Problems solved by technology

Due to the immaturity of individual smart devices, changes in design schemes, etc., the ICD version changes frequently, which in turn leads to frequent changes in the SCD, and there is no strict version control mechanism. It is necessary to ensure that the ICD is consistent with the corresponding version of the SCD file, otherwise there will be problems during system debugging. An error occurs, and in severe cases, it may even affect the stable operation of the secondary system

Embodiment Construction

[0019] The present invention is based on the ICD and SCD consistency checking method of model object semantics, such as figure 1 shown, including the following steps:

[0020] (1) Establish the RDF Schema model of ICD files and SCD files according to the IEC61850 standard Schema model (XML Schema).

[0021] The reason for establishing the corresponding RDF Schema model is that there is a close dependency between the nodes in the ICD file, which is suitable for carrying by an object-oriented data model. In this embodiment, the RDF Schema model adopts the model RDF Schema mentioned in the Chinese patent "Graphic and RDF Model Construction Method for Smart Substation Design" with application number 201110227408.9.

[0022] The RDF Schema model objectification adopts the same form as the IEC61850 standard Schema model, uses RDF to describe the IEC61850 standard Schema model, and gives the RDF Schema of the IEC61850 standard Schema model; the node intelligent device IED, the acces...

Abstract

The invention relates to an ICD and SCD consistency calibration method based on model objectification semantics. The ICD and SCD consistency calibration method comprises the following steps that first, RDFSchema models of an ICD file and an SCD file are established according to an IEC 61850 standard Schema model; second, RDF objectification is conducted, all nodes in the ICD file and the SCD file of the corresponding version are established to be object-oriented RDF data objection instances, the dependency relationship among all the nodes in the ICD file and the SCD file is also established into specific RDF data object association, and all the nodes in the ICD file and the SCD file are stored in an object-oriented data model in an RDF data object mode; third, consistency calibration is conducted, objects corresponding to the ICD are sought in RDF objects corresponding to the SCD, and consistency calibration is conducted; fourth, a calibration report is obtained. The ICD and SCD consistency calibration is convenient to detect, improves work efficiency, and saves human cost.

Description

technical field [0001] The invention relates to a method for checking consistency between ICD and SCD based on model object semantics. Background technique [0002] Compared with conventional substations, the secondary system of smart substations adopts the latest communication technology and information processing technology. The deployment of functions and the communication relationship between functions must be described and carried by configuration data (in the SCL format of IEC61850). Configuration data is also the core information of common concern in all aspects of the smart grid. The IEC61850 standard stipulates the ability to use ICD files to describe smart devices, and multiple ICD files are integrated to form a total station system configuration file SCD. Due to the immaturity of individual smart devices, changes in design schemes, etc., the ICD version changes frequently, which in turn leads to frequent changes in the SCD, and there is no strict version control ...
