| Abstract: |
| In order to solve the problem of visual display, loop monitoring and diagnosis of secondary virtual circuit in operation and maintenance of intelligent substation, the virtual circuit comprehensive monitoring technology system of intelligent substation is constructed. The configuration rules of the soft plate and the virtual circuit are designed, and the state monitoring of the soft plate object is taken as part of the virtual circuit detection. It is proposed to store physical fiber loop based on adjacency list, and realize the physical link relationship of process layer equipment by adopting depth first search algorithm. Meanwhile, the fault area are diagnosed and located based on depth search and fault reasoning algorithms, which satisfies the new application demand of secondary equipment operation and maintenance in intelligent substation. |
