Abstract

A gas turbine performance prediction tool has been implemented using a simulation software package to accurately predict the performance of SGT5-4000F heavy-duty gas turbines. Comparing the results obtained from this simulation with data collected from the field, a significant agreement between them is found within an acceptable tolerance of about 4%. The model has been built to work at both steady state and transient combining the control protocols, thus achieving the maximum allowable output power with various operating parameters. This study aims to use the implemented model to investigate the effect of Steam Injection Gas Turbine cycle (STIG) as well as the change in ambient temperature on the performance of the unit in terms of both output power and efficiency. The results indicate a significant improvement in performance using this specific technology.
