Design And Realization Of Power System CIM Storage Model

In order to guarantee the safe,reliable and economical operation of power system,there must be an efficient power system analysis software to assist the relevant personnel to analyze the actual operation of the power grid and improve the accuracy of operation management and decision making.As the non-uniform power grid model and non-standard data access interface of the previous power system analysis software,the opening capability and expansibility are poor.Therefore,it is of great significance to develop an open,operable,and expandable grid analysis platform by using the CIM and CIS standard.The storage of power grid model is one of the core functions of the grid analysis platform.The research work is to design the information storage mode of the power grid analysis platform,which is based on the IEC61970-301 CIM standard and uses the relational database SQL Server to store the historical data and uses the memory database FastDB to store the real-time data.Both the mapping between object oriented CIM model and relational model and the storage design of CIM model in SQL Server are realized.Besides,the storage design of CIM model in FastDB are also realized,and the interface program,which is used to add,delete,modify and query the CIM data in FastDB,is written.In the end,the synchronization between the CIM memory database and the external SQL Server database is completed.The performance of the interface program is tested with an actual power grid example to verify the correctness and efficiency of the designing under the Visual Studio 2013.NET environment,which is to meet the design requirements of the server of the platform.
