公共语义模型是解决IEC 61970和IEC 61850标准无缝衔接的核心,但在具体建模应用实践中,还需要进一步解决如何提高模型及模型映射的表达能力和自动维护能力,以及增强其在业务建模方面的拓展能力2个方面的问题。文中引入本体定义元模型(ODM),按照模型驱动架构(MDA)的思想,在美国电力科学研究院(EPRI)的公共语义模型的基础上,建立了从构建可视化建模环境到最终的领域业务建模的一个完整的电力系统建模框架。并重点就其中的元模型可视化构造、网络本体语言(OWL)业务建模方法、映射引擎设计以及约束及推理机制等关键技术结合具体实例进行了深入研究。实践表明,该框架一方面可以提高公共语义模型清晰、灵活的表达能力,另一方面实现了从静态建模到具体领域业务建模的拓展。
The public semantic model is the core to solve the seamless connection between IEC 61970 and IEC 61850 standards. However, in the practice of concrete modeling, it is necessary to further solve the problem of how to improve the expressive ability and automatic maintenance ability of model and model mapping, Mold aspects of the ability to expand two aspects of the problem. In this paper, Ontology Definition Metamodel (ODM) is introduced. Based on the idea of Model Driven Architecture (MDA) and on the basis of the public semantic model of the American Academy of Electric Power Research (EPRI), the paper builds the framework from constructing visual modeling environment to final domain business Modeling a complete power system modeling framework. The key technologies such as meta-model visualization construction, OWL business modeling method, mapping engine design, and constraint and reasoning mechanism are also discussed emphatically. Practice shows that this framework not only enhances the clear and flexible public semantic model, but also expands the business modeling from static modeling to specific areas on the one hand.
