Abstract

In this paper, an off-design performance prediction model for a single shaft industrial gas turbine (IGT) using Microsoft Excel with Visual Basic for Applications (VBA) programming is presented. The modelling architecture is comprised of fundamental thermodynamic equations describing the performance of IGTs. A graphical user interface has been constructed to allow an easy interaction of the model to predict IGT performance at different operating conditions. Component characteristic maps for the compressor and turbine with a bilinear interpolation method have been implemented in the Excel modelling architecture. A commercial thermodynamic toolbox (Thermolib, EUtech Scientific Engineering GmbH) which is compatible with Simulink environment has been considered to validate Excel model of the IGT system. This Excel modelling architecture could be a valuable reference tool for engineers and students to understand IGT performance at different ambient and operating conditions.

工业燃气轮机性能分析稳态热力学模型的开发

本文利用Microsoft Excel和Visual Basic for Applications (VBA)编程，建立了单轴工业燃气轮机(IGT)的非设计性能预测模型。建模体系结构由描述IGTs性能的基本热力学方程组成。构建了一个图形用户界面，使模型易于交互，以预测不同操作条件下的IGT性能。采用双线性插值方法在Excel建模体系结构中实现了压气机和透平的部件特征映射。考虑了与Simulink环境兼容的商用热力学工具箱(Thermolib, EUtech Scientific Engineering GmbH)来验证IGT系统的Excel模型。这个Excel建模架构可以成为工程师和学生了解不同环境和操作条件下IGT性能的有价值的参考工具。
