A general modeling method for iec61850

Abstract

The invention discloses an IEC61850 general modeling method, which belongs to the technical field of electric power automation. The method of the invention is used to solve the problem that the existing specific equipment-oriented modeling method cannot be applied to other equipment modeling, and the problem that the existing modeling software cannot meet new modeling requirements. The method of the invention separates the modeling interface from the data by designing modeling rules, data rules and abstract modeling interfaces, thereby realizing rule-oriented and configurable general modeling. Through the use of this method, repeated development of specific equipment-oriented modeling software is avoided, costs are reduced, new modeling requirements can be quickly met, product quality and engineering level are improved, and it is conducive to the unification of modeling and the popularization of IEC61850 technology.

Description

technical field [0001] The invention relates to an IEC61850 modeling method, which belongs to the technical field of electric power automation. Background technique [0002] IEC61850 is a technical standard for communication networks and systems for power automation formulated by IECTC57. In the first edition, it was only used for communication in substations. In the second edition, it was changed to communication networks and systems for automation of electric utilities. Its application scope has exceeded substations. , will be widely used in smart grid. A notable feature of IEC61850 is that based on XML, the SCL model specification for information and function description of communication equipment based on IEC61850 has been formulated. At present, there are many new or derived standards based on IEC61850, which are still being formulated and released. In these standards, most of the changes focus on the extension of the model. In practical applications, each IEC61850-b...

AI Technical Summary

Problems solved by technology

The existing automatic modeling technology has improved work efficiency to a certain extent and reduced the difficulty of application, but there are two outstanding problems: (1) the modeling method for specific equipment cannot be applied to other equipment modeling; (2) Existing modeling software cannot meet new modeling requirements

[0004] Different devices have their own modeling software, and repeated development costs are high; the models generated by different modeling software are not consistent, which causes many debugging problems in practical applications

Especially when there is new equipment that needs to be modeled, or the function of existing equipment changes, or the model specification changes, the only way to meet the modeling requirements is to redevelop or modify the modeling software. There are deficiencies in consistency and lag in the application of new technologies, and the most serious problems are high development costs and low work efficiency

IEC61850 technology, especially the model, is still developing rapidly. In addition, as mentioned above, modeling and model configuration are the most frequent work content in the application. The problems of high cost and low efficiency in the existing modeling technology will become more and more serious. more prominent
