Embodiment Construction

[0028] The implementation of the present invention is as follows: an automatic inspection system is composed of a relay protection tester and field operation software, both of which use the script following the description method as an interface; XATEL (eXtensible Auto Test Execution Language, extensible Auto Test Execution Language) based on the XML1.0 specification is used Automatic test execution language) syntax to write test scripts, describing the complete automatic inspection process, parameters and other information; the tester parses and executes the script process to complete the inspection work.

[0029] The test script and XATEL language not only carry the professional knowledge of relay protection, but also exist as the interface between the client and the tester, so as to realize the loose coupling between the protection device and the tester. XATEL syntax, as the technical core of the automatic inspection description method for the entire relay protection device,...

Abstract

The invention discloses a description method of the automatic test of a relay protection device. An automatic test system is comprised of a relay protection tester and in-situ operation software, which use scripts in accordance with the description method as interfaces and complete automatic test function by analyzing and executing the scripts. The method is characterized in that the description method uses the scripts as carriers and follows the following XATEL grammars: a test process grammar that describes a test method and parameters, which are used in an automatic test process, and is used in a control tester to perform an automatic test; a result data grammar which describes automatic test result data and intermediate state information in the test process and is used in the tester for feeding back information in and after the test process; and an expression grammar which describes dynamic data algorithms uses in the test. The method can perform automation test in any tester supporting the grammar standards by using only one script in order to test the same protection function and realizes the standardization and normalization of the test process.

Description

technical field [0001] The invention relates to a description method for automatic inspection of relay protection devices. At the professional level of relay protection, the process, parameters, algorithms, execution status, data results and other information of automatic inspection are fully described in the form of scripts, which are used to control relay protection testers Automatically complete standardized protective device inspection and obtain standardized result data. Background technique [0002] In the existing technical field of automatic inspection of protective devices, only some tester manufacturers have developed software for automatic inspection functions of their own products, but the technologies and interface standards used are different. [0003] Existing automatic inspection methods have some deficiencies. [0004] The current automatic inspection software, its test process and data definition are developed according to their own understanding. For the...
