The simulation and analysis for a new concept of the stator power supply mode of a medium speed maglev system

Aim: The Aim of this paper is to demonstrate the structure of the proposed new stator power supply mode. Methods: analyze the results of some simulation work to see whether the new concept could meet the requirements of the medium speed maglev transportation system or not. The study is based on some simulation work which is done by the software tool developed in the research work in “The 11th Five-year plan” of China. Results: The calculation results indicate that, from the point of view of top speed, that say 200 km/h, the structure of the new concept could meet the requirement of the medium speed system, but further studies are demanded for the engineering application. Conclusion: The advantage of this structure is to reduce the demand for the capacity of the inverters and eliminate the requirements for the cable lines and the stator switches. However, the disadvantage is also explicit. The structure is more complex than its high speed peer, and thus need more complex control strategies. And the structure is more fixed and thus maybe need more invest at the beginning of an engineering project.
