ANALISIS PENGARUH TEMPERATUR LINGKUNGAN TERHADAP KONSUMSI BAHAN BAKAR SPESIFIK DAN EFISIENSI TURBIN GAS DI PLTGU INDRALAYA

Increasing electricity demand requires efficient and environmentally friendly power generation systems. Combined Cycle Power Plant (CCPP) have high efficiency levels because they combine the Brayton cycle in gas turbines and the Rankine cycle in steam turbines. The performance of Combined Cycle Power Plant is greatly influenced by gas turbine operating conditions, particularly ambient temperature, which determines the characteristics of the air entering the compressor. This study aims to analyze the effect of ambient temperature variations on specific fuel consumption (SFC), gas turbine efficiency, and changes in gas turbine performance. The research method was conducted through analysis of gas turbine operational data at ambient temperatures of 25 ℃ to 33 ℃ obtained during seven days of operation. The data obtained was then averaged and used to calculate the SFC and gas turbine efficiency values at each temperature variation. The results show that an increase in ambient temperature from 25 ℃ to 33 ℃ causes a decrease in SFC from 0.2745 kg/kWh to 0.2619 kg/kWh. This decrease in SFC is inversely proportional to gas turbine efficiency, which increases from 30.3689% to 31.8397%. In addition, an increase in turbine load causes the SFC to decrease and efficiency to increase. Changes in ambient temperature have also been shown to affect gas turbine output power due to changes in air density and combustion air mass. Thus, controlling and optimizing ambient temperature conditions plays an important role in improving the efficiency and performance of gas turbines in Combined Cycle Power Plant.
