Embodiment Construction

[0050] The specific embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0051] The ICD model file data type template conflict and redundancy check process is as follows: figure 1 As shown, the analysis model file extracts attribute information and connects according to certain rules. The classic MD5 hash function is used as the hash algorithm to generate the first layer hash table of the model, and then the first layer hash table corresponding to each template id The hash values ​​in are spliced ​​according to certain rules, and the MD5 hash function is used to generate the second layer hash table of the model. Conflict and redundancy checks are performed based on the template id and the second-level hash table.

[0052] First, the Xerces C++ parsing library and SAX technology parse the ICD model and extract model attribute information, mainly including:

[0053] 1), middle Elements and th...

Abstract

The present invention provides a method for checking consistency between intelligent substation ICD models. The method comprises the following steps of: 1) establishing a model structure body; 2) outputting a conflict check result; and 3) outputting a redundancy check result. According to the method provided by the present invention, inter-model conflict and redundancy check are performed between a plurality of ICD models, the check is short in time, and the check results are accurate.

Description

technical field [0001] The invention relates to a method in the field of electric power systems, in particular to a method for checking consistency between ICD models of intelligent substations. Background technique [0002] In order to deepen the standardized construction of infrastructure, strengthen the standardized management of smart substation information models, and standardize the testing requirements of information models, the State Grid Corporation of China has promulgated the enterprise standard Q / GDW11156-2014 "Smart Substation Secondary System Information Model Verification Specification" (hereinafter referred to as "Specifications") 》) to promote the standardized application of the secondary information model of smart substations, promote the standardization of secondary system information model verification, ensure the validity, integrity and consistency of the information model, and ensure the interoperability of equipment from different manufacturers.
