- Abstract
- Superconducting field coils consist of race-track-type double pancake (DP) coil modules fabricated using high-temperature superconducting (HTS) wire with high current density and zero resistance. The structural shape of race-track-type DP coils strongly influences the intensity and the shape of the magnetic flux density in the air-gap, which determines the generator electrical output and the superconducting field coil performance. Hence, the structural shape of a superconducting field coil is very important in designing a large-scale superconducting generator. We analyze the characteristics of a 10-MW-class HTS generator using 3-D finite-element analysis software to investigate the electromagnetic effects due to the structural-shape changes in the superconducting field coil.
