Abstract :
[en] We present the comparative design results of a 1.5-MW-class higherature superconducting synchronous machine (HTSSM) by considering various commercial 2G coated conductors (CCs). We focus on the estimation of economic factors to manufacture a more cost-effective HTSSM. A key design issue in HTSSM development is the adoption of superconducting wire among various types of recent commercial 2G CC tapes with different dimensions, critical current performance, and cost-performance ratio that affect the HTSSM performance, thermal losses, and CC tape-length usage. Therefore, we first perform the electromagnetic and thermal design of a 1.5-MW-class HTSSM considering three types of 2G CC tapes. Then, we present the comparative analysis results related to economic factors.
