Research on automatic verification technology of virtual circuit in intelligent substation based on standard terminal library

Inhalt:
Intelligent substations are based on virtual circuits for signal transmission between devices, which is very important to the operation of the substation. Before the substation is put into operation, the SCD file needs to be checked for virtual circuits. This paper proposes an automatic verification method for virtual circuit of intelligent substation based on standard terminal library. The standard terminal library is established based on Levenshtein distance fuzzy matching algorithm to solve the problem of non-standard substation configuration file model. It also introduces Word2Vector similarity to improve the editing operation weight setting to improve the accuracy of the algorithm. The verification template is established based on the standard terminal library and the SCD file that has passed the review to realize the automatic verification of the virtual circuit. And the feasibility of the proposed method is verified by an example.
