Optimization of the thermal power plant operation by distributing exergy flows in the heat pump

Abstract

The possibility of wide use in practice and implementation of optimization of a thermal and power plant on the basis of exergy analysis with the use of target functions are presented in the article. A tree of thermal economic costs of a solar thermal supply system with possible distribution of flows in a thermal and power plant with the representation of a block diagram is considered. The exergy characteristics of each element of the system are given in the form of dependence. It determines the exergy flux density of total solar radiation on the surface of solar collectors. The schedule of total solar radiation, average monthly air temperature and total exergy amount of the city of Krasnodar as well as the graphs of distribution of the price of 1kW of exergy for months of a year were taken into account. The distribution of exergy flows in the heat pump and its energy efficiency are estimated by the coefficient of conversion.
