Practically Research On Fault Diagnosis System For Local Grid

With analying our country's local grid practical function and summarizing outcomes of current fault diagnose research ,this text has researched the main factors which influence the appliance of fault diagnose in practice and desiged a suitable fault diagnose for our country's grid current situation. System adopt method of expert system , Object-Oriented knowledge representation is adopted to represent all kinds of fault information and related relations of different equipment in the grid while production rules to represent the diagnostic rulesan and grid structure.After the grid fault occur,this system will collect SCADA information and data on fault information system, through different inference on various type of fault information about fault equipment, evaluate motion switch and protector behaviour and draw a malfunction report.
