摘　　要：针对变电站配置描述(SCD)文件对于物理链路信息描述的不完整,光纤物理回路模型(SPCD)文件对于物理链路描述的不直观,SCD与SPCD缺乏关联性,以及变电站运维中因缺乏虚实回路映射信息导致链路故障排查困难等问题,提出了基于SPCD的虚实链路映射方案。利用SPCD的物理链路描述信息对物理链路模型编码、扩充了SCD的物理链路模型,补充了电(光)缆编号,关键是建立了物理链路与虚链路的映射关系。为全站物理回路可视化、虚实链路映射可视化、快速故障诊断等高级应用提供了数据支撑,为交换机免配置提供了可行性方案,同时保证了SCD与SPCD的链路信息一致性。Aiming at the problem that description of physical link information in SCD file is incomplete,description of physical link information in SPCD file is non-intuitive,correlation between SCD and SPCD is little,and due to the lack of mapping information between virtual and real loops in substation operation and maintenance,link fault detection is difficult,this paper proposes a virtual-real link mapping scheme based on SPCD,includes using SPCD to code physical link,extending physical link model to SCD,supplying the electrical(optical)link model to SCD,and constructing the mapping between virtual link and real link.It provides data support for advanced applications such as full-site physical loop visualization,virtual-real link mapping visualization and fast fault diagnosis,provides a feasible scheme for switch configuration-free,at the same time,ensures the consistency of link information between SCD and SPCD.
