摘　　要：为了改善汽轮机的运行经济性,建立耗差分析模型,可以将当前运行工况与基准运行工况间汽轮机热耗的偏差分解至各监控参数相应的偏差,从而为运行调整提供指导。采用等效焓降分析方法,建立了循环参数偏差的耗差模型,不仅统一了汽轮机耗差模型的建模方法,而且与传统的热力学模型算法相比,新算法具有计算工作量小、计算结果较准确等特点,是一种便于在线应用的耗差分析模型。To improve the economical operation of the steam turbine, energy-loss models were built to provide operation adjustment guide by decomposing the total energy-loss of the turbine between current condition and optimal condition into losses of corresponding monitoring parameters. The equivalent enthalpy drop method was used to build energy-loss models of cycle parameters, which not only unifies the modeling method, but also is feasible for on-line application. Compared with traditional thermodynamics modeling, the proposed algorithm has the advantages of few-workload and accuracy.
