Abstract

The operation and maintenance of substation equipment is of great significance to ensure the safety and stability of the power grid. In order to summarize the historical operation and maintenance experience of substation equipment and facilitate the management personnel to uniformly manage and accurately query the historical data of substation faults, this paper constructs an intelligent question and answer system for substation faults based on the knowledge map. At present, the research on knowledge atlas in power field mainly focuses on the construction and visualization of knowledge atlas. This paper combines natural language processing, deep learning, knowledge atlas, graph database and other knowledge with power. Firstly, the substation fault data is cleaned and extracted, and the substation fault knowledge map is constructed; Secondly, based on Bert+TextCNN algorithm, the intention recognition function of questions is realized; Thirdly, based on BILSTM-CRF algorithm, the named entity recognition function of questions is realized. Finally, combined with Flask deployment model, the API interface is released, and the substation fault question answering system is built through the establishment of WeChat automatic question answering robot. The experimental results show that the accuracy of the system reaches 96%. Finally, a complete question answering system for substation fault is formed, and accurate, fast and intelligent knowledge question answering service is realized.
