Embodiment Construction

[0051] The present invention will be further described below in conjunction with the accompanying drawings.

[0052] The relay protection device automatic inspection method of the present embodiment consists of figure 1 The system realization composed of client software module, interface link library and tester is shown.

[0053]The client module is installed on the computer used by the staff in the field, and provides the user interface to maintain the setting value, send the operation and view the data. When using the automatic inspection function, the client software converts the parameters and instructions set by the user into the variable values ​​in the test script.

[0054] The interface link library is installed on the same computer for calling by the client software. The interface link library is matched with the tester, and the client module selects and loads the corresponding link library interface implementation according to the model of the tester. The client s...

Abstract

The invention discloses automatic checking system and method of a relaying protection device, comprising a tester. The test is connected with the relaying protection device to form an electric loop and is connected with a client terminal working station through network. The invention is characterized in that the client terminal working station is internally provided with a client terminal module and an interface linking library, wherein the client terminal module provides all user interfaces and scripts used for automatic test; the relaying protection system tester receives the test scripts, carries out the real test on the relaying protection device, and returns data according to the requirement of the scripts; and the interface linking library is a definition standard between the client terminal module and the relaying protection device tester and is also a data transmission channel in execution. By defining a standardized interface standard and realizing interface function, the invention enables user terminal software to control the relaying protection device tester through network and carry out test operation according to methods and procedures described in the scripts, thereby lowering the requirement on personnel, simplifying the working process and uniforming data forms.

Description

technical field [0001] The invention relates to an automatic inspection system for a relay protection device, which is used for controlling a relay protection tester to automatically complete a standardized inspection of the protection device and obtain standardized result data. Background technique [0002] Existing inspections of protection devices generally use manual methods, that is, use a general-purpose relay protection tester to simulate fault conditions to set output electrical parameters, monitor the action of protection devices, and verify whether the protection functions and fixed value settings are correct. , and then record the inspection results in the commissioning report. [0003] There are some deficiencies in this existing inspection method: [0004] 1) Excessive reliance on the technical capabilities of individual staff. On-site staff must fully understand a specific function to be inspected, and calculate its action characteristics according to the der...
