EMS中公共信息模型导入/导出技术

介绍了EMS接口标准化进程，提出了采用实时数据库作为适配器, 通过XML（可扩展置标语言）文件实现EMS的公共信息模型（CIM）数据交换的方案，数据导入、导出EMS时，由该适配器完成语法和语义的两步转换。文中解决了运用实时数据库承载CIM的关键技术问题，如对多重关联的表达和对继承的处理。实现了由CIM的UML描述自动构造实时数据库，并能将XML格式的CIM数据自动导入和导出EMS。通过自操作试验验证了该方案的可行性和适应性。

Import/Export Technique Based on Common Information Model (CIM) in EMS

The standardization of the application program interface API of the energy m anagem ent system EMS is described.U sing real- time database as an adapter and with extended marked language XML ,a scheme is proposed for the im plem entation of data exchange for a comm ercial EMS based on com mon inform ation m odel CIM .This adapter converts data in two steps:semantic translation and syntax translation.The crucial technical problems of using real- tim e database to support the CIM have been solved,such as,the representation of the multiplicity of association and the handling of inheritance.The automatic generation of real- tim e database definition according to CIM based on unified m odel language UML is im plem ented.The CIM data in XML format can be automatically im ported to and exported from a comm ercial EMS.The feasibility and compatibility of this method is validated through self- operation.
