摘　　要：为了研究小型燃气轮机在不同环境下的动态特性,采用模块化建模方法,并根据质量和能量守恒原理,对小型燃气轮机进行了合理划分,建立了压气机、燃烧室、透平等单元部件的数学模型,并将这些部件划分为容积模块和流动模块。采用面向对象的、多领域的物理系统建模语言Modelica和Dymola编译器编制了各部件的仿真程序,建立了SmallGasTurbine通用模型库,以方便不同结构系统的小型燃气轮机的模型搭建。以川崎M1A-13D、M7A-01小型燃气轮机为例,搭建了它们的系统模型,将厂家给定基本数据与仿真结果进行了对比。研究结果表明,小型燃气轮机模型模拟仿真误差较小,具有很高的精确度。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.
