The Research Of Fault Diagnosis Method For Power Grid Based On Double Data Source

This paper analyzes the quesitions of the fault diagnosis system for the regional power grid,which were discoved in practical run,bring up improving measure,and put forward measures for improvement,implement the fault diagnosis procedures and scheduling data platform separation functions.These measures improve the debugging efficiency without affecting the online operation of real-time basis,and facilitate the analysis the correctness of fault diagnosis system conclusions.The improved fault diagnosis system was used in Dingxi decision support system for power grid dispatching.This paper designs a fault diagnosis system to solve the existing shortcomings of fault diagnosis system,which can utilize the double data source of SCADA system and fault information system.The new system changes the past practice of passive acceptance of data,and queries the history library for necessary data activily in accordance with the diagnosis demand.The new system also be able to deal with multiple diagnosis flow simultaneously,and will not miss other fault since the fault diagnosis occupy a large amount of time.
