Abstract

This research endeavors to utilize gas path analysis and vibration monitoring techniques to develop a proactive model for analyzing gas turbine (GT) characteristics based on shaft speed. The study begins by formulating the governing equations of the rotor shaft system to accurately capture its dynamics. Specifically, the modeling of shaft speed dynamics is conducted to understand its impact on GT performance. Various sensors are employed for detecting faults in gas path parameters, crucial for maintaining turbine health. The results are presented which shows the 4976rpm is highest value of shaft speed and the lowest value is 452rpm. faults are likely to occur at very high speed and this is shown in this research as fault probability is increasing with an increase in shaft speed. Surface plots illustrating the effects of shaft speed in conjunction with pressure and temperature on identified faults are shown in this research. This research aims to provide valuable insights into optimizing GT operations and mitigating potential issues, ultimately enhancing turbine reliability and efficiency.
