Abstract
The geothermal power generation is considered as one of the renewable energies. In these plants, power output depends on the conditions of well and ambient atmosphere. Aiming to operate geothermal power generation more effectively, it is desirable to investigate the influence of these conditional changes on power output quantitatively. Through the development of plant simulator for thermal efficiency based on the heat balance analysis, the power outputs were estimated for two types of noncondensable gas extractor system. The plant with vacuum pumps showed more power output than the one with ejectors, among the evaluated operational conditions.
