In order to further improve the accuracy of nonlinear simulation models, the purpose of this paper is to make some improvements to the general mode.
This paper adopts the calculation method of variable specific heat, taking the variation of gas‐oil ratios and discharge pressure into account, and establishes a nonlinear dynamic simulative model of biaxial gas turbine considering about the inertia of volume based on MATLAB/SIMULINK.
The simulation result, compared with test data, shows that this simulative model is more accurate to reflect the system's dynamic characteristics.
The hot inertial has not been taken into account. Meanwhile, the quantity of data is less, so this paper adopts interpolation method.
It is used to simulate calculation of gas turbines.
This paper adopts the calculation method of variable specific heat, considering the effect of the gas‐oil ratio variation and the discharge pressure variation (the total pressure of discharge duct) on the system.
