Research on mapping method between Logical circuit and Physical circuit of Optical Fiber Loop in smart substation Based on Deep Traversal Algorithm of Graph TheoryGao Xu1,Ma Yingxin1,Tang Xiaobing2,Yu Qingguang2
After the smart substation replaces the control cable with fiber optic cable and software logic, the optical fiber loop cannot be visually visible. At present, the research in this field all over the world mainly focuses on the description method and modeling of the fiber logic circuit, and lacks research on fiber physical circuit modeling and coding. Based on the depth traversal theory of graphs, this paper proposes a new mapping method between Logical circuit and Physical circuit of Optical Fiber Loop. The scheme abstracts the node connection relationship described by the adjacency matrix through the physical circuit described by the SPCD file, and combs out the full path of the logical and physical circuits of smart substation through the depth traversal algorithm of the graph, determines the mapping relationship between the logical and physical circuits of the smart substation. It improves management and maintenance efficiency of the optical fiber loop in smart substation.#$NLKeywords: smart substation；optical fiber loop；mapping between logical circuit and physical circuit；traversal algorithm of graph theory；Visualization
