Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of intelligent substation operation and maintenance, and particularly relates to a business-oriented SCD model decoupling method and device and a storage medium. BACKGROUND

[0002] In an intelligent substation, SCD (Substation Configuration Description) contains complete primary equipment topology, function topology and communication topology and other information of the intelligent substation, and there is an industry specification DL / T 860-2004 Substation Communication Network and System for clearly requiring SCD modeling. The intelligent substation uses the SCD model to improve the efficiency and standardization degree of engineering configuration.

[0003] Since the SCD model file is too professional and different business configuration information is mixed together, the substation operation and maintenance or professional management personnel cannot quickly locate the information of the business concerned, and the model maintenance and control can only rely on the equipment manufacturers or system integrators, which is not conducive to substation maintenance management, professional management and supervision and the like. Meanwhile, when the substation equipment is replaced or later expanded, the model file must be changed, and the change risk is not easy to control, and the correctness of the function is often debugged and confirmed through large-scale power outage or full-station power outage, and then put into operation.

[0004] In order to improve the maintainability and usability of the SCD model, the SCD model is decoupled, the complex SCD model is decomposed into smaller and more manageable and understandable components, the coupling between different parts is reduced, and the modification and maintenance of the model are more easy.

[0005] The patent document with the publication number CN106355305A discloses a decoupling method for SCD model information section of an intelligent substation. The method obtains all interval division information of the whole station and IED information contained in each interval by analyzing the configuration content of SSD in the SCD file, and extracts the model configuration content of the IED from the SCD file to reorganize the interval BCD file according to the SCL standard format. The decoupling method is oriented to the physical decoupling of the SCD model file for the interval, and it is difficult to flexibly perform business configuration and management according to actual requirements, and the configuration data and management authority of different businesses are not classified and isolated, and there is a risk of misoperation.
