Dynamic simulation of gas turbine is useful in a variety of design analysis and test
applications. Mathematical models employing estimated or experimentally derived
component characteristic have been widely used, especially for near design point studies
of acceleration and deceleration transient and control strategies.
Most of the dynamics simulations results emphasis on the behavior of healthy engine at
different condition. In this paper a different approach has been considered. In addition to
investigating the dynamic simulation and behavior of healthy engine, the effect of aging
on the performance and behavior of the engine is evaluated using a new fault model for
the whole engine. These results show that two parameters affect torque requirement of
sample gas turbine (in this case Siemens V94.2): fuel flow and speed. If fuel flow is kept
at its maximum available value, aging causes reduction in gas turbine speed at a fixed
demanded torque.
Therefore it could be concluded that two reasons cause reduction in power and torque
with considering aging effect. First to keep exhaust temperature constant (try not to
increase in TIT) and second to keep speed constant (for a single shaft gas turbine).
