摘要(Abstract):
配电网统一信息模型是实现智能配电网信息交互和应用集成的基础,但模型版本更迭和私有扩展造成的信息模型异构会导致语义冲突,导致互操作的失败。为解决这些问题,文章实现了基于本体映射分析的公共信息模型在不同版本间的转换映射方法。首先提出了基于本体的信息模型转换映射算法,通过SAX解析确定CIM/RDF中待转换的元素,设计深度搜索算法得出待转换类和属性的映射规则库。在此基础上,使用扩展样式表转换语言(XSL transformation,XSLT)技术实现了CIM/RDF等实例数据向不同版本模型定义的数据格式的映射,完成了异构域XML的自动转换,并以变化较大的变压器模型作为算例说明转换过程和方法。文中成果为异构模型交互提供了模型映射基础,有助于信息交换总线上实现异构模型的辨识与交互。
