NRI Annual Research Report 2001-2002Project Title:On-line Fault Diagnosis in Synchronous GeneratorSummary:Department: ElectricProject Manager: H. MirabediniMachinesContractor: Niroo ResearchProject Code: PEMVA01InstituteProject Staff: A. Tajian, D. Jalali, E. Khosroshahli, S. Soleymani, Sh.Shakibaee,M. Zarghami, M. Asgari, A. Ghalegolabi, F. Keshmiri, A. Gorji,Gh. Manibi, F. HonarvarIn this project, data collection, analysis and sorting of large synchronous generatorfaults in Iran Power Plant (from 1985 to 1995) and different methods of electrical andmechanical fault diagnosis were done side by side.The different methods of fault diagnosis by partial discharge analysis (PDA) wasstudied completely. At last the on-line partial discharge analyzer was installed on oneunit of Neka Power Plant in order to survey it’s ability to diagnose insulation problems.16
NRI Annual Research Report 2001-2002(1) Coupling Capacitor by High-voltage Cable to Bus GeneratorProject Results:(2) Termination BoxData files of fault occurrence in generator power plant were made known;Partial discharge analysis and vibration analysis can detect the most probable faultsin power plant generator.On-line fault diagnosis can predict faults in their first stays and stop theirspeed and loss of money.−−−−−Project Documentation:Electric Machines Department; Report of “Matlab PDE Tools Ability forField Analysis”; Electric Power Systems Research Center; NRI.Electric Machines Department; Report of “Touss Power Plant Alarm andExcitation Analysis”; Electric Power Systems Research Center; NRI.Electric Machines Department; Report of “Stator Winding Fault Diagnosis byANN”; Electric Power Systems Research Center; NRI.Electric Machines Department; Report of “The Survey of InsulationProblems in Rotating Machines”; Electric Power Systems Research Center; NRI.Electric Machines Department; Report of “The Survey of On-line and OfflineFault Diagnosis Methods”; Electric Power Systems Research Center; NRI.17
