| Abstract: | A general matrix model for thermodynamic systems of power plants,applicable for computer software development,is being proposed,a program composed,and the model's correctness vindicated by calculating some practical examples.This model,which is based on the structural characteristics of thermodynamic systems and switching coefficients of regenerative heaters,highly abstracts the structural features of the heaters,and takes full account of the type of heater used,as well as its efficiency and the influence of auxiliary systems.The matrix model conforms with the configuration concept,the way of calculation proposed is reliable and generally applicable,suitable for analyzing and calculating the thermo-economic efficiency of large fossil fired power generating units,therewith providing a facile tool for developing real time monitoring and analyzing software.Figs 3,table 1 and refs 8. |
