abstract

Health Monitoring Systems (HMS) based on operating state determination techniques that make use of field measurements are subjected to inaccuracies arising from measurements unreliability due to various kinds of uncertainties (such as sensors faults, measurements inaccuracies, etc.).

In this paper, some techniques to improve the accuracy of gas turbine health state determination are presented:

- a measurement conditioning technique based on the expected and trend values of measurements;

- the evaluation of the best measurements/health parameters combination that should be used with respect to the gas turbine operating state determination.
