Embodiment 1

[0039] Such as Figure 1-9 Shown: a static mode test and dynamic mode test method for relay protection based on a unified hardware platform, including the following steps:

[0040] The background computer installs dynamic model test software and static model test software to complete the establishment of models and test cases, background control, and test result recording functions. The background test software communicates with the computing unit through the switch, and the computing unit is responsible for test command processing and model calculation. The intelligent interface and the relay protection device realize the interaction of analog quantity, switching quantity, SV and GOOSE. After the calculation unit obtains the test result, it returns it to the background software for processing and presents it to the tester for viewing.

[0041] According to an embodiment of the present invention, such as Figure 2-4 as shown,

[0042] The implementation method of the static ...

Abstract

The invention provides a relay protection static model test and dynamic model test method based on a unified hardware platform, which comprises the steps that dynamic model test software and static model test software are installed in a background computer, the functions of model and test case establishment, background control and test result recording are completed, the background test software is communicated with a calculation unit through a switch, the calculation unit is responsible for test command processing and model calculation and realizes the interaction of analog quantity, switching quantity, SV and GOOSE with the relay protection device through an intelligent interface, and the calculation unit obtains a test result, returns the test result to background software for processing and presents the test result to testers for checking. According to the method, the hardware platform not only can execute the equivalent model code of a power system, but also can execute a test command generated by a static model test case script.

Description

technical field [0001] The invention relates to the technical field of relay protection device testing, in particular to a static mode test and a dynamic mode test method for relay protection based on a unified hardware platform. Background technique [0002] Power system secondary control and protection equipment needs to undergo strict static and dynamic model tests before R&D, delivery, grid connection and operation to ensure that the functions and performance meet the requirements of relevant standards. At present, the static model test and the dynamic model test are mainly realized through related special test equipment. Static mode test equipment mainly includes test equipment produced by manufacturers such as Omicron, Onlly, Bodian, and Himile. This type of test equipment mainly outputs specific analog, switching or digital quantities through static output, state sequence, and gradient. Then realize the test of the basic performance of the relay protection device. T...
