Gas Turbine Power Plant System: A Case Sudy of Rukhia Gas Thermal Power Plant

The reliability of the GTPPS were analyzed based on a five and half -year failure database. Such reliability has been estimated by selecting Proper model and different models for repairable system analysis were discussed. The reliability estimation by using Nonhomogenious process and Homogenous renewal Process are explained. Non Homogeneous Process was further divided into Power law Process and Log Linear model. The analysis showed that combustion chamber compressor and Generator of gas turbine unit follow Power law process and Turbine unit follow log linear model and Electrical system follow the Renewal Process.. Reliability Pattern at different Operating interval was drawn and the behavior was analyzed. The behavior shows abnormality in some component level. Finally Reliability Patern at system level was analyzed by the reliability pattern at different operating interval. From the Pattern of the Graph it can be concluded that Parallel system reliability with two unit standby is better than the Reliability with one unit standby. .All the units showed consistent reliability improvement in different operating intervals. Few components and the whole system showed abnormal trend in Reliability. This has to be further investigated The management of Power Plant has option either to keep one unit as stand by or two units as stand by or running all the units Parallaly. The component Performances are also determined by this way and one can have option how to run the plant in most
