Finite Element Assisted Method of Estimating Equivalent Circuit Parameters for a Superconducting Synchronous Generator With a Coreless Rotor

The paper outlines methods developed to obtain circuit parameters of a superconducting synchronous generator with a coreless rotor. The need for full three-dimensional (3D) finite element modeling is emphasized and appropriate techniques devised to estimate relevant equivalent characteristics. The m...

Description
Summary:The paper outlines methods developed to obtain circuit parameters of a superconducting synchronous generator with a coreless rotor. The need for full three-dimensional (3D) finite element modeling is emphasized and appropriate techniques devised to estimate relevant equivalent characteristics. The methods described use steady-state ac models, predominantly in the rotor frame of reference; the use of transient or full rotating machine models is avoided.
