Intelligent substation SCD configuration file homology detection method

Abstract

The invention discloses an intelligent substation SCD (Substation Configuration Description) configuration file homology detection method which comprises the following steps: step 1, when an SCD fileis signed in for the first time, 32-bit check code calculation is carried out on SCD full text information by utilizing a cyclic redundancy check code CRC to generate a unique code; 2, when the SCD issigned out, the unique code is signed out along with the SCD file; the upgraded version is modified on the basis; 3, when the SCD is signed in, unique code comparison is carried out firstly, if the unique codes are inconsistent, it is indicated that the signed-in version is not upgrading and refusing to sign in on the signed-out version, and if the unique codes are consistent, signing-in, versionreplacement and unique code updating are allowed; the homology problem of signing out and signing in the SCD file in the SCD management and control system of the intelligent substation is solved.

Description

technical field [0001] The invention belongs to the technical field of configuration information of smart substations, and in particular relates to a homology detection method for SCD configuration files of smart substations. Background technique [0002] With the advancement of my country's new energy strategy and the deepening of smart grid construction, smart substation technology based on the IEC61850 standard (the only global standard in the field of power system automation) has also achieved unprecedented development in my country, and the smart grid has entered a comprehensive construction stage. Substations are constructed according to the standards of smart substations, and some traditional substations need to be upgraded according to the standards of smart substations. The technical development characteristics of smart substations determine that the operation and maintenance process of smart substations is very dependent on SCD (substation configuration information)...

AI Technical Summary

Problems solved by technology

[0003] (1) After a large number of smart substations are put into operation, the configuration files are stored by individuals and managed by integrators, which cannot guarantee the standardization, correctness and uniqueness of the configuration files of smart substations;

[0004] (2) After the smart substation is put into operation, there are a large number of engineering projects such as technical transformation, overhaul, and overhaul. These engineering projects will rely on and may modify the configuration files of the smart substation. Process management and control of configuration file transfer, defect handling, and defect evaluation among maintenance units, regulatory departments, and other departments;

[0005] (3) After the smart substation is put into operation, because the operation and maintenance work must rely on the configuration file, there is a lack of means of management and control of the configuration file based on the operation and maintenance process, so as to ensure that the version of the configuration file after the operation is consistent, unified and standardized
