Parametric Evaluation of AC Losses in 500 MVA/1.1 kA High Temperature Superconducting (HTS) Cable for Efficient Power Transmission: Self Field Analysis

High Temperature Superconducting (HTS) cables are used for efficient power transmission. In the present work, AC losses in High Temperature superconducting cable due to self field with various parameters are calculated and validated with the published results. A 500 MVA / 1.1 kArms HTS transmission cable operating at 50 Hz is considered for the AC loss (self field) calculations. The major AC losses arise due to self field in the HTS cable and can be obtained by the approximated Norris equation. Two different superconducting cables, one with BSCCO and the other with YBCO tapes are considered for the present analysis. For a transport current of 1.1 kArms, the analytically calculated self field loss is 0.4 W/m (with BSCCO tape) and 0.5 W/m (with YBCO tape) respectively are comaprable with published experimental results.
