Faults detection in gas turbine rotor using vibration analysis under varying conditions

Benrabeh Djaidir, Ahmed Hafaifa, Abdallah Kouzou
Monitoring of rotating machines is a very important task in most industrial sectors, which
requires a chosen number of performance indicators during the exploitation of such kind
of equipments. Indeed, for understanding the undesirable phenomena complexity of the
industrial systems under operation, a reliable and an accurate mathematical modeling is
required to ensure the diagnosis and the control of these phenomena. This work proposes
development of a fault monitoring system of a gas turbine type GE MS 3002 based on
vibration analysis technique using spectral analysis tools. The obtained results prove the
effectiveness of the presented monitoring tool approach which is applied on the gas turbine,
for avoiding the operation under vibration mode and for generating optimal performance
during the exploitation of the gas turbine.
