Studies And Applications Of Communication System Architecture With Standard Oriented To Smart Grid

Standardization of construction is the key factor in the realization of intelligent communications, in the past different power system communications device applications of equipment manufacturers require proprietary interface software support. With the growing demand for diversified grid communication applications, more and more independent communication equipments of the power system are put into the macro-environment, and these devices are lack of uniform standards for data sharing and information interaction on the platform, so the co-ordination between them become isolated and disorder. All parties of the power system concern and exchange the information in different ways makes the construction and operation of the system are troubled by the legacy systems, private agreements, and special interfaces. To reduce the adverse effects of heterogeneity for information technology standards in power system and make communication architecture meet the needs of the actual operation in intelligent power grid, this paper analyzes IEC61850 and IEC61970 standards for the expansion of information technology applications based on practical intelligent requirement configuration in an integrated energy and communications infrastructure. The main contents in the research are as follows:Against the limitations of original computing application service model, a computing application architecture with Enterprise Computing Service Bus and function modules is proposed. It points out that the integrated open system based on the CIM standard is an important mode in enterprise information services, and starting with specific construction of Web Service in the bus, this paper describes the information computing integration process of various heterogeneous application systems in the ESB, then it demonstrates the specific role of Web component adapter in dealing with message handling and analyzes the implementation of a series of questions, such as the model management, data sharing, and visualization applications of function modules.To adapt to the needs of intelligent communication system, in addition to the formation of information flow mechanisms within the enterprise, in the external applications of the enterprise, such as standard practice or standard integration among the digital substation and their own communication center, need much more to develop a viable and effective solutions. In the process of substation information planning process, how to coordinate data processing of process level, bay level and station level and make the equipment of substation and dispatching communication center cover an information sharing model is one key point in this paper. Moreover, an interactive geographic information visualization based on power network model is introduced. Based on the study of CIM/XML model file as grid geographical data carrier, associated component classes is used to express the actual property of power equipment, and through designing external operational environment of ODE interface, the gird topological relations are created as well graphical element is depicted and displayed, as well as a construction of power system description and its information display based on communication standard of CIM specification.
