摘　　要：考虑实际气体的热力性质,建立了三轴燃气轮机中冷循环的热力模型,以循环功率和效率为优化目标,对中间压比(或低压压气机压比)的分配进行了优化,同时分析了低压压气机进口气流温度、中冷度和总压比对循环性能的影响。研究发现,与不考虑实际气体热力性质的研究结论相比,循环功率或效率最大时的中间压比并不等于高压压气机压比。The thermodynamic model of a triple-shaft intercooled gas turbine cycle was established with the real air characteristics taking into account. The performance was optimized by taking the power output and the efficiency as the objectives by searching the optimum intercooling pressure ratio, and the effects of the low-pressure compressor inlet temperature, the effectiveness of the intercooler and the overall pressure ratio. The study shows the optimum intercooling pressure ratio at the maximum power or the maximum efficiency is not equal to pressure ratio of the high-pressure compressor with the real air characteristics taking into account.
