Abstract: In the context of integrated regulation and control, facing the massive demand for large-scale power grid regulation, regulatory personnel need to timely and accurately prioritize events, determine fault types and propose solutions. To address the work pressure caused by concurrent multi-events for control personnel, an ontology-based knowledge base for grid regulation has been constructed using ontology theory and methods, in conjunction with grid dispatching regulations. Additionally, an ontology-based reasoning and querying scheme for the grid regulation knowledge base is proposed. Compared to traditional electronic document querying schemes, this ontology-based knowledge base offers a concise and intelligent approach to information search and querying, facilitating tasks such as find information and check information.
