Design of Section Limit Question Answering System Based on Knowledge Graph

The stable operation limit of power grid is an important boundary condition for the safe and reliable operation of power grid. When the operation mode of power grid changes, if the dispatcher can timely obtain the section limit, it will reduce the fault handling judgment time and improve the power grid control capacity. This paper proposes the design of section limit question answering system based on knowledge graph, which can parse the natural language questions, query the power grid operation rules knowledge graph to obtain section limit, and improve the efficiency of the dispatcher's control measures.
