Abstract

Presented here is the development of a time stepping coupled finite-element state-space (CFE-SS) modeling environment, totally within the natural time domain ABC flux-linkage frame of reference, to predict the steady-state machine parameters and performance characteristics, including laminated iron core losses, of salient-pole synchronous machines. The time stepping CFE-SS model allows one to rigorously account for the full synergistic impact of space harmonics and time harmonics on the machine parameters and performance characteristics.
