Research Of Server Model Based On Transmission And Distribution Network Analysis Platform

Transmission and distribution system is an important part of power system.Analysis software of transmission and distribution system have a wide range of applications in the power grid planning,operation and research.It can make simulation,calculation and simulation on transmission and distribution system,and is an important tool in promoting the development of power system.Analysis software of transmission and distribution system has shortcomings,such as a unified data model,communication interface short of specification.So it has a vital role on transmission and distribution system safety, high quality and economic operation to build an open interactive transmission and distribution network analysis platform.International Electrotechnical Commission set IEC61970 standard including the Common Information Model(CIM) and the Component Interface Specifications(CIS).It provides the basis for solving different manufacturer application system connectivity and achieving software "plug and play" in heterogeneous environment.And it ensures maintainability, extensibility and openness to the transmission and distribution network analysis platform.In this paper, we first study the characteristics of Common Information Model,Analyze the differences between CIM object model and relational database tables,give the mapping mechanism from object-oriented model to relation data model,complete the object model mapping in a relational database SQL Server 2008 and memory database FastDB.Secondly,we design and realize the database standard access interface of“Add Delete Update Select”and the synchronous component between SQL Server database and FastDB database,based on the design idea of Factory Method.Finally,we design a prototype system and write a software prototype program using C# language in Visual Studio 2013 integration environment,test the prototype program through the actual system,validate the validity and feasibility of CIM mapping mechanism and database access interface based on transmission and distribution network analysis platform.
