Abstract:In order to achieve quick design, performance optimization and analysis of combined cycle unit, the platform interface for thermal performance calculation of gas and steam combined cycle was developed using object-oriented and mixed programming technology based on the laws of thermodynamics. For the process structure of gas and steam combined cycle system, the combined cycle thermal performance calculation module was compiled using Fortran language and was linked to C# interface programs by mixed programming technology, then the compile of software interface was completed. The overall architecture of interfaces as well as realization and inheritance of classes were proposed, and form classes, computing interface classes and sensitivity analysis interface classes were constructed, then the function of performance calculation was achieved. The software can quickly carry out cycle scheme design, optimization and performance analysis under design and/or off-design condition, etc., and provide meaningful guidance for design and optimization of the unit.
