Optimization of cyclic parameters of a supercritical cycle for geothermal power generation

A supercritical power cycle with a regenerative process is studied to reach the maximum thermal efficiency by the choice of an appropriate working fluid and optimization of the cyclic state parameters, especially the condensing temperature or pressure. For given geothermal resources, the thermodynamic state parameters are calculated to show the features of the supercritical power cycle compared to other design results. The criteria for the choice of working fluids are also set up.
