摘　　要：循环函数法是电厂热力系统节能分析的重要方法之一,而对电厂的各类辅助汽水循环分析往往也是火电厂节能分析的重点系统之一。基于循环函数法从能量平衡和质量平衡出发,构建了辅助汽水循环单元进水系数通用矩阵计算模型,并对矩阵填写规则进行了阐述。该模型通用性强、计算简单、易于计算机程序化。通过应用该模型的算例,验证了计算模型正确性与通用性。The cyclic functional method is one of the most important methods used for analysing energy-saving in the thermodynamic system of a power plant,and the analysis of various auxiliary steam-water cycles in power plant is also one of the most important points in energy-saving analysis of thermal power plants.Based on the cyclic functional method,a matrix calculation model for auxiliary steam-water cycles has been established through the energy and mass balance,and the rules for filling the matrix being also expounded.The said matrix model has the advantages of strong generality,simple computation,and easy programming in computers.The correctness and universality of said model have been proved by some examples calculated using this model.
