Research on Automatic Calibration Technology of Virtual Circuit in Intelligent Substation for New Power System
Facing the intelligent and high-efficiency requirements of new power systems, this paper proposes an automatic verification method for virtual circuits in smart substations based on the Levenshtein distance fuzzy matching algorithm to verify the virtual circuits in substation SCD files. Based on relay protection information specification and Levenshtein Distance fuzzy matching algorithm, a standard terminal library is established to realize the mapping between non-standard virtual terminal model and standard virtual terminal model, so as to solve the non-standard problem of substation configuration file model. And Word2Vector similarity is introduced to improve the editing operation weight setting to improve the accuracy of the algorithm. Establish verification templates based on the standard terminal library and the SCD files that have passed the review. Based on the established standardized verification template, the correctness of virtual circuit is automatically verified. And the feasibility of the proposed method is verified by an example.
