Abstract
Aim. Comparison of magnetic and transport characteristics of racetrack model coils and open-loop HTS coils.
Methods. Numerical analysis was performed using the finite element method in the Comsol Multiphysics simulation environment.
Results. For these configurations, typical in electromagnetic systems of a HTS generator, the distribution of currents, magnetic fields, and temperatures under the influence of direct transport current were calculated, and losses in alternating current at different amplitudes and frequencies of the current load under liquid nitrogen cooling were calculated.
Conclusion. Under liquid nitrogen cooling, racetrack model coils have better magnetic and transport characteristics compared to open-loop HTS coils, due to their configuration which has a dominant impact. The most advantageous configuration of the coil of the elements of the HTS generator with nitrogen cooling is a racetrack model coil.
