doi:10.11930/j.issn.1004-9649.202401026

Abstract

Abstract:

In order to improve the response capacity of power grid fault disposal, an adaptive understanding framework of fault disposal information is proposed. The framework is based on the constructed multi-task collaborative understanding model and the fault disposal knowledge graph to identify the power grid fault alarm, operation status, operation instruction and other information, and the fault disposal operation strategy is generated by reasoning adaptively. By establishing the evaluation index system and test data set of fault disposal information, the experimental effect of the adaptive understanding framework of fault disposal information and multi-task collaborative understanding model are verified.

Key words: fault disposal, multi-task collaborative, knowledge graph, adaptive reasoning
