Intelligent generating method of digitalized relay protection tester configuration files

Abstract

The invention discloses an intelligent generating method of digitalized relay protection tester configuration files. A testing system comprises a digitalized protective relaying device to be tested and a relay protection tester, which are connected through fibers, and comprises a host computer connected to the tester in a manner of communication. The method comprises the steps that a user adopts ahost computer software to import SCD files of a transformer substation of the protective relaying device to be tested and to import the tester configuration files of the protection device; the SCD files are analyzed by the system, obtaining virtual link information of the tested protection device, and new configuration file can be intelligently generated based on the virtual link information andthe control block configuration information in the configuration files. The invention is advantageous in that as for the test of the digitalized protective relaying device of the same type, the methodonly requires one-time correct configuration, and the following test can be realized through intelligent generation based on the former configuration files, and thereby repetitive configuration at the time of testing devices having the same type can be prevented, and testing efficiency can be improved.

Description

Technical field [0001] The invention relates to a relay protection detection method of a power system, in particular to an intelligent generation method of a configuration file of a digital relay protection tester. Background technique [0002] With the gradual development and maturity of smart substation technology, smart substations have gradually shifted from pilots to routine applications. The relay protection device in the intelligent substation uses IEC61850-9-2 sampled value message to replace the input of conventional analog voltage and current signals, and GOOSE message to replace the input and output of conventional electrical signal hard contacts. The way of message interaction realizes the digital collection and network sharing of smart device information, and at the same time improves the interoperability between smart devices. Compared with the traditional protection test, when using a digital protection relay tester to test a digital protection device, the digital...

Problems solved by technology

Use the configuration software attached to the digital relay protection tester to manually configure one by one to generate the configuration file. Not only the steps are complicated but also error-prone. Once the configuration file is wrong, the debugging of the protection function cannot be carried out at all, which seriously affects the progress of the debugging work.
