IEC (International Electrotechnical Commission) 61850 relay protection model checking method

Abstract

The invention relates to an IEC (International Electrotechnical Commission) 61850 relay protection model checking method. As ICD (interface control document) model documents have a series of problems including data type template conflicts, mismatching of configured data sets and device design, grammar problems, incorrect formats of short addresses, inexistence of configured variable names and thelike, equipment development and project implementation schedule are seriously affected. The method comprises the following steps of: reading in ICDs, reading out application model data from the ICDs by an ICD analysis module, carrying out grammar and semantic processing on the application model data and then submitting the application model data to a checking module; providing generated check rule templates to the checking module by a rule template module; and beginning checking after obtaining the data provided by the ICD analysis module and the check rule templates provided by the rule template module and sending the check results to a document management module the checking module. The method has the beneficial effect of ensuring correctness, consistency and stability of the ICDs.

Description

technical field [0001] The invention relates to the processing of a digital substation system, in particular to an IEC61850 relay protection model verification method. Background technique [0002] The IEC61850 standard is the only international standard for substation automation systems based on network communication formulated by the International Electrotechnical Commission. This standard uses the substation configuration description language (SCL language) based on XML format to statically describe the configuration of digital substations, in which the data model and function configuration of intelligent electronic devices (IEDs) are described through ICD files. In the process of digital substation factory joint commissioning and on-site implementation, the system configuration tool needs to import the model files (ICD files) of each type of protection, measurement and control, wave recording, intelligent terminal, merging unit, etc., and configure GOOSE, SV logic connec...

AI Technical Summary

Problems solved by technology

Due to the data type template conflict in the model file, the mismatch between the configured data set and the device design, grammatical problems, the format of the short address is incorrect, and a series of problems such as the non-existence of the configured variable name, the progress of equipment development and project implementation has been seriously affected.
