Abstract:

To solve the problem of long debugging cycles in the renovation of station control layer integrated automation equipment of substations in service for more than 10 years, an automatic verification scheme is proposed. A simulation test environment is built, data migration tools and automatic comparison analysis methods are adopted, and the original old equipment is fully utilized to realize static and dynamic closed-loop verification of engineering data of new replacement equipment. The renovation efficiency and quality are greatly improved, which provides an effective technical support for the rapid reconstruction of integrated automation equipment in aged substations.

Key words: substation, station control layer, integrated automation system, equipment reconstruction, automatic verification
