The invention discloses an anode grounding reclosing method used for a maglev vehicle power supply system. The anode grounding reclosing method includes the steps that when a short circuit occurs, tripping operation is conducted on an up link and a down link; the up link is switched on; whether a tripping operation signal is given out again or not is judged, if not, it is judged that the anode grounding short circuit point is located in the down link, and exiting is conducted; or else, it is judged that the anode grounding short circuit point exists in the up link, tripping operation is conducted on the up link, and shutting is conducted; switch-on is conducted on the down link; whether the tripping operation signal is given out again or not is judged, if not, it is judged that no anode grounding short circuit point exists in the down link; or else, it is judged that the anode grounding short circuit point exists in the down link , tripping operation is conducted on the down link, and shutting is conducted. By means of the anode grounding reclosing method, a direct-current high-speed circuit-breaker can be effectively protected, and damage of the direct-current high-speed circuit-breaker due to switch-on/switch-off of the direct-current high-speed circuit-breaker within a certain period of time is avoided; meanwhile, the position of the short circuit point is determined through tentative switch on, the short circuit can be cut rapidly, and effective operation of a fault-free circuit is guaranteed.
