High temperature superconducting (HTS) dc power cables need to be designed to tolerate all potential operating conditions expected on US Naval ships with medium voltage direct current (MVDC) integrated power and energy systems. These operating conditions include normal conditions and all possible fault conditions. Effects from electrical faults in MVDC power systems depend on the type of fault, the architecture of the power generation modules, and the implemented protection and fault management scheme. Various fault scenarios were modeled on a representative MVDC subsystem to estimate the current and voltage levels encountered by HTS dc cables, specifically the energy released into the cable system during faults. This paper identifies the local temperature increase within cryogenically cooled HTS dc cables, and the associated challenges that this potential rise in temperature presents once an electrical fault occurs.
