Semantic Modeling Method of Highly Elastic Power Grid Based on OWL

Abstract

As an important supporting technology for the development of power grid, highly elastic power grid is the intelligent development of power grid, which can effectively improve the information level of power system. However, due to the massive terminal data, various communication modes and independent application platforms, it is very difficult to extract a unified and effective data expression format from complex equipment, which hinders the power system to achieve intelligent services. In this paper, the ontology description language OWL is used for semantic extension, and the understanding gap between heterogeneous identifiers is eliminated by adding device semantics. Through the establishment of equipment information, service overview and quality of service ontology model, the interconnection between heterogeneous identities of highly elastic power grid terminals can be realized, which can conveniently carry out intelligent control of transmission/transformer/distribution equipment.
