Intelligent substation IED (Intelligent Electronic Device) configuration file management and control method based on CRC (Cyclic Redundancy Check) check codes

The invention relates to an intelligent substation IED (Intelligent Electronic Device) configuration file management and control method based on CRC (Cyclic Redundancy Check) check codes. The method comprises the following steps: connecting all-station IED virtual terminators with a system configuration tool to generate an all-station SCD configuration file including a CRC check code, extracting IED configuration information from the all-station SCD file, and downloading the IED configuration information into a device; powering on a process level IED device, putting the CRC check code into a GOOSE message to be sent, and forwarding the CRC check code to a station level network through an MMS (Multimedia Messaging Service) message after an opposite-end bay level IED receives the message; after the bay level IED device is powered on, transmitting a CRC check code of the bay level IED device to the station level network through the MMS message by the bay level IED device; and receiving the CRC check code from the station level network by a configuration file management module installed in a station level of an intelligent substation, resolving the all-station SCD file, extracting a virtual terminator CRC check code of the IED, and judging whether the two CRC check codes are consistent or not by comparison. Through adoption of the method, checking on whether GOOSE virtual terminator configuration information downloaded into the IED is consistent with corresponding GOOSE virtual terminator configuration information in the all-station SCD file or not can be performed effectively.
