Embodiment 1

[0019] see figure 1 As shown, a model conversion method from IEC61850 to 61970 includes the following steps:

[0020] Step S1, establishing a memory data model according to the IEC61850 SCL model.

[0021] As a preferred embodiment, the above process may specifically include: generating an in-memory database schema according to the XML Schema file definition of the IEC61850SCL standard, and establishing an in-memory data model by reading the SCL language. The IEC61850 standard itself is a constantly evolving standard, and its SCL language itself is also developing. The SCL memory model building technology adopted in the present invention can be based on the XMLSchema file of the SCL standard used (SCL XMLSchema file is a group of documents released together with the SCL standard. file with the suffix xsd) to establish an in-memory database model, which will not be refactored due to SCL changes, and can automatically adapt to new standards and expand the loading of standard mo...

Embodiment 2

[0056] Corresponding to the above-mentioned model conversion method from IEC61850 to 61970, the present invention also provides a model conversion device from IEC61850 to 61970, such as figure 2 shown, including:

[0057] The memory data model building module is used to build the memory data model according to the IEC61850SCL model;

[0058] A topology model conversion module, configured to convert the hierarchical structure in the SCL primary model into an IEC61970CIM topology model according to the memory data model;

[0059] The secondary model conversion module is used to convert the description language according to the memory data model and the secondary rule to perform secondary model conversion.

[0060] As a better embodiment, the secondary model conversion module may include a URI redefinition module, which is used to convert all created objects to avoid conflicting URIs according to the URI conversion rules during the secondary model conversion. redefine. The sp...

Abstract

The invention provides a model transformation method of an IEC61850 to an IEC61970 and an apparatus thereof. The model transformation method comprises steps that: a memory data model is built on the basis of an IEC61850 SCL model; on the basis of the memory data model, a hierarchical structure of an SCL primary model is converted to an IEC61970CIM topology model; and a secondary model transformation is carried out on the basis of the memory data model and a secondary rule conversion description language. According to the model transformation method of the IEC61850 to the IEC61970 and the apparatus thereof provided by the invention, a model extension is carried out on the IEC61850 standard, and the problem that when the IEC61850 standard is adopted to develop electric power automation products, the SCL specification cannot fully meet model specifications required by master station automation product development is solved. Therefore, time and effort needed to add new plants and stations to an EMS are greatly reduced, and the model transformation method and the apparatus of the invention have good application prospect.

Description

technical field [0001] The invention relates to the technical field of substations, in particular to a model conversion method from IEC61850 to IEC61970 and a model conversion device from IEC61850 to IEC61970. Background technique [0002] With the continuous advancement of computer technology, communication technology and power electronics technology, the demand for information sharing and application integration in power systems is becoming more and more urgent. To this end, the 57th Technical Committee (IEC TC57) of the IEC (International Electrotechnical Commission) has formulated a series of standards, including the IEC 61970 standard for EMS (Energy Management System) in dispatch centers and the SAS for substations. (Substation Automation System) IEC 61850 standard. Trying to establish a standard and open power system information model to promote interoperability between applications, reduce production and maintenance costs, and improve system reliability. [0003] A...
