Abstract
The problem of model difference exists in the application integration based on CIM. Difference caused by diverse versions will lead to semantic conflict and inconsistency, which make data sharing impossible. To solve this problem, we need to perform research on CIM update and extension. Therefore we propose a CIM update and extension research method based on ontology. In this study the CIM update and extension are divided into four scenarios, add, delete, change and rename and corresponded algorithm are discussed. Finally, we conduct an experiment based on real model and compare the results with the ones did manually to verify this research's effectiveness and practicality.
Highlights
Standardized and open power system information is the basis for application integration
Model semantic difference will lead to semantic conflict and inconsistency which will disable the ability of data sharing among components
In order to solve the problem of model difference, we propose a CIM update and extension research method based on ontology
Summary
Standardized and open power system information is the basis for application integration. The problem of model difference exists in application integration based on CIM. On the other side, considering that manufactures always develop application integration system based on one version of CIM, the results of difference analysis can contribute to system maintenance as well as shorten the time for system updating and upgrading.
