Problems solved by technology

The user has to manually read the setting value, action time, etc. from the device, and compare it with the test result of the test system, which will also bring human errors; during the test process, it is necessary to add protection functions such as switching on and off.
All tests must be manually set, and every time the configuration file is modified, the configuration parameters of the tester must be manually changed

Embodiment Construction

[0038] The concrete way that the present invention implements is as figure 1 and figure 2 shown.

[0039] figure 1 It is a structural diagram of an intelligent test system implementing the present invention. The system consists of three control chips, PPC, DSP and FPGA. The PPC is connected to the host through the network port to receive console control commands; the DSP is respectively connected to the PPC, FPGA and the expansion port, and the DSP calculates and generates data and sends it to the FPGA; the FPGA is responsible for the process layer data communication and outputs it through SV / GOOSE.

[0040] The block diagram of the test steps in this embodiment is as follows figure 2 As shown, the specific steps of the test method are as follows:

[0041] (1) Enter the IP address of the device under test to establish contact with the device under test;

[0042] (2) The intelligent test system automatically obtains the fixed value parameters and data model of the dev...

Abstract

Provided is a method for intelligently testing an intelligent substation on site. The method includes the steps of simulating station level communication, establishing a relation with a tested device, obtaining a set value parameter and a communication parameter of the tested device, automatically setting a test scheme, setting process level data parameters, outputting SV / GOOSE, receiving GOOSE information, and carrying out test on the tested device. According to the method, in the testing process, output of the SV / GOOSE is changed according to automatic setting of the test scheme; configuration of the tested device is automatically changed to enable the tested device to be capable of adapting to requirements of a specific test. A dictionary file mode is adopted in the method, so a message sent by the tested device can be accurately interpreted; after the test is finished, the result is automatically obtained from the tested device, and an analysis result is automatically given. The method changes a process level process level method of a current tester, can intelligently set test parameters and obtain the results, greatly reduces manual operation and test errors of an on-site test, improves work efficiency, and is suitable for intelligently testing the intelligent substation on site.

Description

[0001] [0002] technical field [0003] The invention relates to an on-site intelligent testing method of an intelligent substation, which belongs to the technical field of intelligent substation testing. [0004] Background technique [0005] IEC61850 transforms the complicated and troublesome on-site integration process into an offline configuration process. Various configuration files in the smart substation describe all the information in the smart substation, including: the topology of the substation equipment, the models and functions of all smart devices, and the Communication configuration between devices. During the debugging process of the smart substation, the main time is spent on generating and modifying the configuration file of the smart substation. And every time the configuration file is modified, the test must be performed again. Compared with conventional substations, the testing workload is not only not reduced, but also more cumbersome and tasks ...
