中文摘要：

为了对电力行业复杂的故障信息进行有效的知识管理，本文将本体论方法引入到设备故障信息的知识表示中。利用OWL本体语言的知识表示特性，介绍了基于OWL的电厂设备故障特征知识表示的过程，为特定领域知识的公共一致表示提供了新的思路，本研究结果不仅可以促进电力行业知识的共享和重用，还方便了电力行业内部以及企业间知识管理和信息交换。

英文摘要：

In order to carry out the effective knowledge management for the complex fault information of electric power trade, in this paper, an ontology methodology is proposed to take knowledge representation of equipment fault information. The process of knowledge representation for fault characteristic of equipment in power plant is described with the use of the trait of knowledge representation, provides new way for uniform representation of knowledge in specific domains. The result of this research not only can promote the share and reuse of knowledge in power plant, but also makes a convenient for knowledge management and information exchange in electricity industry and among the enterprises.
