摘要
在对小区燃气轮机冷热电联供系统稳态变工况模拟结果的基础上,经数据拟合,分别建立了以系统总火用效率和系统经济性为目标函数,以经冷却的压缩机进口空气温度、燃机发电负荷率、用于制冷的蒸汽量占总蒸汽量的比例三者为决策变量的系统运行的最优化模型。变工况模型的计算和最优化模型的求解提供了大量有用的结果数据和图线,可作为节能和经济运行的参考。对数据的分析得到了一些有意义的结论,可为我国小区冷热电联供事业提供参考。
On the basis of fire stable simulation of off- design conditions for BCHP systems the optimization models, of which the objective functions are the general exergefic effieiency and fire gross benefit of fire BCHPsystem respectively, am established in virtue of fitting the calculation data of the simulation, tire decision variables of the models being tire cooled air temperature at fire inlet of compressor, the power load factor of G-T, and the portion of steam for chillers. The simulation and the resolution of the optimization problems result in a great number of useful data and charts, which am to be the references to energy conservation and economical operation of the systems. By analyzing the data some significant conclusions are obtained, which will be helpful for fire BCHP industry.
