Gas turbine plant of simple cycle with development of vibration monitoring systems

Abstract

Aim: to develop an efficient and accurate vibration monitoring system and chose and mount vibration sensors for the designed GTP to ensure accurate reading of vibration values Gas turbine plants operation parameters are affected by the design of the GTP and the ambient conditions temperature and pressure, a thermodynamic calculation were done on the designed GTP to calculate the change in temperature and pressure through different sections of the designed GTP. Based on the thermodynamic calculations a gasdynamic calculation were done to determine the optimal diametrical sizes on each section of GTP, and to calculate the compression work distribution between LPC and HPC and to determine the number on stages for each of LPC, HPC, LPT, HPT and PT. A strength calculation were done on GTP elements to determine the tension stresses from the centrifugal forces and the bending stress from gaseous and centrifugal forces the first strength calculations were done on turbine rotor blade on four cross sections on root 25%, 50% and 75% of the blade length, the second strength calculations were done on the turbine disc. As any rotary machine faults in any of the GTP elements can happen but with a good system for monitoring the health of the GTP parts the faults can be either predicted or prevented before happening this system is Vibration Monitoring system this part is focused on better understanding of vibration Monitoring and the development of the system itself. Vibration sensors were chosen taking into account the vibration limits of the GTP elements and the purpose of the sensor with working limits of the sensor itself.
