Improvement to Power Plant Thermodynamic System Structure Matrix

The thermodynamic system structure matrix plays an important role in the analysis for the performance of thermodynamic system in power plant. In this paper, the thermodynamic system traditional structure matrix of power plant is improved, the structure matrix which considers thermal efficiency of the heater is inferred, this structure matrix has been integrated, and the rules to fill this matrix are also detailedly represented. The structure matrix is applied to the thermodynamic system analysis of the 300MW domestic unit. Through contrasting the calculation results, this improved structure matrix is proved to have stronger versatility and generality, its computing precision is higher, and it has very strong practicability in the production.
