<p><P>PROBLEM TO BE SOLVED: To provide a power supply cooperation system and an uninterruptible power supply device, for mutually using electric power among a plurality of uninterruptible power supplies and preventing electric leakage. <P>SOLUTION: A power cooperation system 100 is so configured that, upon occurrence of power failure, a communication part 116 of uninterruptible power supplies 11, 21, and 31 communicates with a communication part 52 of a power distribution control part 5 through electric lines 6 and 7, and an MCU117 of the uninterruptible power supply 11 determines whether the power lines 6 and 7 are normal or not based on whether communication is enabled or not. The power distribution control part 5 cuts off the power lines 6 and 7 if determined to be not normal. The uninterruptible power supplies 11, 21, and 31 supply the electric power accumulated in an accumulation part 112 to the power lines 6 and 7 which supply the electric power to the uninterruptible power supplies 11, 21, and 31 from an outdoor power system. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
