Modeling and simulation of single shafe heavy-duty gas turbine using SIMULINK

Zhongyi Li

Abstract

The object-oriented modularized technique basedon MATLAB/SIMULINK software is used to develop the module library of gas turbine components and to study the nonlinear dynamic simulation of gas turbine system.In order to improve the accuracy of the simulation,one nonlinear dynamic simulative model for single shaft heavy-duty gas turbine is proposed by using calculation method of variable specific heat,in which the actual composition,volume inertia and rotational inertia is taken into account.The research shows that the model is correct and rational with a clear and logical structure.The model can be used for the development and test of gas turbine controller,with good universality and expansibility.
