摘　　要：为了提高基建期间汽轮机运行的经济性,根据这一阶段的运行特点,分析了主蒸汽压力变化对功率的影响,建立了机组最优主蒸汽压力计算模型。对国产300MW汽轮机组计算的结果表明该模型简单适用,满足工程的实际需要,能够为机组高效率运行提供依据。In order to construction, based on conducted to investigate mathematical model of o improve the heat economic performance of steam turbine during capital operating characteristic in this time, a comprehensive analysis has been the influence of main steam pressure on the steam turbine power output, and ptimal main steam pressure has been built. Through the calculation for the home-made 300MW units, it is demonstrated that the model with applicability satisfy the actual requirement of project.
