Embodiment Construction

[0049] The present invention proposes a way of combining SAX and DOM to parse SCD documents, based on the mapping of data set names in SCD to telecontrol system database data types, and the predefined rules of common data class (CDC) attributes required by the system, automatically generate telecontrol System device definition. Attached below figure 1 , figure 2 , illustrate the specific implementation of the present invention:

[0050] First, use the SAX method to split the entire SCD document, extract the "Communication", "DataTypeTemplates" and "IED" tags, and cut the entire document into a Communication.xml (communication network file) document and a DataTypeTemplates.xml (data template file) document and several ied_device name.xml (device file) documents; then, each xml document is parsed in DOM mode.

[0051] Depending on the size of the SCD document, the size of the cut document is also different. The Communication.xml document describes the communication connectio...

Abstract

The invention relates to a method for generating embedded telecontrol system definitions by IEC61850 SCD files, which is characterized by comprising the following steps of segmenting an SCD document by adopting an SAX mode; analyzing segmented xml documents by adopting a DOM mode; and obtaining device information required by a telecontrol system database according to a mapping relation of data types in a device definition database of a telecontrol system and data set names in the SCD files and a predefinition rule of CDC attributes required by the telecontrol system, thereby generating the telecontrol system definitions. The SCD files are analyzed by combining the SAX mode and the DOM mode, and the system device definition database is generated by large-scale SCD files under a small resource operation environment, therefore, the invention solves the problem that the model mapping work in the traditional telecontrol system needs manual intervention to cause lower efficiency and difficult fault check.

Description

technical field [0001] The invention describes a general method for generating an embedded telecontrol system device definition from an IEC61850 SCD file, relates to the IEC61850 standard, a digital substation and a telecontrol system, and belongs to the technical field of electric power automation. Background technique [0002] In the substation automation system and dispatching application system, update the application system (such as device information management, setting value setting, etc.) according to the configuration change, and set the IED according to the application, which is very important in the entire dispatching operation and professional management work link. [0003] The configuration of the telecontrol device is usually configured by engineering personnel manually inputting the configuration information table. On the premise of ensuring system security, the configuration management of telecontrol devices can also be automatically performed through pre-de...
