IEC 61850 general modeling method

Abstract

The invention discloses an IEC 61850 general modeling method and belongs to the technical field of electric power automation. The IEC 61850 general modeling method is used for solving the problem that an existing modeling method for a specific device can not be applied to modeling of other devices and the problem that the existing modeling software can not meet the new modeling requirement. According to the IEC 61850 general modeling method, as a modeling rule, a data rule and an abstract modeling port are designed, the modeling port is separated from the data so as to achieve configurable general modeling oriented to the rules. By the adoption of the IEC 61850 general modeling method, repeated development of modeling software oriented to a specific device is avoided, cost is reduced, the new modeling requirement can be rapidly met, product quality and engineering level are improved and unifying of modeling and popularization of the IEC 61850 technology are facilitated.

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 IEC TC57. 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 power utility automation. Its application scope has exceeded Substations will be widely used in smart grids. 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-based comm...

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
