Abstract:
To provide a power distribution system which can appropriately eliminate an accident in a distribution line, even if an abnormality occurs in one switch which is provided on a long distribution line.SOLUTION: The power distribution system includes: a plurality of slave stations provided corresponding to a plurality of switches for dividing a long distribution line connected to the bus of a distribution substation into a plurality of sections; and a master station configured to be communicable with the plurality of slave stations. A first slave station among the plurality of slave stations accepts a current input detected at the distribution line, and outputs an open command to a first switch corresponding to the first slave station if the detected current is included within a reference range. When the first switch is not opened by the lapse of a first period after the open command is output, the first slave station requests a second slave station, which is adjacent to the first slave station on the bus side, to output an open command to a second switch corresponding to the second slave station.SELECTED DRAWING: Figure 6
