Digitized protective device automatic test control system and control method thereof

Abstract

The invention discloses a digitized protective device automatic test control system and a control method thereof, and belongs to the technical field of intelligent transformer substation tests and verification. The system comprises a test analysis module, a parameter management module, a 61850 client side module, a test case management module, a test control module, a report output module and a configuration library module. Test cases are generated automatically according to definite value information, a test case library is established aiming at digitized protective device types, definite values of the digitized protective device are downloaded to the digitized protective device automatically, the operation that a relay protection testing device is controlled to add and control messages for the digitized protective device is completed automatically, and test reports are output automatically. According to the digitized protective device automatic test control system and the control method thereof, for the application scenarios that secondary relay protective factories complete leave-factory test fast, electric power companies check and accept protective devices and intelligent transformer substations carry out on-site equipment tests, repeated and tedious work of workers can be reduced greatly, and working efficiency can be improved.

Description

technical field [0001] The invention relates to an automatic test control system of a digital protection device and a control method thereof, and belongs to the technical field of test and verification of intelligent substations. Background technique [0002] From 2011 to 2015, my country's smart grid entered the stage of comprehensive construction, and infrastructure substations were constructed according to the standards of smart substations. With the promotion of smart substations nationwide, more and more attention has been paid to how to test the protection logic of digital protection devices more efficiently and accurately. Application scenarios such as factory inspection of secondary relay protection manufacturers, acceptance of protection devices by power companies, and on-site device testing of smart substations all require testing of digital protection logic. [0003] Although the traditional testing of digital protection devices with digital relay protection test...

Problems solved by technology

[0003] Although the traditional testing of digital protection devices with digital relay protection testers can complete the test of the protection logic of digital protection devices, it cannot automatically test digital protection devices. It requires manual writing of test cases. Set the value of each protection device (even if it is a different device of the same type), manually operate the digital protection tester, and compare the test results manually, which has the disadvantages of low test efficiency, complicated work, and the inability to effectively inherit and utilize test cases
