The invention discloses an intelligent substation process layer switch configuration information analysis method, including the following steps that: 1) a background host first parses an SCD file of an intelligent substation, and extracts valid information under an IED node in the SCD file and under a communication node in the SCD file of the intelligent substation, stores the valid information ina database, and distinguishes the information stored in each table by using different table names; 2) the background host executes a pre-designed database script file, and finally generates a GOOSE/SV release control block signal flow table; and 3) the background host extracts and converts the information in the control block signal flow table, and exports a switch VLAN, a multicast forwarding table and port default VLAN information as configuration files. By adopting the scheme of the invention, intelligent substation process layer switch configuration files can be rapidly and accurately generated and delivered to a switch to complete automatic configuration, and thus the efficiency of forwarding table configuration of a switching device at an intelligent substation site can be greatly improved, and an effective means of reducing artificial configuration errors can be achieved.
