Optimisation of Cooling System Design Parameters for a Geothermal Power Plant

Abstract

The selection of cooling design for a geothermal power plant directly affects the annual energy generation, steam and capital cost. consist of condenser pressure, wet bulb temperature and cooling tower approach t rature, are used to size the cooling system. The final aelection of the design dependent upon an study which tially an economic between capital and operating expenditures revenues f r a the energy generated. The objective of the study is the aelection of design which the overall unit cost of the energy generated for the life of the plant. This the and procedures for the selection of design for a geothermal power plant using cooling system. The selected design parameters, which The relevant presented have been used to facilitate selection of design parameters for a geothermal plant in Indonesia. results this optinisation are given, together with a sensitivity analysis, to the procedures for the selection of the optimum design parameters.
