Method and device for constructing power grid dispatching fault processing knowledge graph

Abstract

The invention discloses a method and a device for constructing a power grid fault processing knowledge graph. Domain high-quality professional phrase mining and named entity identification are carriedout; relationship extraction of equipment, events, operations and the like is carried out; knowledge is automatically extracted from massive structured and unstructured data such as power grid operation data and fault processing plans; a power grid dispatching fault processing knowledge graph is constructed, the limitation that a traditional power grid dispatching expert system customizes knowledge regularly and is long in period and slow in updating is well broken through, and computer intelligent autonomous collection, cross-domain analysis and all-time learning of the power grid dispatching fault processing knowledge are achieved.

Description

technical field [0001] The invention relates to a method and a device for constructing a power grid scheduling fault processing knowledge graph, and belongs to the technical field of power grid fault processing. Background technique [0002] When the dispatcher on duty of the power grid handles faults, he needs to follow the dispatching regulations and the safe and stable operation regulations, summarize the information of the sub-system power grid operation, power grid failure, equipment maintenance, meteorological environment, dispatching logs, risk assessment, etc., and combine the failure plan, operation mode arrangement, load Predetermined policies such as quick transfer plan to form a fault handling plan. Among them, information such as dispatching regulations, safe and stable operation regulations, failure plans, operation mode arrangements and adjustments, and fast load transfer plans usually exist in text form, and information such as power grid operation, power gri...
