Dynamic checking method of intelligent substation IED (intelligent electronic device) model configuration correctness based on SCD (security coding device) files

Abstract

The invention discloses a dynamic checking method of intelligent substation IED (intelligent electronic device) model configuration correctness based on SCD (security coding device) files. The dynamic checking method is adaptable to a digital substation or an intelligent substation communicated under IEC61850. The dynamic checking method includes firstly extracting relative IED model information to be detected from the SCD files, then mapping the relative IED model information to be detected into MMS (multimedia messaging service) named variables, and storing the MMS named variables as a data file 1; then communicating with the IED to be detected in a client terminal mode, reading information of each layer of the IED to be detected online through ACSI (abstract communication service interface) model reading service, and storing the information as a data file 2; and finally comparing the model information of the data file 1 to that of the data file 2 to determine whether the model information is identical or not. The dynamic checking method has the advantages that downloaded CID (character identifier) files in the intelligent substation IED and the SCD file information are checked automatically to determine whether the information is identical or not.

Description

technical field [0001] The invention relates to a method for dynamically checking the configuration correctness of an intelligent substation IED (Intelligent Electronic Device) model based on an SCD file, which is used to test whether the CID configuration file downloaded to the IED is consistent with the relevant information of the SCD file imported into the monitoring background , suitable for digital substations and smart substations that adopt the IEC 61850 standard. Background technique [0002] The implementation process of the digital substation project that adopts the IEC 61850 standard is as follows: first, each device manufacturer generates the ICD file of the device through its own device configuration tool, and then provides it to the system integrator; the system integrator is responsible for the overall system configuration according to the design drawings and user requirements. To configure, generate an SCD file on the basis of each ICD file; then, each device...

AI Technical Summary

Problems solved by technology

However, due to design changes, user needs, etc., ICD and SCD files often need to be modified, so there are a large number of versions, and a slight error in cooperation between device manufacturers and system integrators will lead to inconsistent information in ICD files and SCD files; Some device manufacturers directly modify the CID configuration file without going through the system integrator

These problems will cause the version of the CID file actually downloaded to the device to be inconsistent with the version of the SCD file, which may eventually lead to problems such as signal misalignment and communication service access errors.

Signal verification can only be carried out by repeating various relay protection tests (or through the simulated transmission function of the protection device), and the workload is very heavy, resulting in low efficiency and easy omissions and errors
