<P>PROBLEM TO BE SOLVED: To provide a DC power distribution system for protecting the system against overload by controlling so that the power supply from a DC power supply required from power supply lines can come within a limited range. <P>SOLUTION: The DC power supply 1 supplies DC power to a DC apparatus 2 via power supply lines Lpa, Lpb, Lpc. Limiting means 4 for limiting at least current or voltage are each inserted into the power supply lines Lpa, Lpb, Lpc for each system. A current sensor CT as a line information detecting means is provided for each system of the power supply lines Lpa, Lpb, Lpc, and a control means 5 controls the limiting means 4 for each system on the basis of load information for each system obtained using the current sensor CT to limit the DC power to be supplied for each system. <P>COPYRIGHT: (C)2009,JPO&INPIT |
