Relay protection device tester, automatic test method and device

Abstract

The invention relates to a relay protection device tester, an automatic test method and a device, and belongs to the technical field of relay protection automatic test. Wherein the method comprises the following steps: when starting a test case, read the relevant initial state information of the device under test, and compare the test case with the read initial state information of the device under test, if different, the Modify the initial state information to the initial state information corresponding to the test case; detect whether the initial state information of the device under test has been modified successfully, and if not, modify it again until the modification is successful or the number of modifications reaches the upper limit threshold of the number of modifications; if the modification is successful, Then carry out the test; if the modification has not been successful, it is determined that the device under test is faulty. This method performs multiple revisions in the case of unsuccessful revisions until the revision succeeds or the number of revisions reaches the upper limit threshold of the number of revisions, so as to ensure the reliability of test execution.

Description

technical field [0001] The invention relates to a relay protection device tester, an automatic test method and a device, and belongs to the technical field of relay protection automatic test. Background technique [0002] With the rapid development and wide application of computer technology, the automation technology of relay protection device testing based on computer technology has also made great progress. The current automatic relay protection system has been able to automatically read and write status information such as the pressure plate and fixed value of the relay protection device under test through the test software according to the content of the test case, and automatically control the tester to increase the amount of the relay protection device under test in a timely manner. Automatically receive the result data of the execution case of the relay protection device under test, and realize the comparison between the test expected value and the execution result d...
