“…There are several published articles in literature, reporting the effect of harmonic components on AC loss in superconducting tape or coils, analytically or experimentally [6][7][8][9][10][11][12][13][14][15][16][17][18][19]. In [9], an analytical method based on Bean's model is presented in order to calculate the AC loss of superconducting strips carrying higher order harmonic currents.…”

Application of high temperature superconducting devices become promising in power networks, and transportation, including ship, train and electric aircraft propulsion systems, with the advantages of light weight, compact size, and high efficiency, compared to conventional devices. In reality, electric networkseither in grid or transportation propulsion system -are polluted with harmonics due to the widespread use of power electronic devices and nonlinear loads. It is essential to explore the dependency of harmonic AC losses of different coil configurations carrying non-sinusoidal current. We modelled and compared harmonic AC loss behaviors in three coil configurations, single pancake coil (SPC), double pancake coil (DPC) and solenoid coil (SNC), where SPC and SNC are wound by identical wire length and DPC has twice conductor number compared to SPC. The research work has been carried out by means of H-formulation finite element method in a 2D axisymmetric modelling environment of COMSOL Multiphysics. We explored and reported AC losses in these three coil structures carrying nonsinusoidal current with the 3 rd and the 5 th harmonic orders, respectively, under different total harmonic distortion (THD) and fundamental current levels. It has been concluded that AC loss in these coils firstly decreases with the increase of the 3 rd harmonic content, when THD of the 3 rd harmonic < 0.2; and increase with the increase of the 3 rd harmonic when THD >0.2. AC loss in coils monotonically increases with the increase of the 5 th harmonic, drastically. We found that AC loss in SPC carrying the 3 rd harmonic and the 5 th harmonic at different THD are more than 3.8 times of that in DPC; AC loss in SPC carrying either 3 rd or 5 th harmonics at different THD are around 4.5 times of that in SNC.

Previous studies on magnetization AC loss of high temperature superconducting (HTS) coated conductors (CCs) taken into account the ideally sinusoidal external magnetic field, or non-sinusoidal by considering only the harmonics in phase with the fundamental component. However, realistically magnetic field often contains harmonics with different phase angles and amplitudes. In this work, magnetization AC loss in HTS CC was studied, considering the phase angle φ of each harmonic; assuming superconductor is subjected to external magnetic field which is distorted by the 3 rd and the 5 th harmonics. Phase angle of each harmonic was considered in the range of 0 to 2π and amplitude of fundamental magnetic field, was assumed as 10, 20, 50, and 100 mT. Different distortion level of magnetic field was considered too. It is concluded that phase angle of field harmonic has a significant effect on magnetization loss of HTS CCs.

“…The magneto-optical imaging (MOI) technique was used to visualize the magnetic flux density to obtain the real magnetic field distribution in HTS tapes, and the horizontal arrangement of HTS tapes has been studied [9,10], but the magnetic field distribution of the vertical arrangement could not be completely observed due to the limitations of MOI technique [11]. Alternatively, simulations based on the finite element method (FEM) are applied widely in superconductivity research [12][13][14][15], FEM analyses have been carried out on the current density of a single tape and the AC losses in the horizontal and vertical arrangements [16][17][18][19][20]. With only two or three tapes, these basic FEM models cannot simulate the real magnetic field and current distribution of periodically arranged HTS tapes in practice, and they also can not verify or modify the analytical models, which are often used for loss estimation.…”

The operation of a high-temperature superconducting (HTS) device is strongly related to its electromagnetic fields and conditions. It is necessary to study the electromagnetic interaction of proximity HTS tapes integrated such as placed in the horizontal or vertical direction, which is important for the design and optimization of HTS devices. This paper presents a numerical model of periodically arranged HTS tapes using the finite element method (FEM). The numerical method has been developed to build the equivalent periodical arrangement of infinite HTS tapes and applied to simulate two basic arrangements, horizontal and vertical periodical arrangements. The magnetic field and current distributions of HTS tapes by periodical arrangements have been investigated. The effects on critical current with different arrangements have been illustrated. It is found that the Y-stack can reduce the current carrying capacity while the X-array can increase that in comparison to a single tape. The differences between the FEM results and analytical models have been analysed and also compared with the Norris model. The two mathematical models derived for AC loss prediction have shown higher accuracy than the existing analytical models. This study presents an effective method to optimize the electromagnetic fields, estimate the AC loss, and shows the phenomenon of central tapes in an HTS array, which could be potentially used in performance analysis of superconducting devices, e.g. HTS transformers.
