Properties Database of Working Medium for Full Scope Simulation of Coal-Fired Power Plant

Abstract:

A properties database of working medium is developed based on the IAWPS-IF97 mathematical model to satisfy the demand of the accurate properties of full scope simulation of coal-fired power plant. The database provides the continuous relationship of the specific enthalpy, the density and the specific heat capacity as the function of the pressure and temperature. On this basis, a graphical user interface is designed to ensure the database can be used as a separate software kit. The error caused by regression algorithm can be avoided in the properties database. The properties database is suit for full scope simulation of coal-fired power plants and can also be used in the nuclear power plant. The results show that a single-step execution of matrix calculation of the properties database costs no more than 1ms CPU time in the Pentium IV 1.6GHz computer, fast enough for most real-time applications. Compared with the Chinese Standard, the mean relative error of the properties is less than 0.1% in full operation scope.
