Abstract
The industrial gas turbines which are in service for power generation and mechanical drive are operated in different environmental conditions. The changes in environmental conditions could affect the performance of different main subsystems and also overall performance of the engine. It is very crucial to have a good insight regarding the behavior of the engine under different inlet air conditions. This paper presents the SGT-600 twin-shaft gas turbine design and off-design model for mechanical drive applications. Also the integration of components and component matching of the gas turbine at base and part loads are studied. The characteristic curves of each component derived from three-dimensional numerical simulations, were validated with experimental data in a separate study. The results of simulation are presented at the part load and different ambient conditions are validated with test measurement data. The results show good agreement between the experimental data and analytic model.
