基于Modelica语言的燃气涡轮建模及应用

为了对燃气涡轮的性能进行更好的仿真研究，利用模块化建模的方法，并根据质量和能量守恒的原理，把燃气涡轮分为流动模块和容积模块两部分。其中．容积模块看作是质量和能量的集聚，流动模块看作是质量和能量的流动。采用新型的、面向对象的仿真软件Modelica编制了燃气涡轮的仿真模型，建立了可扩展的燃气涡轮程序库，并利用该程序库与其它模型库结合，搭建了单轴燃气涡轮发动机模型，得到了合理的仿真结果，验证了该方法可行及推广应用价值。图11参8

Gas Turbine Modeling and Its Application Basing on the Modelica

In order to simulate the performance of gas turbine, according to modular modeling means and mass and energy conservation, the gas turbine is divided into two parts: the flow model and the volume model. The flow model is the result of a modeling abstraction, where the volume is neglected. The volume model mainly indicates duct connecting. It can be thought that storages of the mass and the energy are modeled in the control volume, whereas the flows of the mass and the energy are modeled in the flow model. In order to get simulation models, the Modelica is introduced to program models and the Modelica is an object-oriented and non-casual language for modeling of the lager, multi-domain system. In the paper, the gas turbine models are programmed and the extensible gas turbine libraries are constructed by the Modelica. On the basis of gas turbine models and other models, the single spool gas turbine is simulated. The rational simulating results are obtained and the method is verified to be reasonable.
