摘　　要：针对生产实际中,现有火电厂汽轮机系统的测点经常不够完备,或者有些测点由于长期未校准等原因而使测量不准确,甚至个别测点为坏点,使得热力系统热经济性的在线分析遇到困难[1],提出了合成抽汽焓的概念,并据此研究了疏水参数缺损环境下热力系统热经济性分析的能效分布矩阵方程,同时利用人工神经网络计算模型解决了合成抽汽焓的计算问题。In actual production, conventional points of steam turbine is not enough, and some test points are not correct because they are not calibrated for long period, even individual points can not be used. It can not analyze and calculate the thermal economic behavior on-line with this points. The concept of composed enthalpy is put forward and the thermal economic behavior analysis in the condition of parameter defecting using energy-efficiency distribution matrix is studied, and the composed enthalpy using the neural network model is caculated. It offers a available approach for the thermal economic behavior analysis in the condition of parameter defecting.
