Abstract
A power distribution system that can be used in naval ships and submarines includes a first propulsion drive system including a propulsion motor having superconducting (preferably high temperature superconducting (HTS)) rotor windings and a power converter. A first propulsion power generation system supplies power to the first propulsion drive system and includes a generator having superconducting (preferably HTS) rotor windings and a power converter. A first power generation system includes a power source for supplying power to a first service distribution system that includes a dc distribution busbar (optionally implemented using HTS cabling or busbar) for carrying a distribution voltage and a distribution current, and a switchboard that includes protective switchgear with contacts. A power converter is used to connect the power source to the switchboard. The power converters are regulated according to a power source foldback and stabilizing characteristic. An electric load is supplied with power from a zonal power supply unit that forms part of a zonal power distribution sub-system. The electric load and the propulsion motor are regulated according to a load shedding and stabili…
