Abstract

The present disclosure suppresses increase in device cost in a DC power distribution system that can disconnect a distribution line on which a short-circuit failure has occurred, from an output path. This DC power distribution system includes: a plurality of power conversion devices; one DC busbar; a plurality of distribution lines; a plurality of first current interruption portions respectively connected to input sides of the power conversion devices; a plurality of second current interruption portions connected between the power conversion devices and the DC busbar; and a plurality of third current interruption portions respectively provided on the distribution lines. Interruption current values of the third current interruption portions are set to smaller values than a maximum allowable current value of the power conversion device in which short-circuit current will reach the maximum allowable current value in a shortest time.
