This paper aims to evaluate the AC loss of a High Temperature Superconducting (HTS) cable with respect to the twisting angle while considering mechanical constraints in an iterative approach. A 1km 22.9kV AC HTS cable was selected in this study to assess the impact of the twisting angle alterations. The electromagnetic behavior of the selected HTS cable was modeled using an Equivalent Circuit Model (ECM). After the implementation of this model in MATLAB/SIMULINK, a series of simulations were performed without the consideration of mechanical limits. They showed that the increase in the twisting angle leads to the decrease of the AC loss. Afterwards, simulations were conducted to reduce the AC loss, while mechanical limits were taken into account. This improvement could reduce the AC loss by 27.41% with a much lower computation time than Finite Element Methods (FEMs).

A type of co-axial DC (Direct current) HTS (high temperature superconducting) cable with self-shielding characteristics large current capacity was proposed. Based on its configuration, the critical current distribution is thus obtained by detailed analysis on magnetic field distribution with different transport current. The analysis shows that this interleaved kind of cable has higher critical current and more compact structure than the existing cable when transmitting large amount of DC current, since there is little magnetic field in the outer space. Additionally this type of cable has functions of two existing structure cables so that it saves more superconducting tapes than the two conventional ones.

Abs t rac t --With the increasing demand of the electric power capacity, the existing power transmission lines cannot satisfy with the growing demand, especially in city of crowded population. As the development of high temperature superconducting ( HTS) power technology, HTS power cable provides a new solution for increasing the capacity of power transmission. However, the quench of the HTS power cable will seriously affect its safety operation. If there are no measures which detect and protect the HTS cable, the cable will be destroyed. Thus, it is significant for the detection of the HTS power cable quench. Presently, detecting the temperature, pressure and flux of HTS cable system are the main methods for quench detection. These parameters respond slowly and can not offer sufficient safety. A quench detection method based onwavelet analysis is proposed for HTS power cable in this paper.Once the voltages and currents of the HTS power cable are extracted by the oscilloscope, the signal and noise can be separated by the wavelet analysis. In this method, the harmonic interference is eliminated, which leads to the precise calculation of the phase difference. In addition, the detecting method can also improve the quench sensitivity ofHTS power cable.Index Terms--HTS (h igh temperature superconducting) power cable, quench detection, simulation, wavelet analysis.
