Abstract

In this paper, a model of a three-shaft gas turbine which is based on modular modeling method has been founded by MATLAB/Simulink to study its performance. By combining the least-square and neural-network method in the process of modeling, we fit the gas turbine characteristics, and get a more accurate characteristic curve. Finally, according to experimental data in some working conditions, we calculate the simulation model in order to obtain the steady-state value of import and export of its components and the curve in variable working conditions. After comparing the experimental data with the simulation data, it´s proved that the simulation results are highly accurate.
