Automatic checking system and method of relaying protection device

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 clientterminal 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 to control a relay protection tester to automatically complete a standardized protection device inspection and obtain standardized result data. Background technique [0002] The current inspection of protection devices generally adopts manual methods, that is, use a relay protection tester with general functions to simulate fault conditions to set the output electrical parameters, monitor the operation of the protection device, and verify whether the protection function and the fixed value setting are correct , And then record the inspection results in the commissioning report. [0003] There are some shortcomings in this existing inspection method: [0004] 1) Over-reliance on the individual technical ability of the staff. On-site staff must fully understand a particular function to be checked, derive and calculate its action characteristics according to the ...
