Smart substation IED configuration information and SCD file consistency detection system and method

Abstract

The invention discloses a smart substation IED configuration information and SCD file consistency detection system and method. The smart substation IED configuration information and SCD file consistency detection system comprises a handheld portable device. On the one hand, the handheld portable device is used for extracting an IED name an SCD file and CRC codes of the SCD file; and on the other hand, the handheld portable device is used for scanning two-dimension codes on an IED display screen to obtain CRC codes of IED configuration information and an IED name of the IED configuration information, and then, completing consistency detection on the CRC codes of the IED configuration information and the CRC codes of the SCD file when the IED name of the IED configuration information is identical with the IED name of the SCD file, and outputting a consistency detection list after all the IED configuration information is detected. Based on an existing detection method, the IED configuration information and SCD file consistency detection system and method have the advantages of more convenient operation and high automation degree. With the system and method adopted, man-made errors can be decreased, and the reliability and efficiency of detection can improved.

Description

technical field [0001] The invention relates to the field of operation and maintenance of intelligent substations, in particular to a system and method for detecting the consistency between IED configuration information and SCD files of intelligent substations. Background technique [0002] The SCD file (SubstationConfigurationDescription (full station system configuration file)) describes the overall station configuration information of the smart substation. In the design process of the intelligent substation, the SCD file is completed by the design institute, and in the debugging process, the equipment supplier downloads the configuration information in the SCD file to each IED (Intelligent Electronic Device (Intelligent Electronic Device)). In view of the strict safety requirements of the power system, how to efficiently and reliably judge that the downloaded configuration information is consistent with the information in the SCD file is a matter of great concern to the s...

Problems solved by technology

[0004] Among them, one method is to manually copy the CRC check code of the IED configuration information and compare it with the CRC check code of the IED in the configuration file to judge the consistency. The disadvantage of this method is that there are manual links, the efficiency is low, and Increased possibility of introducing human error

[0005] Another method is to introduce a monitoring module. The module parses the CRC check code from the message uploaded by the IED and automatically compares it with the CRC check code parsed from the SCD file, so as to automatically judge whether it is consistent. The disadvantage of this method It is necessary to build a real-time monitoring module, which is cumbersome and not convenient to operate during maintenance, and needs to introduce links such as communication and message analysis, which is expensive
