Abstract

In this study, an analysis of the performance of a twin-shaft industrial gas turbine (IGT) during hot-end damage in the gas generator turbine (GGT) at high-power operation has been carried out using a validated Simulink IGT model. The Simulink model is based on fundamental thermodynamics and allows the implementation of correlation coefficients in the GGT module to predict the performance of the IGT system during a hot-end GGT damage incident. Measured field data from a twin-shaft IGT operated as a power generation unit denoting a reduction in performance due to hot-end GGT damage are considered for the analysis. Four hot-end GGT damage incidents across a range of measured field data have been identified and considered for the analysis. The results show that the Simulink model can predict the change of physical parameters (pressure, temperature) across the IGT system for each GGT damage incident. Hot-end damage increases the flow capacity and reduces the efficiency of the GGT. Future work will validate the dynamic change of flow capacity and efficiency during different GGT damage incidents.
