Abstract
Geothermal power plants are often operated off design point because of the change of ambient conditions, like air temperature, production well and deterioration of the components. For this reason, thermodynamic performance analysis simulator for geothermal power plant was developed. Quantitative evaluation on the influence for overall plant could be performed at the time that outside conditions and performance of plant components varied. By this simulator, power output and variation of exhaust vacuum accompanying with ambient temperature, production well condition and related parameters can be analyzed. This simulator is useful how planning of the plant maintenance strategy and its operation.
