An automatic verification method of scd file virtual loop based on intermediate model file

Abstract

The invention discloses a method for automatically verifying virtual loops of SCD files based on intermediate model files. An intermediate model file library is established, a verification template library is established, an SCD file to be verified is imported, and the IED and intermediate model files in the SCD file are verified. , Verification templates for corresponding associations, virtual terminal connection relationship verification, and verification result reports are generated. The invention realizes the automatic examination of the virtual circuit of the SCD file by establishing the intermediate model file and establishing the verification template according to the approved SCD file. The verification process is simple, less time-consuming, less manpower and material resources are invested, the verification results are less affected by subjective factors, and the verification accuracy is high.

Description

technical field [0001] The invention relates to the field of reviewing virtual circuits of SCD files in intelligent substations in electric power systems, in particular to an automatic verification method for virtual circuits in SCD files based on intermediate model files, which is suitable for reviewing virtual circuits in SCD files before intelligent substations are put into operation. Background technique [0002] Smart substations use optical Ethernet to replace secondary cables in traditional substations, providing the necessary technical foundation for data sharing and equipment interoperability. A large part of the drawings of the secondary design of the smart substation have become the virtual terminal connections mapped by the system configuration description (SCD) file. The terminal and the virtual circuit reflecting the connection relationship of the virtual terminal affect the connection relationship of the secondary circuit such as tripping, closing and sampling...

AI Technical Summary

Problems solved by technology

[0004] 2) It takes a long time and requires a lot of manpower and material resources

[0005] 3) The correct rate of manual calibration is difficult to compare with the automatic calibration of software

For example, for 500kV 3 / 2 wiring, the virtual circuit connection relationship between IEDs is complicated, and the number of strings is large, so it is difficult to check each string carefully by manual verification

[0006] 4) The ICD file model and DOI and DAI descriptions are not uniformly standardized, which brings difficulties to manual review of SCD files
