Problems solved by technology

At present, the smart substation relay protection tester has initially realized the function of automatic testing, and the degree of automation has gradually increased. However, in the actual smart substation commissioning and testing process, if a certain test content is not successful, it is often difficult for testers to quickly find the problem. As a result, although the relay protection test process is basically automated, the test efficiency is often not high in the actual test process, and even the test cannot be successfully completed.

Abstract

The invention discloses a relay automation tester using secondary state detection and closed loop testing method, comprising: a testing hardware part and a testing software part wherein the testing hardware part comprises a central processing unit. The central processing unit is connected simultaneously with a data processing unit, an interruption unit, a synchronization unit, an analog output / input, a light signal output / input signal and a transformer station secondary state monitoring and diagnosing unit for fault information diagnosis. The testing software part is used to schedule the testing hardware part to measure the data, to analyze to obtain alarming information, to conduct algorithm analysis of secondary equipment monitoring and the diagnosing results and to obtain a testing report or the reason for a failed test. According to the invention, the schemes form a closed loop testing process for online fault diagnosing which makes the testing process more strict and problems uncovered and processed more quickly so as to obtain rapid testing results, and therefore, the testing efficiency is increased to a large extent.

Description

technical field [0001] The invention relates to the field of power systems, in particular to a relay automatic tester and a closed-loop test method using secondary state detection. Background technique [0002] The relay protection tester is one of the important equipment in the power system, and its reliable operation plays an important role in the safe and stable operation of the power system. In the actual production process of the relay protection tester, strict performance testing and quality monitoring are required. At present, the smart substation relay protection tester has initially realized the function of automatic testing, and the degree of automation has gradually increased. However, in the actual smart substation commissioning and testing process, if a certain test content is not successful, it is often difficult for testers to quickly find the problem. As a result, although the relay protection test process is basically automated, the test efficiency is still...
