In this study, an in-house program to predict steady state operation of micro gas turbines is constructed using Matlab Simulink. The program consists of two parts: design and off-design simulations. The program is fully modular in its structure. Performance of each component (compressor, combustor, turbine, recuperative heat exchanger and pipe elements) is calculated in a separate calculation module using mass and energy balances as well as models for off-design characteristics. The off-design modules of compressor and turbine use performance maps, which are program inputs. The off-design operation of a micro gas turbine which is being developed is predicted by the program. The prediction results are compared with those by commercial software, and the validity of the program is confirmed.
