  • 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.
