Abstract： Aiming at researching the dynamic characteristic of a small gas turbine in different kinds of environment，and on the basis of the laws of the conservation of mass and energy，a blocking modeling method was employed to reasonably carve up the small gas turbine. The math models of compressor，combustion chamber and turbine were built. Modelica and Dymola with multi-domain language，which is an object-oriented，were used to program and build relative simulation models. Taking a lab-scale of gas turbine as an example，simulating results were compared with actual plant's performance. The research results indicate that the errors of the built models of the lab-scale of gas turbine are small enough for further general and expansible application.
