Problems solved by technology

[0003] When using an SCL file, it needs to be parsed first. At present, various applications often only regard SCL files as ordinary XML format files, adopt conventional parsing methods such as DOM and SAX, and do not fully apply the object-oriented description method of SCL files. It leads to low parsing efficiency, which affects the performance or user experience of the application to a certain extent

Embodiment Construction

[0035] The present invention will be further described below in conjunction with the drawings. The following embodiments are only used to illustrate the technical solutions of the present invention more clearly, and cannot be used to limit the protection scope of the present invention.

[0036] Such as figure 1 As shown, for the current intelligent substation modeled by the IEC 61850 standard, various configuration files in the station are described in the SCL language of IEC61850-6. When the application analyzes the SCL file, the object-oriented modeling feature of the SCL file is fully utilized: ( 1) The logical node, data object, and data attribute under the IED label are the instantiation of the logical node class, data object class, and data attribute class defined in the data template; (2) the logical node class, data object class and data attribute There is a hierarchical containment relationship between classes. Each logical node class contains multiple data objects, and ...

Abstract

The present invention discloses a fast analytic method of smart substation SCL files, comprising the following steps of (1) analyzing an SCL file data template; and (2) analyzing an IED instance. According to the fast analytic method, efficiency and speed of applications can be improved, requirements of the applications on host machine hardware configuration can be reduced, and engineering cost is also reduced to a certain extent. The fast analytic method can be used for smart substation configuration files using IEC 61850-6 SCL language modeling, such as ICD files, SCD files and CID files, and has universal adaptability and certain promotion significance.

Description

Technical field [0001] The invention relates to a method for quickly analyzing SCL files of an intelligent substation, and belongs to the technical field of power system automation. Background technique [0002] In the current process of construction of smart substations, the IEC 61850 series of standards have become the equipment in smart substations due to the use of object-oriented modeling technology and the openness, advancement and integrity of "one world, one technology, one standard" The only actual standard for modeling and communication provides a convenient way for intelligent electronic devices (IEDs) from different manufacturers to achieve interoperability and seamless system integration. With the wide and in-depth application of the IEC 61850 standard in smart substations, various configuration files in the station are basically modeled in the SCL language specified by IEC 61850-6, such as the device capability description file (ICD) of each smart electronic device....
