一种基于知识本体和SCL的数字变电站语义交换模型

摘要

IEC 61850采用面向对象建模技术对变电站业务功能进行建模,并通过变电站配置语言(Substation Configuration description Language,SCL)定义变电站配置描述对象模型.基于XML Schema的SCL无法实现对变电站自动化系统中所包含的知识语义进行有效的描述和传输交换.基于本体技术对变电站相关知识语义进行建模,分析变电站在知识语义方面的关联和约束关系,通过扩展SCL实现变电站知识的形式化描述能力,补充完善IEC 61850在知识语义描述方面的不足.%IEC 61850 adopts object-oriented modeling techniques to model business functions of the substation, and defines substation configuration description object model by Substation Configuration description Language (SCL). SCL which is based on XML Schema cannot description the knowledge semantic and achieve substation knowledge exchanging of substation automation system. Knowledge semantic of substation was analyzed and substation knowledge was modeled based on ontology technology in this article, including the relationships and constrains of substation knowledge semantic. By extending the label definition of SCL we build the semantic information model and improve the description ability of IEC 61850.
