要約(英語): When a magnetic levitation rail carrying a superconducting coil moves at high speed, an electromagnetic induction voltage is generated in the surrounding telecommunication line due to Faraday’s electromagnetic induction. This phenomenon is analyzed by AC/DC module of COMSOL Multiphysics. The telecommunication line is modeled for a common mode flowing in a loop between the telecommunication line and the ground. As a result, we devise a method to calculate the induced voltage to the telecommunication line loop by differentiating in position the position dependency of the superconducting coil with respect to the magnetic flux linking the telecommunication line loop. In addition, to confirm the validity of the calculation method in COMSOL, we compare flux linkages for a model on the ground surface and a model in the complete free space, and also compare the results calculated with MATLAB by modeling with a lumped constant circuit and the results calculated with COMSOL.
