Abstract: Currently, the delivery of secondary curcuit designs in substations still relies on traditional drawing methods. This approach requires personnel with specialized knowledge for drawing verification and field operation and maintenance, which is not conducive to the development of digital technologies in power systems. To achieve intelligent verification of secondary circuit wiring in substations, this paper draws inspiration from the IEC61850 logical modeling approach and proposes a digital twin-based modeling scheme. Starting from the perspective of substation engineering design, the paper performs digital modeling of general layout, screen position arrangement, panel grouping scheme, and crucial wiring designs. Building on this, typical design specifications are transformed into a digital standard rule library, serving as the basis for intelligent verification. By comparing and matching object instance attribute data obtained from scanning on-site cabinet and cable QR codes, this method verifies the design product and aids in construction and later operation and maintenance. Simulation tests on a certain expansion project demonstrate that this method effectively improves the work efficiency of debugging and operation and maintenance personnel.
