Results of an analysis of alternative power cycles for wellhead geothermal generating units are presented. The thermodynamic analysis of 240 power cycles was performed in order to identify optimum or near-optimum cycles for wellhead power plants over a wide range of geothermal resource temperatures. In addition to calculations of the efficiencies expected of practical cycles, the analysis included the characterization of various working fluids at each major state point in a power cycle. Characteristics of working fluids and power cycles expected to be near-optimum for resource temperatures of 200, 300, 400, 500, and 600 degree F (93, 149, 204, 260, and 316 degree C) are presented.
