Power grid accident information automatic filling and auxiliary decision-making method based on event graph

Abstract

The invention relates to a power grid accident information automatic filling and auxiliary decision-making method based on an event graph. The method comprises the following steps: firstly, performing natural language analysis on a text of a power grid accident record, performing information extraction, obtaining a relationship between accidents and a processing condition of the same type of accidents, combining an OMS, realizing automatic classification and input of accident information according to classification labels such as an accident occurrence area range and an accident type, then constructing an ontology by using an OWL language, inputting the extracted information, constructing an event ontology, communicating the events by taking the transition probability between the events as a connection, and establishing an event graph model. According to the invention, based on the theory and method of the event graph, on the basis of a power grid accident record text, rapid, accurate and comprehensive power grid fault information extraction and automatic filling are realized through a natural language analysis technology, an instantiated power grid accident record event graph is constructed, and various functions of information search, auxiliary decision making, accident analysis and the like can be provided for operators.

Description

Technical field [0001] The present invention relates to a method of establishing a grid pattern affair automatic accident reporting and decision support information based on information relating to particular binding system OMS automatic accident reporting affair map. Background technique [0002] Energy and electricity has become the main driving force of modern industrial production. Due to the power grid itself characteristics, launch failure is inevitable, fault history is of great significance for the future to deal with failure, the current use of OMS system to achieve accident information sharing and orderly integration. However, in the case of an accident-prone, dispatchers must not only deal with the power grid accident, but also on the different accident records and log in manually fill in the OMS system. However, the need to manually edit an incident recorded at least five minutes, and if more accidents occur simultaneously, leading to the dispatcher could not complete...

AI Technical Summary

Problems solved by technology

However, it takes at least 5 minutes to manually edit an accident record. If there are many accidents and occur at the same time, the dispatcher cannot complete the job in time, which will affect the processing speed of the accident.

In addition, due to the inability to establish the connection between accidents and the different handling methods for the same type of accident under different conditions, these lead to the inability to form an effective system for the reported information, and it is difficult to play an auxiliary decision-making and analysis role in future accident handling , causing the value of historical information to be greatly wasted
