Ontology-Based Semantic Description for Substation Devices

At present, the development of smart grid has already formed a consensus in the world. As an energy depletion big country, the development of smart grid has very important significance in China. Transformer substation plays a very important role in the smart grid, so do semantic description of substation equipment and improve their interoperability can effectively raise the intelligence application of the transformer substation. The ontology technology based on semantic sharing has unique advantages in describing the concept and relationship. Therefore, to build up ontology for substation equipment and to describe it using the ontology description language-OWL can achieve power equipment information sharing, interaction and processing, which provides a new method to build smart grid.
