Abstract
This study addresses the challenges of disjointed virtual-physical circuits information,the absence of correlation,inefficient maintenance processes,and the loss of topological relationships in the conventional labeling management of secondary cables in smart substations.It introduces a novel virtual-physical circuit mapping technique founded on the substation physical configuration description-substation configuration description(SPCD-SCD)collaborative modeling approach.The technique involves the creation of a device port coordinate model,the establishment of multi-dimensional coding regulations,and the implementation of a"scan and view"maintenance inspection system,enabling comprehensive traceability from the optical fiber core to the virtual terminal.Field tests across 13 substations demonstrate that this method reduces cable positioning time from an average of 4.3 minutes per cable to just 0.5 minutes,achieves a 100％accuracy rate in virtual circuit validation,and lowers the operation error rate from 4％with traditional methods to 0％.The proposed technology offers a digital solution for the standardized upkeep of the secondary system in smart substations,facilitating the digital management of secondary cables throughout their entire lifecycle.It also provides technical backing for the standardized operation of smart substations,showcasing considerable engineering application potential.关键词
