Abstract
A system includes four high voltage direct current (HVDC) feeders, each having a first contactor configured for selectively connecting a positive terminal of an HVDC source to the respective HVDC feeder, and having a second contactor configured for selectively connecting the respective HVDC feeder to an HVDC bus. A power converter can be configured to use feedback to locate a fault when a fault arises, and to isolate the fault by opening of the contactors as needed for continued operation of as many of the HVDC feeders as possible after clearing the fault.
