Abstract
The optimal performance of maintenance actions contributes to the economically
competitive operation of gas turbines. For the optimisation, the condition of the
gas turbine components and the cost effects of possible degradation must be
known. This paper presents the necessary measured data and the condition
parameters to evaluate the thermodynamic condition of a gas turbine in relation
to the selected faults. The special requirements and application principles for a
steady-state gas turbine model to be used for cost flow estimation are also
addressed. The resulting information from condition monitoring is applied to a
model-based optimisation of gas-turbine maintenance with the focus on two
example cases: 1) the timing for compressor on-line and off-line (crank)
washing, and 2) the timing for the inl
