燃气轮机呈现出多学科交叉特性及多系统耦合特征，使得单一学科的仿真模型难以满足其综合性能分析需求，亟需开展燃气轮机多系统耦合仿真研究。为开展燃气轮机的多系统耦合仿真研究，本文将基于FMI接口的多系统集成方法应用于燃气轮机的多系统耦合建模，提出基于MWorks的燃气轮机多系统耦合仿真模型构建方法。首先，利用针对不同物理领域的专用软件工具开发子系统仿真模型；其次，基于标准化接口协议建立不同系统间的标准化数据通讯接口并导出为统一文件格式，基于统一平台构建多系统耦合燃气轮机总体性能仿真模型；最后，通过阶跃响应仿真验证模型的动态特性，仿真结果说明基于该方法的多系统集成模型间数据互通稳定，能够满足燃气轮机多系统、多领域耦合模型的建模需要。
Gas turbines exhibit interdisciplinary characteristics and multi-system coupling features, making it difficult for a single discipline's simulation model to meet the comprehensive performance analysis requirements. There is an urgent need to carry out multi-system coupling simulation research for gas turbines. To conduct such research, this paper applies a multi-system integration method based on the FMI interface to the multi-system coupling modelling of gas turbines, proposed a construction method for a gas turbine multi-system coupling simulation model based on MWorks. Firstly, subsystems simulation models are developed using dedicated software tools for different physical domains. Secondly, a standardized data communication interface is established between different systems based on normalized interface protocols and exported to a unified file format, constructing an overall performance simulation model of the multi-system coupled gas turbine on a unified platform. Finally, the dynamic characteristics of the model are validated through step response simulation, with simulation results indicating that the data interchange between the multi-system integrated models based on this method is stable, meeting the modelling needs of gas turbine multi-system and multi-domain coupling models.
