Abstract

Indonesia has a geothermal energy resource potential of 40% of the world's potential and only 8.9% of Indonesia's geothermal potential has just been utilized. The spread of various geothermal locations in Indonesia will affect the characteristics of Geothermal Power Plants with different process types, so an analysis is needed to compare geothermal process technology and the conditions of the power generation system between flash steam and binary cycle to find out the technology. geothermal process and suitable system conditions at the Lahendong area expansion location. In this research, simulation of double flash steam and binary cycle with regeneration were carried out and the results were then analyzed based on the highest power output and efficiency. It was found that the double flash steam system produces a power of 3125 kW with a thermal efficiency of 89.8%. Meanwhile, the binary cycle system with generation produces a power of 5433.25 kW with a thermal efficiency of 8.68%. Based on the simulation results that have been carried out, the suitability of the process for the expansion of the Lahendong Area Geothermal Power Plant location uses binary cycle technology with a binary cycle with generation system.

LAHENDONG GENIŞLEME ALANI IÇIN JEOTERMAL ENERJI SANTRALI SÜREÇ TASARIMININ ANALIZI

Abstract

Endonezya, dünya potansiyelinin% 40'ı kadar bir jeotermal enerji kaynağı potansiyeline sahiptir ve Endonezya'nın jeotermal potansiyelinin sadece% 8.9'u yeni kullanılmıştır. Endonezya'daki çeşitli jeotermal konumların yayılması, farklı proses türlerine sahip Jeotermal Enerji Santrallerinin özelliklerini etkileyecektir, bu nedenle jeotermal proses teknolojisini ve teknolojiyi bulmak için flaş buhar ve ikili döngü arasındaki enerji üretim sisteminin koşullarını karşılaştırmak için bir analize ihtiyaç vardır. Lahendong bölgesi genişleme konumunda jeotermal süreç ve uygun sistem koşulları. Bu araştırmada, çift flaş buhar ve rejenerasyon ile ikili çevrim simülasyonu gerçekleştirilmiş ve sonuçlar daha sonra en yüksek güç çıkışı ve verimliliğine dayalı olarak analiz edilmiştir. Çift flaşlı buhar sisteminin% 89.8'lik bir termal verimlilikle 3125 kW'lık bir güç ürettiği bulunmuştur. Bu arada, üretimli ikili çevrim sistemi,% 8.68'lik bir termal verimlilikle 5433.25 kW'lık bir güç üretir.
