Abstract
High-temperature superconducting (HTS) magnets have been developed and studied for various high-field applications worldwide. Rare-earth barium copper oxide (REBCO), known as a second-generation HTS, shows the high performances even in a high field. To investigate the REBCO magnet behaviors, the partial element equivalent circuit (PEEC) model is widely used as an electromagnetic simulation method. A great number of partial elements are required to simulate local phenomena in detail. It takes a long time to compute the local mutual inductances in advance. In this paper, the multipole expansion (ME) is introduced as a first step toward a fast computation of PEEC model simulation. 44.4%–50.7% reductions in inductance computation were achieved applying the ME.
