Abstract: Methods and apparatus for protecting a direct-current (DC) electric power distribution system that includes one or more AC/DC converters and/or one more DC/DC converters, and one or more loads, connected by DC buses. An example method, which is carried out in response to the detection of a fault somewhere in the system, begins with limiting an output current of each of one or more of the converters so that each of the limited converters outputs a limited DC current at or about a corresponding predetermined current level. After the current limiting of the one or more converters has taken place, one or more protection devices in the system are activated, where the activating at least partly depends on the limited DC currents being at or about the predetermined fault current levels.
