Description

Technical Field

[0001] This invention relates to the field of secondary circuit model configuration file verification for intelligent substations, specifically to a method and system for verifying the consistency of secondary circuit models based on SPD files and SPCD files. Background Technology

[0002] As a crucial component of the power grid, the quality of substation secondary circuit design and operation / maintenance directly impacts the safety and stability of the power system. In recent years, with the expansion of power system capacity and the increase in automation, the design complexity of substation secondary systems has significantly increased, and secondary circuit models have undergone frequent changes and modifications. This has led to errors in the secondary circuit models that do not match reality, severely affecting the accuracy of secondary circuit wiring and the efficiency of substation operation and maintenance. Based on this situation, there is an urgent need to research verification techniques for secondary circuit model data to improve the completeness and accuracy of the data, support intelligent operation and maintenance processes, and ensure the safe and stable operation of the power grid.

[0003] Currently, the relevant standards for secondary circuit models are "GB / T 37755-2019 Technical Specification for Fiber Optic Circuit Modeling and Coding in Intelligent Substations" and "DL-T2765-2024 Logic Model Specification for Transmission and Transformation Engineering." GB / T 37755-2019 defines the generation of SPCD files, which contain fiber optic circuit modeling information for secondary circuits, while DL-T2765-2024 defines the generation of SPD files, which also contain fiber optic circuit modeling information for secondary circuits. Therefore, redundant data between SPD and SPCD files can be used to perform consistency verification of the secondary circuit model, checking for errors in the files and preventing accidents. However, the content of SPD and SPCD files is quite complex, containing fiber optic secondary circuit modeling data for the entire substation, resulting in a large data volume. Manual verification is not only labor-intensive but also inefficient and prone to errors, seriously affecting the accuracy of secondary circuit wiring and the efficiency of substation operation and maintenance.
