【摘要】 开发一种通用的软件平台,利用系统创建的控件来组建一套热经济性在线分析软件,这样的开发方式对完成复杂热经济性在线分析软件具有重要的意义。本文阐述了在对火电机组热经济性在线分析系统的图形平台研究的基础上,建立了图形系统结构框架和图元模型,并进行了图形平台系统的开发以及支持图形平台的数据库系统开发,实现了热力系统的图元拖拽式绘制和机组特性数据的可视化输入。然后建立了矩阵的计算模型,在系统中实现了矩阵的加法、乘、求逆运算功能;并在系统中利用汽水系统通用数学模型的方法和矩阵运算程序对机组热经济性进行了计算,此计算非常简便,为其他经济性计算提供模版。更多还原

【Abstract】 The development mode which with components of the common software established to compose of thermal economic online analysis system software will have great significance in development thermal economic online analysis software.This paper has established the graphics system’s framework and graphics element model based on studied the graphics platform of the online analysis system software of thermal economic performance for coal-fired unit. And Paper describes the development of graphics platform and database administrator system, achieved the thermodynamic system drawing by graphics element drag-drawing and attributive dada visual input. Then established the matrix modal,make the matrix operation such as addition、multiply、inversion come true. In the system, computes the thermal economic performance of unit by use of the matrix operation and mathematical modal of the general steam-water. This method is very simple, can offer templates for other economic calculation.更多还原
