This paper compares the short‐circuit performance of superconducting (SC) generators with three different topologies, i.e. iron‐cored stator and rotor, iron‐cored stator and air‐cored rotor, and air‐cored stator and rotor. The analysis is based on three‐phase short‐circuit fault, and finite element analysis is used for simulation. Following the introduction of specifications of generators, the short‐circuit performances of different topologies are analysed and compared, with the field winding excited by voltage and current excitation sources, respectively. It shows that the short‐circuit performance can be improved by limiting the field current.
