Research on automatic checking technology of intelligent substation configuration data based on feature information of encryption equipment

Abstract

Aiming at the problem of low confidence that the configuration data of communication equipment in smart substation is easy to be interfered by unpredictable factors, the automatic checking technology of configuration data in smart substation based on the characteristic information of encryption equipment is proposed. The verification code generation algorithm based on the device encryption feature information is designed to set an encrypted unique identifier for the device. The work flow of automatic configuration data checking is composed of four steps: reading the data of maintenance terminal, reading the data of drive and acquisition distribution table, automatic checking of intelligent substation configuration data and output record. Through the example analysis of the setting experiment, the automatic checking technology of configuration data based on the characteristic information of encryption equipment can find errors and display correction information in the case of missing data set manually, which improves the accuracy of configuration data information of communication equipment in smart substation and is conducive to the stable operation of smart substation.
