相互結合を考慮した磁気浮上式鉄道用二相推進コイルのサージ特性 Surge Characteristics of Propulsion Coils Including Mutual Coupling for Maglev
A superconducting magnetic levitation system (Maglev) employs a linear synchronous motor (LSM) with primary side on ground. In the system, a combined levitation and guidance system arranging propulsion coils on the surface of the sidewall is used. Also, propulsion coils are electro-magnetically coupled to each other because they are attached in double layers. Therefore, propulsion coils on the both sidewalls are electro-magnetically coupled with the combined levitation and guidance system. This means that the surge characteristics of the system will be very complicated.<br>As one of the analysis of the electric surge of such an electro-magnetically complicated system of Maglev, we measured the surge between propulsion coils and simulated it using EMTP (Electro-Magnetic Transients Program) in consideration of mutual coupling between coils. After confirming the agreement of the simulated results and the experimental results, characteristics for the practical large system such as Yamanashi Test Line are discussed.
