The invention discloses an intelligent anticorrosion system and an anticorrosion method for a substation grounding device. The intelligent anticorrosion system comprises a working power supply, an automatic control device, an auxiliary anode, a grounding grid and a reference electrode; the working power supply, the auxiliary anode, the grounding grid and the reference electrode are connected to the automatic control device; and the auxiliary anode, the grounding grid and the reference electrode are buried underground. According to the intelligent anticorrosion system and anticorrosion method for the substation grounding device, the metal material of the grounding grid which is corroded from the outside to the ground provides cathode direct-current current through the design of an additional current cathode protection based on the electrochemistry theory of metal corrosion; and the effect of protecting the grounding grid can be achieved and the purpose of saving money can also be achieved by adopting the groun
