| 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. |
