Embodiment Construction

[0027] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0028] The present invention constructs a real-time database system that fully conforms to the IEC61850 model for the substation automation system adopting IEC61850, including the integrated monitoring platform of the station control layer, the background, the guarantee letter and the like.

[0029] (1) Analyze the IEC61850 model and extract the IED models of each device from the SCD file without distinguishing the signal types, such as telemetry, remote signaling, remote control, protection signals, etc.

[0030] The IEC61850 model diagram is as follows figure 1 shown.

[0031] (2) Create a real-time database XML file

[0032] The model structure of each device IED is expanded and described ...

Abstract

The invention discloses a modeling method based on an international electro technical commission (IEC) 61850 protocol and an extensive makeup language (XML) database. The method includes that (1) for a substation automatic system adopting the IEC 61850 standard, according to a whole-station security coding device (SCD) model description file, IED models of all devices in the substation are extracted; (2) the IED model structures of all the devices are unfolded and described in an XML file format and converted into a static base and an event base of an XML structure; (3) by means of the XML structure, a real-time base and an event deflection base based on the XML database are built; (4) a database API packaged with XQUERY inquiry language is used for processing the XML database. The method for describing an IEC 61850 model structure in the XML information format without distinguishing signal types is provided and developed. Information conversion and processing are achieved through the XML database, and accuracy of the models and parameters generated automatically can be ensured.

Description

[0001] technical field [0002] The invention belongs to the technical field of electric engineering, and more precisely, the invention relates to a modeling method of a real-time database inside a substation automation system based on the IEC61850 standard. Background technique [0003] 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 TC 57) of the International Electrotechnical Commission (IEC) has developed a series of standards, including the IEC 61970 standard for dispatch centers and the IEC 61850 standard for substations. By establishing a standard and open power system information model, it promotes interoperability between applications, reduces production and maintenance costs, and improves system reliability. [0004] At present, although ma...
