Embodiment 1
[0023] Such as figure 1 As shown, the present invention comprises the relay automation tester that adopts secondary state detection, comprises tester hardware part and tester software part, and described tester hardware part comprises central processing unit, and central processing unit connects data processing unit, interruption Unit, synchronization unit, analog output / input unit, optical signal output / input unit, and substation secondary state monitoring and diagnosis unit for fault information diagnosis; the software part of the tester is used to call the data measured by the hardware part of the tester , analyze the alarm information, secondary equipment status monitoring and diagnosis results for algorithm analysis, and obtain the test report or the cause of the test failure. The central processing unit is provided with a central processing unit, and the central processing unit can be implemented by using existing commonly used processors, such as intel Core i7 series pr...
Embodiment 2
[0033] The present invention comprises the automatic closed-loop test method of the relay adopting secondary state detection, comprising the following steps:
[0034] Step A) Turn on the automatic relay tester, open the SCL configuration file on the automatic relay tester, the program automatically parses all the IED index files, and according to the SCD database description, the program will automatically search for the name corresponding to the protection device to be tested, configure the station Control layer template file. After the template configuration is completed, connect the protection device to be tested to the relay automation tester. The relay automation tester reads the parameters of the protection device. After automatically configuring the IEC61850 standard, the consistency check is completed. According to the protection device corresponding The SCD database file starts the test and automatically generates the test report of the relay protection device. At the ...
