Quick configurator of electronic equipment for intelligent substation

Abstract

The invention discloses a quick configurator of electronic equipment for an intelligent substation. The quick configurator comprises a user interface module, a checkout module, an SCL (Substation Configuration Language) file analysis module and a CID (Configured IED Description) file generation module, wherein the user interface module provides a visual operation interface which can newly establish, open and browse an SCL file and edit the model nodes and the attributes of the SCL file; the checkout module diagnoses whether the structure of the SCL file violates a format specification of XML (Extensive Markup Language) or not and diagnoses whether the semantics of the SCL file correctly follows a grammar rule in an IEC64850-7-based SCL Scheme file or not; the SCL file analysis module maps the structure and the nodes of the SCL file into a memory in a tree manner through a DOM (Document Object Model) analyzer, establishes an information template class and realizes the editing of tree mapping nodes through the establishment of a one-to-one correspondence relationship of the DOM tree and the information template class; and the CID file generation module exports IED (Intelligent Electronic Device) data information in the CID file, deletes content irrelevant to IED, establishes a corresponding DOM reflection and finally generates a target CID file. The quick configurator occupies few system resources while the IED is quickly configured, and is convenient and reliable.

Description

technical field [0001] The invention relates to an electronic equipment configurator, in particular to a quick electronic equipment configurator for an intelligent substation. Background technique [0002] In recent years, the rapid development of smart substations has put forward higher requirements for substation communication networks and systems. Communication networks and systems are the basis of the Substation Automation System (SAS). One of the best ways to establish a more open and scalable communication network is to use standard communication protocols to achieve seamless communication between various devices. The IEC 61850 standard is the communication between equipment in the substation and the system requirements related to the substation automation system defined by IEC TC57. This standard provides a complete information model and substation automation system to realize monitoring, control and relay protection related services. [0003] Part 6 of the IEC 618...

Problems solved by technology

The SAX analysis method sequentially reads and processes documents in the form of data streams, which is not conducive to data modification, but it is suitable for processing XML documents with a huge system because it does not need to construct the mapping object of the entire document in memory; the DOM analysis method converts documents After being saved as a complete node tree image, the processing of XML files can be transformed into reading and writing operations on each node of the DOM tree and its attributes, which is intuitive and simple, but limited by memory space resources, it is only suitable for small-scale processing XML file
