PEMANFAATAN CYCLE TEMPO DALAM ANALISIS EKSERGI PADA PEMBANGKIT LISTRIK TENAGA UAP DENGAN VARIASI BEBAN DI PLTGU INDRALAYA

The increasing demand for electrical energy along with industrial and population growth demands increased efficiency of the generating system. Exergy analysis is a comprehensive approach to assess the efficiency of the generating system because it considers both the quantity and quality of energy. This study aims to analyze the thermodynamic performance of the Steam Power Plant (PLTU) at the Indralaya Combined Cycle Power Plant (CCPP) using Cycle-Tempo software with variations in operating loads of 12.57 MW, 11.18 MW, and 10.56 MW. The research method includes collecting actual operating data, modeling the system in Cycle-Tempo, and comparing simulation results with manual calculations to determine the exergy efficiency and irreversibility of each component. The analysis results show that the HP Drum has the highest Functional Efficiency Exergy value of 99.92%, while the lowest value is found in the Condensate Extraction Pump (CEP) at 18.12%. The highest Universal Efficiency Exergy value is also obtained in the HP Drum at 99.95%, and the lowest in the Cooling Tower at 6.80%. The component with the highest level of irreversibility is the HP Evaporator, while the LP Drum shows the lowest irreversibility. Comparison between manual and simulation results shows an excellent level of agreement with an average deviation of less than 2%. These results indicate that Cycle-Tempo is able to represent actual operating conditions with high accuracy. This study recommends focusing efficiency improvements on the Condenser and HP Evaporator as the components with the greatest exergy loss.
