摘要

摘要: 采用VC和MATLAB混合编程方法,进行了不同循环燃气轮机的变工况性能分析.其中,采用修正工程算法编制了工质热力性质计算程序,采用反向传播(BP)神经网络法建立了压气机和涡轮部件特性计算模型,采用模块化建模方法建立了简单循环、蒸汽回注(STIG)循环和化学回热(CRGT)循环性能仿真模型.仿真结果表明:在保持燃机几何结构和设计功率不变的条件下,STIG循环和CRGT循环均能降低燃气初温和提高循环热效率.其中,简单循环的热效率为35.16%,STIG循环的热效率可达到45%,CRGT循环的热效率可达到52.8%;为了进一步提高该型燃机的应用潜力和使用范围,可以将该型CRGT循环燃气轮机用于海水淡化应用中.

Abstract: Design and off-design performance of the different cycle in one certain three -spool gas turbine,with the combination programming method of VC and MATLAB was analyzed.Among it,used the modification engineering algorithm method to program the computation procedure of the working medium's thermodynamic properties,used the BP (back propagation) neural network method to build the calculation models of the compressor and turbine component characteristics;used the modular modeling method to build the dynamic simulation models of the simple cycle,the STIG(steam injection gas turbine) cycle and the CRGT(chemically recuperated gas turbine) cycle.The calculation results show that the STIG cycle and CRGT cycle can both reduce the combustor exit temperature and improve total thermal efficiency,in which the simple cycle's efficiency was 35.16%,the STIG cycle was 45% and the CRGT cycle was 52.8%;and in order to ensure the efficiency and the application areas,this CRGT cycle units can be used in the seawater desalination systems,under the safe operation areas and without the redesign of the components.
