Monitoring and Diagnosis Methods for High Voltage Power Transformers

چکیده
Transformatoarele de putere de înaltă tensiune reprezintă unele din cele mai costisitoare echipamente din staţiile electrice din sistemul electroenergetic. Defectele şi opririle accidentale ale acestora nu cauzează numai costuri cu reparaţiile; ele conduc şi la pierderi ecomonice datorate întreruperii alimentării consumatorilor. Testele preventive şi monitorizarea on-line sunt benefice pentru prezicerea condiţiilor incipiente ale defectelor şi pentru stabilirea/programarea acţiunilor de mentenanţă şi de retrageri din exploatare/înlocuire. De aceea, în lucrare, s-a realizat o sinteză a posibilităţilor de monitorizare on-line şi a sistemelor de detecţie şi diagnoză a defectelor pentru menţinerea parametrilor optimi de funcţionare şi a unei disponibilităţi mărite pentru transformatoarele de putere existente.

متن کاملPower transformers health index calculation using reliability methods for the case study of the Dez Dam and Karkheh Dam hydro power plants
Transformers in power plants act as intermediaries between the power plant and the power grid, which are affected by electrical stresses such as switching, thermal stresses such as overload and arc, and chemical reactions in the dielectric oil. Acid and moisture components cause deterioration of transformer oil and paper insulation. Condition assessment of transformers is a method to predict an...
متن کاملModeling the Frequency Response Movements in Power Transformers for Predicting Purposes
Power transformers are key components in electrical power supplies and their failure could cause severe consequences on continuity of service and also generates substantial costs. Identifying problems at an early stage, before catastrophic failure occurs, is a great benefit for reliable operation of power transformers. Frequency Response Analysis (FRA) is a new, well-known and powerful diagnost...

متن کاملA Bidirectional DC-DC Convreter with Zero Voltage Switching Capability for Energy Storage Application
In this paper, a bidirectional DC-DC converter with high power density for energy storage application is proposed. The presented converter provides power transfer in both directions only with adjusting phase shift angle. Zero voltage switching (ZVS) in both turn on and turn off moments of all switches is the major capability of the converter that makes it suitable for high power applications. Z...
متن کاملInsulation Fault Diagnosis in High Voltage Power Transformers by Means of Leakage Flux Analysis
Power transformers in service are subjected to a wide variety of electrical, mechanical and thermal stresses capable of producing insulation faults. This type of failure figures amongst the most costly faults in distribution networks since it produces both machine outage and electrical supply interruption. Major research effort has therefore focused on the early detection of faults in the insul...
