Problems solved by technology

Information such as GOOSE (GenericObject Oriented Substation Events, general object for substation events), SV (SampledValues, sampling value) and virtual terminals have been gradually integrated into the model. In the process of actual promotion and application, it is inevitable that there will be problems such as difficult analysis and inconvenient analysis and search.
[0007] Traditional detection methods are either too expensive, or the detection content is limited, and it is not easy to expand, and cannot meet the requirements of various local standards in China

Embodiment Construction

[0020] At present, all the objects needed for XML parsing have been encapsulated in the XML parser, and the parsing and verification of XML documents can be realized by calling the relevant interface in the actual application process. The detection method is also based on this idea, synchronized with the analysis, to realize the digital substation model detection method, including the following steps:

[0021] (1) Use the SCHEMA file for model normative testing issued by the IEC61850 international standard for the substation device model to realize the Schema verification of the digital substation general model file:

[0022] The validity verification of the general model file Schema of the substation (taking libxml2 as an example) is preferred, but not limited to the following steps:

[0023] Step 1: Load the model file and Xml Schema file.

[0024] Step 2: Use the SCHEMA verification module based on the XML parsing library LIBXML2 to perform SCHEMA verification on the model...

Abstract

The invention discloses a method for detecting a digitized transformer station model. In recent years, IEC61850 and digitized transformer stations are developed quickly; however, great difference exists due to different producers and different device models, which brings great difficulties and hidden troubles to debugging and running; therefore, a detection means and a method which are simple, practical, effective and comprehensive are needed. In accordance with an IEC61850 standard, the method for detecting the digitized transformer station model supports a standardized detection aiming at the domestic 'Engineering Implementation Technical Specifications of IEC61850 International Standard', and is widely applied to the model detection of digitalized and conventional IEC61850 transformer station comprehensive automatic systems, wherein the method comprises the following steps of: detecting whether an XML format is right and performing Schema verification; detecting basic unit data, namely detecting the information such as logical nodes, common data, data objects, attributes and the like; resolving and detecting a model GOOSE and four-remote information; comparing offline and online models; and detecting SCD file virtual terminals.

Description

technical field [0001] The invention is used in the digital substation of electric power system and the automation field related to IEC61850, and specifically relates to a model detection method. Background technique [0002] With the development of network technology and the improvement of substation automation level, the IEC61850 protocol has gradually solved the problems of poor communication and debugging difficulties caused by the inconsistency of protection protocols among traditional substation manufacturers, and realized the interoperability of equipment in a real sense. Realized the intercommunication and interconnection among manufacturers, and realized the unity of communication protocols. [0003] The most important information carrier to realize IEC61850 communication is the model file. Based on XML technology, IEC61850 defines a substation configuration language (SCL). The file types mainly include: ICD (IED Capability Description, IED capability description f...
