摘　　要：分析在线性能计算软件在我国电厂的应用情况,把在线性能计算软件分为两类:编程式软件和组态式软件。编程式软件里的计算模型和变量值是完全被封装的,软件基本不具备扩展性。现有的组态式软件虽然具备一定的扩展性和可分析性,但是功能仍不够完善。提出在线性能计算软件变量二维计算顺序及索引模型,该模型包括三方面内容:第一,定义及构造了与计算变量和计算顺序相关的一系列集合和有序序列;第二,提出了变量二维排序算法;第三,建立了变量之间的引用和被引用关系,建立了变量二维索引图表。基于变量二维索引图表,可以方便地逐级追踪计算模型和计算变量的值,有利于增强组态软件的可分析性、扩展性和组态功能。The application of online performance calculation software to domestic power plants is analyzed.The online performance calculation software is classified as programmed software and model-building software.In programmed software,its calculation model and variable values are completely encapsulated,so that it lacks expansibility.Although present model-building software bears expansibility and analysability to a certain extent,its overall functionality is still incomplete.Therefore,the online performance calculation software variable two-dimensional calculation sequence and index model is proposed.The model consists of contents from three aspects：the first is the definition and establishment of a series of aggregation and sequences related to calculating variables and calculating sequences;the second is the introduction of variable two-dimensional sorting algorithm;the third is the establishment of references among variables as well as the variable two-dimensional index chart.Based on variable two-dimensional index chart,it is quite convenient to track stage by stage the values of the calculation model and calculation variables,so that it is helpful to enhance the analyzability,expansibility and model-building functionality of the model-building software.
