Problems solved by technology

Such a test method is very inefficient. Each test module needs to manually adjust the parameters of the tester. Each test case cannot be reused or expanded, and cannot meet the needs of relay protection and control device testing.
[0003] For example, the overcurrent protection function is applied in the protection of lines, transformers, busbars, etc., and each protection often has multi-stage and multi-time overcurrent protection functions. It takes a lot of manpower and time to modify the mapping relationship between the relay protection tester and the different overcurrent settings in the protection device

Embodiment Construction

[0017] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0018] like figure 1 Shown, be the instantiation method of object-oriented relay protection test case template of the present invention, comprise the steps:

[0019] Step 1: According to the realization principle of the relay protection and control device under test, adopt the object-oriented method to abstract the protection function test with the same test method into a test case template, such as overcurrent elements in transformer protection, line protection and busbar protection , which can be abstracted into a unified overcurrent protection test case template.

[0020] Open data interface and batch enumeration interface of the test case template: the data interface is an external access ...

Abstract

The invention discloses an object-oriented relay protection test case template instantiation method. The method includes the following steps that an object-oriented method is adopted, protection function tests with the same test method are abstracted to a test case template, and the test case template opens a data interface and a batch enumeration interface; a device data model of an object to be tested is analyzed, all protection elements of the object to the tested are parsed, a mapping relation between the data interface of the test case template and the protection element information of the object to be tested and a mapping relation between the batch enumeration interface and the protection element information of the object to be tested are established; the test case template is instantiated according to the mapping relation, and a specific test case instance is generated. By means of the method, the test case development process of a relay protection and control device is simplified, automatic test of the relay protection and control device is facilitated, and the test control and maintenance are facilitated.

Description

technical field [0001] The invention relates to the technical field of power system automation, in particular to an object-oriented instantiation method of a relay protection test case template. Background technique [0002] With the increasing development of smart grid construction, relay protection has also been greatly developed, and the test requirements for relay protection and control devices have also grown exponentially. The existing relay protection test technology is still manually controlled by testers. The current and voltage output of the relay protection tester can be tested through the simple test function provided by the relay protection tester manufacturer. Such a test method is very inefficient. Each test module needs to manually adjust the parameters of the tester. Each test case cannot be reused or expanded, and cannot meet the needs of relay protection and control device testing. [0003] For example, the overcurrent protection function is applied in th...
