Graphical SSD (System Specification Description) configuration method based on IED (Intelligent Electronic Device) template

Abstract

The invention discloses a graphical SSD (System Specification Description) configuration method based on an IED (Intelligent Electronic Device) template. The method aims at a situation that current smart substations all adopt an IEC61850 (International Electrotechnical Commission) model structure or a similar tree form hierarchical structure as the data structures in an instation database and also have a graphical CID (configured IED description) tool. The method comprises the following steps: firstly, drawing primary equipment in the SSD and the electrical connection relationship of the primary equipment; then, in virtue of the primitive function of the graphical tool, drawing secondary equipment primitives in the substation; associating the secondary equipment primitives with the corresponding models of the secondary equipment primitives to form an IED template so as to form an IED template library; and finally, carrying out the primary and secondary association of the SSD in a form of dragging the IED template directly on the primary equipment of the SSD and the electrical connection graph of the primary equipment. The method is convenient and visual in configuration and can improve CID efficiency.

Description

technical field [0001] The invention relates to the technical field of electric power automation, in particular to a graphical SSD configuration method based on an IED template. Background technique [0002] IED (Intelligent electronic device), intelligent electronic device. The IEDs in the substation adopt a unified protocol to exchange information through the network. IEC 61850 (series of international standards for communication networks and systems in substations) models most of the common real equipment and equipment components, and these models define common data formats, identifiers, behavior and controls. To integrate an IED into a substation automation system, it is necessary to use the substation configuration language stipulated in the IEC 61850 standard to describe the IED, that is, to configure, and the configuration tool is used at this time. The main tasks of the configuration tool are: generate initial function description files (ICD files) of various IEDs ...

AI Technical Summary

Problems solved by technology

[0004] However, compared with other configuration files such as ICD files and SCD files, SSD files are popularized later and have fewer applications. At present, most smart substation configuration tools either do not configure SSD file configuration functions at all, or provide simple and inflexible configuration methods. Such as manual editing, step-by-step increase method according to the schema file, etc., the user experience is poor, the project configuration efficiency is low, and the project cost is increased to a certain extent
