The invention discloses a method for automatically obtaining zero order parameters of power grid elements. The method comprises the following steps of (1) timely and automatically obtaining zero order parameters from a relay protection setting value off-line setting database, specifically, configuring an output program on the relay protection setting value off-line setting database, periodically outputting zero order parameter data files from the database, and storing the zero order parameter data files locally; (2) invoking an FTP command to update the zero order parameter data files to a server appointed by a safe III area; (3) after a reverse isolation device detects the update of the files, automatically triggering to transmit the files to a relay protection setting value online verification system data server arranged in a safe II area; (4) inputting the zero order parameter data into the database by the relay protection setting value online verification system. According to the method for automatically obtaining the zero order parameters of the power grid elements, which is disclosed by the invention, the obtaining of the zero order parameters of the power grid elements from the relay protection setting value off-line setting database and the execution of a verification computation operation are capable of being fully automatically realized, so that the maintenance workload is reduced; the zero order parameter data files of the power grid elements is capable of being obtained over the safe areas.
