摘要:
高温超导磁悬浮列车运行过程中, 由于磁体自身存在工作损耗难以实现恒流运行, 寻找适用于高温超导磁体的运行补偿供电方法成为其能否稳定可靠运行于轨道交通环境的关键. 本文基于磁耦合非接触供电技术, 提出一种适用于高温超导磁体的非接触补偿供电方法, 利用电路理论建立电路等效模型, 对电路结构进行了优化设计. 考虑到电路参数对于系统性能的影响, 根据电磁场理论, 对线圈结构进行了设计优化. 通过搭建非接触供电系统实验装置, 对系统特性、不同线圈结构对磁体供电系统的影响进行了研究, 验证了本文所提出的非接触补偿供电方法的可行性.

Abstract:
During the operation of high temperature superconducting maglev train, it is difficult to achieve persistent current operation due to the working loss of the magnet itself. Finding the compensation method suitable for high temperature superconducting magnet becomes the key to its stable and reliable operation in the railtransit environment. Based on magnetic coupling contactless power supply technology, this paper proposed a contactless compensation method suitable for high temperature superconducting magnet. With the utilization of circuit theory, firstly the establishment of circuite quivalent model was finished. Further, optimization of circuit structure was done by utilizing the model. Considering the influence of circuit parameters on system performance, the coil structure was designed and optimized according to the electro magnetic field theory. By constructing the experimental prototype of contactless power supply system, the effects of system characteristics and different coil structures on the contactless power supply system were studied, finally the feasibility of the method proposed in this paper was verified.
Key words:  contactless powersupply, high temperature superconducting material, maglev train
