The DMA-1000 Substation Monitoring Information Full-Link Acceptance System is a monitoring information acceptance tool developed based on the IEC61850 and IEC104 protocols. It is applicable to smart substations or conventional substations with IEC61850 communication, and can be used in newly-built substations of various voltage levels as well as reconstruction and expansion projects. The system features synchronous acceptance of remote terminal units and monitoring backends, and realizes intelligent or automatic point-to-point verification of monitoring information at both substation and master station ends. Automated acceptance greatly improves the efficiency of monitoring information acceptance for smart substations, enables full-loop and full-information acceptance of monitoring information, reduces work intensity and shortens commissioning periods.

Field Application

A 220kV smart substation has been put into operation. On-site, protection setting verification and test joint commissioning were completed through point list-based point-to-point verification. It was verified that the point-to-point device controls the output of the relay protection tester, the tester is connected to the protection device to automatically generate test schemes, automatic testing is set, and the line distance protection outlet test is completed.

Test Process

1. Import the point list into the point-to-point device to display filtered test points for protection tests; import the SCD file to display the models and names of all IED devices in the substation.
2. Conduct a full-substation scan to complete keyword matching between the point list and the SCD file; manually match the unmatched test points if necessary.
3. Generate test schemes and classify all test items of the same IED device.
4. Start the point-to-point test for the tested IED device, and control the relay protection device to conduct tests in the sequence of the generated test schemes.
5. Automatically judge whether the test item is completed based on the collected IEC104 messages of the remote terminal unit, and finally generate a test report.
