Abstract
An HTS DC power cable is expected to perfectly eliminate transmission loss caused by resistance. However, when the HTS DC power cable is applied to the power system, loss of the HTS DC power cable is generated due to harmonics caused by HVDC converter. We designed and analyzed the HTS DC power cable with a critical current of 1 kA to investigate the loss characteristics using a finite element method package. In this paper, the loss characteristics caused by harmonics in the HTS DC power cable were analyzed according to order and magnitude of harmonics. Based on the analysis results, the critical current of HTS DC power cable considered with the rated current could be determined to minimize the capacity of cooling system for the design the HTS DC power cable.
