| description | Accurate and simple prediction system has become an urgent need in most
disciplines. Having the accurate prediction system for gas turbine components will
allow the user to produce reliable creep life prediction. Focusing on the turbine
blades and its life, the current method to calculate its creep life is complex and
consumes a lot of time. For this reason, the aim of this research is to use an
alternative performance–based creep life estimation that is able to provide a quick
solution and obtain accurate creep life prediction. By the use of an artificial neural
network to predict creep life, a neural network architecture called Sensor Life Based
(SLB) architecture that produces a direct mapping from gas path sensor to predict the
blade creep life was created by using the gas turbine simulation performance
software. The performance of gas turbine and the effects of multiple operations on
the blade are studied. The result of the study is used to establish the input and output
to train the Sensor Life Based network. The result shows that the Sensor Life-Based
architecture is able to produce accurate creep life predictions yet performing rapid
calculations. The result also shows that the accuracy of prediction depends on the
way, how the gas path sensor is grouped together. |
