The invention discloses a storage and quick indexing method for mass data of an intelligent substation. By the combination of the characteristics of the mass data of the intelligent substation and an I/O storage mechanism of LINUX, indexes are created for stored data of the substation, the mass data can be quickly stored on the premise that an existing storage principle of an operating system is not changed, disk fragments are reduced, and a google engine indexing technique LevelDB is packaged and introduced in storage of the mass data of the intelligent substation. The storage and quick indexing method has the advantages that the speed is high, deployment is simple, and generated disk fragments are fewer, and by the introduction of the storage and quick indexing method for the mass data, an effective means is provided for conducting quick search and quick problem positioning on events through a message record and analysis system when accidents happen in the running process of the substation, so that the period for analysis and positioning of faults and events of the substation is shortened, and reliability of running maintenance on the substation is improved.
