Research conclusions:(1)The energy consumption of medium and low-speed maglev train is more than urban rail transit train.(2)The traction substation and step-down substation set basically the same as urban rail transit，and there is no stray current protection issues.(3)By relying on braking energy absorption devices which set in the substation to brake the train，theoretically it'.s the same as urban rail transit，but the medium and low-speed maglev projects take more 10 kV power supply. In order to avoid the impact to the 10 kV power supply system，resistance energy dissipation type should be adopted. ( 4)Traction power supply network and reflux are advised to adopt contact rail，and due to the presence of the train landing，the contact rail should adopt the side touching style.(5)For safety，the grounding when the train stops，as well as the lightning protection in elevated bridge section，should be well done.(6)The research result can be applied in the research and construction of medium and low-speed maglev project，and it has a significance for the monorail traffic engineering.
