Automatic test system and method for transformer substation measurement and control device

Abstract

The invention provides an automatic test system and method for a transformer substation measurement and control device. The system comprises a test background server, an exchanger, a network tester, an intelligent tester, a three-phase standard meter, a controllable power source and a GPS clock module. The data exchanging is respectively carried out between the network tester and the test background server, between the intelligent tester and the test background server, between the three-phase standard meter and the test background server and between the controllable power source and the test background server through the exchanger, the test background server is in communication with the measurement and control device through the network protocol, the controllable power source is controlled to supply electricity to the measurement and control device, and time synchronism between the test background server and the measurement and control device is achieved through a GPS clock module. According to the automatic test system and method for the transformer substation measurement and control device, a test task can be automatically generated, detection steps can be automatically executed, detection reports can be automatically generated, the interference of artificial factors is reduced, the test randomness is removed, testing efficiency and testing reliability are improved, testing repeatability is achieved, the traceability of testing work is guaranteed, and the reliability and consistency of the test result are guaranteed.

Description

technical field [0001] The invention belongs to the technical field of automatic equipment testing, and in particular relates to an automatic testing system and method for substation measurement and control equipment. Background technique [0002] At present, with the development of smart grid scheduling automation and smart substation construction, many scientific research institutes and universities at home and abroad have carried out related smart substation experiments and testing technology research work, but there are few tests on the grid dispatching master station automation system. Some test instrument manufacturers at home and abroad have begun to develop secondary equipment testers such as intelligent substation relay protection. The power system test device developed by OMICRON provides support for IEC61850 in versions above v2.22. Domestic Zhongyuan Huadian, Bodian, Guangfuhui and other protection tester manufacturers have also carried out the research and deve...

AI Technical Summary

Problems solved by technology

Domestic Zhongyuan Huadian, Bodian, Guangfuhui and other protection tester manufacturers have also carried out the research and development of intelligent substation protection testers, but at present, there is no comprehensive inspection platform capable of comprehensive inspection of dispatching automation and substation automation systems at home and abroad. The research on the automatic test technology of substation measurement and control equipment has not been fully developed, and no complete papers on this technology can be found.

[0003] With the development of power automation technology, many new products of substation automation system are put into use and upgraded every year, and testing tools for substation automation system and various application functions are needed, but there is no automated test for substation measurement and control equipment in the market Tools, especially the lack of automatic detection methods for substation measurement and control equipment, all tests are basically still in the manual test stage, the degree of automation is not high, the test methods and test instruments are relatively backward, the standardization of testing, closed-loop testing, and testing reports The standardization of the test process, the transparency of the test process, and the scalability of the test all have great deficiencies.
