases in facility capacity. According to the present invention, the customer electricity facility receiving the electricity transmitted or distributed from different substations and different distribution stations may, under normal circumstances, be separately operated as the low-risk load facility or the high-risk load facility. Further, when the facilities are checked or repaired, when legal inspection is performed, or when an accident occurs, integrated operation is enabled so that the uninterruptible power system may supply power in the uninterruptible power state without stopping the operations of the facilities within the building. Thus, economic harm due to a power interruption may be prevented. |
