The vibration phenomena which occur in rotary machines, such as power plants, can result in
catastrophic consequences. Any failure in any power plant section can result in extended
downtime and high repair expenses. Vibration is one of the most common causes of power plant
failure. The above-mentioned issues can be avoided using high-accuracy vibration detection and
prediction technologies. Therefore, further research into the primary causes of vibration on
Combined Cycle Power Plants (CCPPs) can help improve the present vibration evaluation
methodologies for power plants. This paper aims to survey some of the most commonly reported
factors that can induce vibration in the gas turbine of CCPP. Therefore, this paper aims at
reviewing the unbalancing and misalignment, contact among rotating and stationary components
(rubbing), steam flow fluctuations, the rotor critical speed, and shorted-turns, which are some of
the most common destructive vibrations in this industry. Furthermore, some of the most used
well-known technologies for vibration monitoring and evaluation in the gas turbine of CCPPs are
described, such as proximity probes, laser Doppler vibrometer, eddy current sensor, and accelerometer, which can be used to create a maintenance time schedule for the gas turbine of CCPPs
and also, it helps to reduce maintenance time and power generation costs.
