Abstract
To provide a DC power distribution system that distributes power from a power supply device to a load device via a distribution network, the DC power distribution system including: a measuring instrument that is provided in the distribution network; and a control device that includes a determination unit that acquires, through optical fiber, a voltage value and a current value measured by the measuring instrument, and determines an operation state in the DC power distribution system on the basis of a waveform indicating a change in the voltage value and a waveform indicating a change in the current value.
