【Abstract】 Nonlinear mathematical models for a steam-injected gas turbine are driv-ed in this paper. In the formulating process of models, variable specific heat, intermediate plenum efficiency and heat transfer in gas path are considered to make the mathematical models more accurate. With the computer programs on the basis of these models, static and dynamic characteristics of the gas turbine are analyzed in detail. Some valuable conclusions have been obtained.更多还原
