IED visualization method of intelligent transformer substation SCD file

Abstract

The invention discloses an IED visualization method of an intelligent transformer substation SCD file. The method has the following steps that firstly, the SCD file is read and analyzed and needed contents in the SCD file are introduced into a program memory; a SCD analysis module parses a complete 61850 model framework out of a read-in SCL type; secondly, classification processing is performed on an IED type, and a classification method is characterized by searching an LD type in parsed IED information; carrying out determination according to an inst attribute; thirdly, overall hierarchical processing is performed on IED; finally, hierarchical visualization processing is performed on IED individual device, through the IED individual device hierarchical visualization processing, on a structural aspect, according to a station control layer, an interval layer and a process layer, graphical display is performed on logic device LD contained by each IED physical device based on the layer that the logic device LD belongs to. By using the method in the invention, good and practical visualization training can be provided for an intelligent transformer substation maintenance debugging and operation staff so that on-site training effectiveness is effectively increased.

Description

Technical field [0001] The invention relates to the field of SCD analysis of configuration files of smart substations, in particular to an IED visualization method of SCD files of smart substations. Background technique [0002] Smart substation technology is a new electric power technology that has been vigorously developed in recent years. As an important core content of smart substation technology, SCD files are very important to describe the entire configuration of smart substations. The relevant configuration information of IED equipment is included in the SCD file. For SCD files The analysis of SCD has been relatively standardized, and there are many tools that can be analyzed, but at present, except for developers, it is difficult for people involved in on-site inspection, debugging, operation, and maintenance to understand SCD files. For example, the most widely used general third-party tool xml spy, which is currently the most widely used software tool for development an...

AI Technical Summary

Problems solved by technology

[0005] 1) The existing SCD application tools for IED analysis are mainly aimed at design and development personnel, not for substation maintenance, commissioning and maintenance personnel, so it is not very pertinent and practical for smart substation maintenance and commissioning, operation and maintenance personnel

[0006] 2) The IED device information parsed by most SCD application tools is not visualized, and the parsed information is only displayed in xml format according to the 61850 model system, so the information organization is not practical enough
