FIELD: power industry.SUBSTANCE: extra-terrestrial power plant with computer-aided energy conversion includes a closed circuit with a gaseous working medium implementing a closed thermodynamic Brayton cycle. The closed thermodynamic cycle includes a heat source, a turbocompressor kinematically connected to an electric generator, a heat regenerator, a heat exchanger that is connected through a heat transfer path to the gaseous working medium circuit, and through a heat receiving path to the closed circuit with liquid working medium for removal of low potential heat, which also includes a device for pumping of liquid working medium through the circuit, and a refrigerator emitting heat to outer space. The pumping device is made in the form of a turbo-pump unit kinematically connected to the electric generator. The heat exchanger is made in the form of a superheated steam generator using low potential heat taken from gaseous working medium of the power plant. The heat-emitting refrigerator is made in the form of a steam condenser with a function of further condensate cooling. The turbo-pump unit pump inlet is connected to the outlet of the flow path of the heat emitting refrigerator, the pump outlet is connected to the inlet of the heat receiving path of the heat exchanger - steam generator - in a counter-flow to its heat transfer path. The turbo-pump unit turbine inlet is interconnected with the outlet of the heat receiving path of the heat exchanger - steam generator, and its outlet is connected to the inlet of a hydraulic circuit of the heat emitting refrigerator.EFFECT: improving energy-mass characteristics of extra-terrestrial power plants with computer-aided energy conversion by reducing the fraction of the heat, which is discharged to atmosphere.1 dwg |
