摘要
利用Thermoflex软件模拟了具有不同燃气初温和压比的燃气轮机,并用模拟的燃气轮机设计联合循环电站。采用燃气轮机维护费用因子对选用不同燃气轮机电站的经济性进行计算,并对天然气价格提高的情况也进行了讨论。目的是分析燃气轮机燃气初温提高引起的成本和维护费用增加对电站经济性的影响。分析结果表明:采用更高初温的燃气轮机的联合循环电站并不一定具有更高的经济性。所得结果可作为联合循环电站燃气轮机选型的参考。
Thermoflex software is used for simulating gas turbines with different pressure ratios and turbine inlet temperatures and also for simulating gas turbine combined cycle power plants. Gas turbine maintenance cost coefficients have been used for calculating the profitability of power plants equipped with different gas turbines. The case of rising prices of natural gas is being discussed. The influence of cost and maintenance expenditure＇s increase, for cases of gas turbines with higher inlet temperature, on the power plant＇ s profitability is being analyzed. Results indicate that a combined cycle power plant＇s profitability doesn＇t unconditionally increases with using gas turbines of higher inlet temperature. These results may serve as a reference for type option of gas turbines concerned. Figs 9, tables 3 and refs 4.
