Research And Application Of Power Grid Fault Discrimination And Auxiliary Decision System Based On Multi-data Source Fusion

In recent years,the scale of power grids has developed rapidly,and various new technologies and equipment for power grid monitoring have emerged one after another,and power grid monitoring systems have also diversified.With the continuous implementation of the concept of "ubiquitous power internet of things,of the State Grid Corporation,it is increasingly difficult for dispatchers to make rapid decisions on the massive monitoring data of the power grid.How to break the barriers of power dispatching and monitoring systems,realize multi-source data extraction and convergence,and Providing accurate and fast grid-assisted decision-making information has become the key to the current regional power grid breakthrough.This paper aims to break the barriers of power system and promote the comprehensive application of grid data.It focuses on the current alarm information identification and fault diagnosis and recovery in the daily regulation and operation of Linyi Power Grid,and realizes the intelligent judgment and auxiliary decision-making recovery of power grid faults.The personnel provide a more convenient,comprehensive and comprehensive display of the grid operation status monitoring interiace,and assist the monitoring personnel to complete the fault proeessing quickly and accurately.The main research contents are as follows:(1)Extraction and fusion of multi-service system data in the control system.Including grid basic data mining,analysis and application,integrated modeling of primary and secondary equipment,multi-system data perception and extraction,and checking and identification of bad data.(2)The effectiveness of the alarm information of the control system is judged and confirmed.The construction and application of equipment fault inference rule base based on Petri net,the scope determination of power grid fault,power supply path search and power restoration scheme are proposed.(3)The application of fault identification and auxiliary decision-making system based on collaborative analysis of multi-source business systems,based on the demonstration and recovery process of main transfonner faults in Linyi Power Grid.
