Abstract

The optimal design of a 2.4 MVA high temperature superconducting (HTS) generator is presented. The main features of its configuration are the adoption of the evaporative cooling stator and the magnetic flux oriented rotor. The cross section of the field winding in rotor is in circular arch shape, and the magnetic diverter shims are embedded between HTS coils. The technical and economical parameters of the innovated HTS generator are improved effectively. With the help of the commercial software ANSOFT RMxprt and EMpulse modules, the optimal design and detailed calculation of electromagnetic and thermal fields are implemented.
