Research On Standard Model Transformation And Conformance Verification Method Of Smart Power Distribution And Utilization System Interface Adapter

As an important link between the power grid and the user, the distribution network involves with a number of basic information platform, business platform and advanced application, contains numerous and complex interactive business across systems with a demand for data sharing and interoperability. Bus integration method is used to deal with this kind of multi-source information exchange and extract. It can decouple the business client and service side as to avoid the problem of tight coupling, high complexity and high maintenance cost caused by traditional way of end-to-end interaction. The widely existing heterogeneous systems do not have direct access to bus in actual application, so the heterogeneous system need to standardize the data model and service invocation through the adapter in order to realize the information interaction of multi-source system under bus mode. Based on the goal of intelligent information exchange and interoperability, this paper, from the process of solving system interoperability model semantic inconsistencies and the standardization of enterprise integration bus semantic, carried out the research work of intelligent interface adapter model transformation and the conformance test.Beginning with the introduction of basic skills and conceptions involved in the process of system integration and interoperability, this paper puts forward bus integration architecture of system and discusses the main functions and structure features of the adapter. The adapter model transformation method with the standard of CIM is studied then. The model transformation mechanism is also put forward. On the one hand, the method of CIM modeling, description and storage of the distribution power system is discussed, and several typical CIM model of distribution system equipment is enumerated. On the other hand, the configuration process, storage and discovery mechanism of the model mapping rules is studied based on the analysis of model transformation rule between the application system and the CIM and studies, then the basic process of computer model transformations is proposed. As to the consistency problem for bus model semantic, the grammar, content and semantic verification of models information using RDFS is proposed after model transformation. And the process of the model consistency verification is discussed.On the basis of theoretical research, this paper finally gives the basic principle of design of adapter software, proposes the hierarchical structure design model for interface adapter software, and specifies the function of module involved in each structure layer. Each module function and the software implementation in model transformation and consistency verification are emphatically discussed, and the transformer model is illustrated as a example of model conversion and validation. As a foundation for implementation of intelligent information interoperability of distribution system, the research of standardization and normalization of information model will greatly promote the progress of the intelligent construction and system integration technology of distribution.
