Graphic processing method for SCD (Substation Configuration Description) file

Abstract

The invention provides a graphic processing method for an SCD file meeting IEC 61850 standards. The graphic processing method for the SCD file comprises the following steps of parsing the SCD file obtained from an intelligent substation server; judging whether the SCD file accords with XML (Extensive Markup Language) file specifications and SCL (substation configuration description language) specifications of the IEC 61850 standards; generating and displaying a graphic SCD file; creating a relevance hyperlink of the graphic SCD file; performing multi-level editing operation on the graphic SCD file; reverse-parsing the graphic SCD file generation and judging whether the SCD file accords with the XML file specifications and the SCL specifications of the IEC 61850 standards; saving the generated SCD file after operation. The graphic processing method for the SCD file is a novel automation method which applies a visualization human-computer interface method and an intelligent processing technology to SCD file processing of digital substations and intelligent substations and changes original text file processing of usually more than 100 thousand lines into efficient and intelligent graphic processing.

Description

technical field [0001] The invention relates to a method in the field of electric power system and automation thereof, in particular to a graphical processing method for substation configuration description files. Background technique [0002] Digital substation is the physical basis of smart grid, and its digitalization and intelligence are the inevitable development trend of substation in the construction of smart grid. Extensive and in-depth researches have been carried out at home and abroad. Among them, digital substations and smart substations based on the international standard IEC61850 have been applied in a large number of projects at home and abroad. [0003] The substation configuration description (SCD, Substation Configuration Description) file is the basic model information file of the substation stipulated in the IEC61850 standard. It serves as a bridge for information communication between vendors, system users, system designers, and testing institutions. ...

Problems solved by technology

In the published invention patent "Smart Substation SCD Configuration File Graphical Display Method", the provided smart substation SCD configuration file graphical display method is essentially "using the network topology diagram to display the data flow relationship between the IEDs of the whole station, Users can easily view the specific content of information interaction between the target IED and the associated IED", but it does not involve graphical modification and editing of the SCD file, and what is concerned is the "data flow relationship between the IEDs of the whole station", It does not involve the processing of information other than IED in the SCD file
