摘　　要：基于CIM的电网静态拓扑模型是电网高级分析应用的数据基础。IEC 61970标准以资源描述框架(RDF)作为拓扑模型的表达方式,IEC 61968标准虽予以沿用,但同时提出使用可扩展标记语言模式定义(XSD)作为拓扑模型交换格式的可能性。比较了RDF与XSD两种表达方式的优缺点,分析得出XSD较之RDF更适用于IEC 61968的应用体系,但描述复杂拓扑模型时会产生数据冗余。通过添加外部引用、调整数据层次及减少双向关联等方式优化了XSD的结构,消除了冗余。给出了未来IEC 61968应用体系中二者的兼容方案与相互转换方法。研究成果在中国电科院研发的智能配电网信息互操作平台上得到了测试和验证。CIM-based static electrical network topology model is the data basis of power system advanced analysis applications. IEC 61970 uses Resource Description Framework （RDF） to express static topology model, while IEC 61968 follows but also puts forward the possibility of using XML Schema Definition （XSD） as the exchanging format of static topology model. The comparative analysis on the advantages and disadvantages of RDF and XSD syntaxes in- dicates that XSD is more adaptable to IEC 61968 architecture but may produce data redundancies when used to de- scribe complex topology model. By adding external reference, transforming data structure and reducing bidirectional associations, XSD structure is optimized and redundancies are eliminated. Finally a compatible way to use these two syntaxes in the future IEC 61968 application architecture is proposed along with a way for mutual transformation. The results have been tested and verified on the smart distribution grid information interoperation platform developed by China EPRI.
