[0045] image 3 It is a schematic flow chart of the automatic closed-loop testing method of the present invention. Such as image 3 As shown, the present invention also provides a kind of automatic closed-loop testing method, is applied to automatic closed-loop testing system, and described method comprises:

[0046] Compile the preset number of remote signal displacement data as test data and store it in the test sample library;

[0047] Import the remote signal displacement data during the test, and apply it to the input port of the system and equipment under test according to the corresponding data format;

[0048] Receive the output of the system and equipment under test, analyze the message and record the remote signaling status, change times and change time, and obtain the analysis results;

[0049] The analysis result is compared with the original data in the test sample library to obtain the test result.

[0050] Preferably, different excitation signals are output fo...

Embodiment 3

[0059] Such as Figure 4 As shown, according to another aspect of the present invention, the present invention also provides an automatic closed-loop test system, the system includes a processor and a memory, the memory stores computer-executable instructions, and when the computer-executable instructions are processed Automatic closed-loop test method is realized when the device is executed.

Abstract

The invention relates to an automatic closed-loop test system and method. The system comprises a message analysis module which is used for carrying out the time packaging and data message splitting ofa signal, analyzing the message data according to different message protocols, analyzing the correctness and delay characteristics of a whole remote signaling test through combining with the calibration time, and feeding a result back to a system management module and the system management module which is used for analyzing a model file, displaying a user interface, configuring and storing test parameters and test samples, monitoring and checking the start-stop operation in the test process, the test process and the test result for managment, and receiving the result fed back by the message analysis module. Through the automatic closed-loop test of the remote signaling data flow of the intelligent substation, the automatic test is realized, and the manpower and material resource costs aresaved.

Description

technical field [0001] The invention belongs to the field of automatic detection of intelligent substations, and in particular relates to an automatic closed-loop test system and method. Background technique [0002] The intelligent substation monitoring system is from data collection to data processing, from control command to control output, and the data stream composed of these messages is transmitted between each system and IED. If it is only for a single device to test, it is difficult to find the system However, the testing method oriented to data flow is more scientific and reasonable. [0003] The main business of a smart substation is a causal event from incentive to response. Cause and effect are in a one-to-one relationship. The result can be determined by grasping the cause. If there is some difference between the actual result and the expected result, it will explain the cause and effect. An anomaly has arisen in the relationship - the testing activity is a pro...
