Abstract

Cost reduction study of 100 MW/500 kWh SMES for load compensation and frequency regulation is performed under Japanese national project. A newly designed CIC (Cable In Conduit) Conductor is developed for the SMES (Superconducting Magnetic Energy Storage). The number of superconducting strand in the cable is reduced with segregated Cu strands. The cross-sectional structure of a strand with CuNi sheath is simplified from the previous design. To reduce AC loss time constant, strands are twisted up to second degree, which is much lower than that of the previous cable design. A short sample of the conductor is manufactured and tested. The test results show that the conductor has good performance for the SMES.
