PROBLEM TO BE SOLVED: To provide a distributed power supply device capable of detecting failure reliably.SOLUTION: A distributed power supply device 10 includes a power supply section 14, a power lead-out section 11 performing power lead out processing, a power supply control section 12 performing power read processing and a target power lead-out processing for leading out the target supply power value in the power supply section 14 so that reverse flow of power from a power line 2 to a power system 1 does not occur, and target power transmission processing for transmitting the target supply power value to the power supply section 14, a current information changing section 15 provided in the way of a current signal line 6, and capable of changing the actual current value transmitted from a current detector 4 to a predetermined reference current value, and a failure determining section 13 for determining whether or not a failure is occurring at least in any one of the power lead-out section 11 and power supply control section 12 based on a power value read in the power read processing by the power supply control section 12 when the current information changing section 15 is changing the actual current value to the reference current value, or the target supply power value transmitted from the power supply control section 12 to the power supply section 14.SELECTED DRAWING: Figure 1 |
