Abstract :
This paper presents an application of the Ca~En model-based diagnosis software to a GE Frame 6 gas turbine. The paper focuses on the fault detection task and presents a mixed strategy, which combines an observer strategy with a simulation strategy, to achieve a good robustness/sensitivity trade-off. The presented application results have been obtained by running Ca~En in real-time on the GE Frame 6 turbine owned by National Power at Aylesford (UK).
